FUNDAMENTALS [001] Conventional footwear items generally include two primary elements, an upper and a sole structure. The upper part is attached to the sole structure and forms a void inside the shoe to receive the foot comfortably and safely. The sole structure is attached to a lower area of the upper, thus being positioned between the upper and the ground. In athletic shoes, for example, the sole structure may include a medium sole and an outer sole. The midsole often includes a polymer foam material that attenuates ground reaction forces to reduce stresses on the foot and leg during walking, running and other walking activities. In addition, the midsole may include chambers filled with fluid, plates, moderators or other elements that further attenuate forces, increase stability or influence foot movements. The outer sole is attached to a lower surface of the midsole and provides a ground engaging portion of the sole structure formed of a durable and wear-resistant material, such as rubber. The sole structure can also include a sock lining positioned within the void and proximal to a lower surface of the foot to increase shoe comfort. [002] The upper part generally extends over the instep and toe areas, along the medial and lateral sides of the foot, under the foot and around the heel area of the foot. In some footwear items, such as basketball shoes and boots, the upper may extend upward and around the ankle to provide support or protection for the ankle. Access to the void inside the upper is usually provided by an ankle opening in a region of the heel of the shoe. A shoelace system is often incorporated at the top to adjust the fit of the upper, thereby allowing the foot to enter and remove the void within the upper. The shoelace system also allows the user to modify certain dimensions of the upper part, particularly the circumference, to accommodate feet with varying dimensions. In addition, the upper part may include a tongue that extends under the shoelace system to increase the shoe's adjustability and the upper part may incorporate a counter-heel to limit the movement of the heel. [003] A variety of material elements (eg, textiles, polymer foam, polymer sheets, leather, synthetic leather) are conventionally used in the manufacture of the upper. In athletic shoes, for example, the upper may have multiple layers, each of which includes a variety of elements of joined material. As examples, material elements can be selected to provide stretch resistance, wear resistance, flexibility, air permeability, compressibility, comfort and moisture flow to areas other than the top. In order to grant different properties for different areas of the upper part, the elements of the material are often cut to desired shapes and then joined, usually with stitching or adhesive bonding. In addition, material elements are often joined in a layered configuration to grant multiple properties for the same areas. As the number and type of material elements incorporated at the top increase, the time and cost associated with transporting, storing, cutting and joining the material elements may also increase. Leftover material from the cutting and sewing processes also accumulates to a greater degree, as the number and type of material elements incorporated in the upper part increase. Furthermore, upper parts with a greater number of material elements may be more difficult to recycle than upper parts formed of fewer types and numbers of material elements. By decreasing the number of material elements used at the top, therefore, the leftover can be reduced while increasing the efficiency of manufacturing and the recycling capacity of the top. SUMMARY [004] An article of footwear is revealed below as having an upper and a sole structure attached to the upper. A knitted component of the upper part is formed of unitary knitted fabric construction and includes a half portion and a tongue portion. The sock portion has a hollow structure (a) forming an ankle opening in a region of the heel of the shoe and (b) extending between the heel region and a forefoot region of the shoe to define a void within the shoe for receive a foot. The tongue portion has an elongated configuration (a) extending across at least a portion of the length of the upper entry area and (b) including two layers of knitted fabric which are adjacent. [005] A shoe item can also have a knitted component and a cover component. The knitted component (a) forms an ankle opening in a heel region of the shoe and (b) extends between the heel region and a forefoot region of the shoe to define a void within the shoe to receive a foot . Most of the knitted component is formed of a first layer of knitted fabric, but a portion of the knitted component located in an entrance area of the upper part has a layered structure that includes the first layer of knitted fabric. , a second layer of knitted fabric and a third layer of knitted fabric. Each of the first layer of knitted fabric, the second layer of knitted fabric and the third layer of knitted fabric is formed from the unitary knitted fabric construction. The cover component is attached to the sole structure and extends between the entry area and the sole structure, with the mesh component being at least partially located within the cover component. [006] A method for making a shoe article may include using a circular knitting process to form a knitted component making a knitted sock and two substantially coextensive layers located within the sock and extended over at least a portion the length of the sock. In addition, the knitted component is incorporated into the upper part of the shoe. [007] The advantages and characteristics of the aspects that characterize the novelty of the invention are particularly evident in the attached claims.

DETAILED DESCRIPTION [024] The following discussion and accompanying figures reveal a variety of concepts related to knitted components and the manufacture of knitted components. Although knitted components are revealed with reference to footwear items having configurations that are suitable for running and basketball, the concepts associated with knitted components can be applied to a wide range of athletic shoe styles, including tennis shoes. baseball, football shoes, golf shoes, hiking shoes and boots, ski and snow ski boots, soccer shoes, tennis shoes, training shoes and hiking shoes, for example. The concepts associated with knitted components can also be used with shoe styles that are generally considered to be non-athletic, including dress shoes, loafers, sandals and work boots. Thus, a variety of shoe styles and configurations can incorporate the concepts discussed here. GENERAL FOOTWEAR CONFIGURATION [025] A shoe item 100 is shown in Figures 1 to 5 as including a sole structure 110 and an upper 120. While the sole structure 110 is located under and supports a user's foot, the upper 120 provides a comfortable and safe foot cover. As such, the foot can be located inside the upper part 120 to effectively hold the foot inside the shoe 100 or otherwise join the foot and shoe 100. In addition, the sole structure 110 is attached to a lower area of the foot. upper part 120 and extends between the foot and the ground to attenuate the reaction forces of the ground (ie, cushion the foot), provide traction, increase stability and influence the movements of the foot, for example. [026] For reference purposes, shoe 100 can be divided into three general regions: a front region of the foot 101, a middle region of the foot 102 and a region of the heel 103. The front region of the foot 101 generally includes portions of the shoe 100 corresponding with the toes and joints connecting the metatarsals with the phalanges. The middle region of the foot 102 generally includes portions of the shoe 100 corresponding to the area of the arch of the foot. The heel 103 region generally corresponds to the back portions of the foot, including the calcaneus bone. Footwear 100 also includes a side face 104 and a medial face 105, which extend through each of regions 101 to 103 and correspond with opposite sides of footwear 100. More particularly, side face 104 corresponds to the outer area of the foot (i.e., the surface facing away from the other foot) and the medial face 105 corresponds with the inner area of the foot (i.e., the surface facing the other foot). Regions 101 to 103 and faces 104 and 105 are not designed to demarcate precise areas of footwear 100. Instead, regions 101 to 103 and faces 104 and 105 are designed to represent general areas of footwear 100 to aid in the discussion Following. In addition to footwear 100, regions 101 to 103 and faces 104 and 105 can also be applied to sole structure 110, upper 120 and their individual elements. [027] The primary elements of the sole structure 110 are a medium sole 111 and an outer sole 112. The medium sole 111 is attached to the bottom surface of the upper 120 and may be formed of a compressible polymer foam element (for example , a polyurethane or ethyl vinyl acetate foam) that attenuates the reaction forces of the ground (that is, it produces cushioning) when compressed between the foot and the ground during walking, running or other walking activities. In additional configurations, the midsole 111 may incorporate plates, moderators, chambers filled with fluid, durable elements or movement control members that further attenuate forces, increase stability or influence foot movements, or the midsole 21 may be formed primarily from a fluid-filled chamber. The outsole 112 is attached to the bottom surface of the midsole 111 and can be formed of a wear-resistant rubber material that is textured to provide traction. In addition, the sole structure 110 may include a sock liner located inside the upper 120 and is positioned to extend under the bottom surface of the foot to increase the comfort of the shoe 100. Although this configuration for the sole structure 110 provides an example of a sole structure that can be used in conjunction with the upper part 120, a variety of other conventional or unconventional configurations for sole structure 110 can also be used. Thus, the characteristics of the sole structure 110 or any sole structure used with the upper part 120 can vary considerably. [028] The upper 120 defines a void 121 within the shoe 100 to receive and secure the foot in relation to the sole structure 110. The void 121 is formed to accommodate the foot. When the foot is located within the void 121, therefore, the upper part 120 extends along a lateral side of the foot, along the medial face of the foot, over the foot, around the heel and under the foot. A collar 122 is located in at least the region of the heel 103 and forms an ankle opening 123 that allows access to the foot to the void 121. When the foot is located within the void 121, the collar 122 and the ankle opening 123 extend around or otherwise wrap around the ankle. The upper part 120 also has a shoelace system located in an entrance area 124 of the upper part 120, which is located primarily in the middle region of the foot 102 and corresponds with a region of the instep or upper surface of the foot. The shoelace system includes a shoelace 125 that extends (a) through several openings 126 in the upper part 120 and (b) repeatedly through the entry area 124. The shoelace system helps to tighten the upper part 120 around the foot and loosening portions of the upper part 120 to allow entry and removal of the foot from the void 121. As an alternative to openings 126, the shoelace system may include other shoelace receiving elements, such as D rings, hooks or various wires elastic with link. Additional configurations of the upper 120 may also include one or more of (a) a heel in the heel region 103 to increase stability, (b) a toe guard in the forefoot 101 which is formed of a wear-resistant material and (c) logos, trademarks and notices with care instructions and material information. In this way, the upper part 120 can incorporate several characteristics and elements, in addition to the characteristics and elements discussed here and shown in the figures. [029] Most of the upper part 120 is formed of a component made of mesh 130 and a component of cover 140. The component made of mesh 130 has a structure made of mesh and is formed from the construction of unitary mesh fabric (ie is, as an element of a piece) through a knitting process. When incorporated in the upper part 120, the knitted component 130 extends through each of the regions 101 to 103 and between the faces 104 and 105. Although primarily located within the upper part 120, portions of the knitted component 130 are exposed in the region of the heel 103 and entry area 124. In addition to forming the collar 122 and the ankle opening 123, the knitted component 130 defines most or all of the void 121. As such, the foot located within the void 121 (or a sock covering the foot) will touch and remain against the knitted component 130. The covering component 140 is attached to the sole structure 110 and is located outside the knitted component 130, thereby covering various areas of the component made of mesh 130. When incorporated in the shoe 100, the covering component 140 extends through each of the regions 101 to 103, between the faces 104 and 105 between the component made in mesh 130 and the sole structure 110. This that is, a portion of the covering component 140 may extend between the entrance area 124 and an area where the upper part 120 is attached to the sole structure 110. Although the structure of the covering component 140 can vary significantly, the covering component 140 can be formed of multiple material elements (for example, textiles, polymer foam, polymer sheets, leather, leatherette) that are joined together by sewing or joining, for example. Furthermore, the cover member 140 may have a layered structure that includes multiple elements of overlapping material. [030] The component made of mesh 130 is separable and can be removed from the rest of the shoe 100, as shown in figure 5. That is, the component made of mesh 130 is not attached to other parts of the upper 120 and can be removed repeatedly and inserted into the cover component 140. In order to place the shoe 100 on the foot, the user can first place the knitted component 130 on the foot and then locate the knitted foot and component 130 inside the component of the cover 140. Alternatively, the user can first place the knitted component 130 inside the cover component 140 and then locate the foot inside the knitted component 130. Although components 130 and 140 are separable, the component made mesh 130 can be attached (for example, by sewing, adhesive bonding, thermal bonding) to the covering component 140 or other upper portion portions 120 in some shoe configurations 100. [031] The upper 120 includes an outer surface 127 and an opposite inner surface 128. The outer surface 127 is a portion of the outer surface of the shoe 100 and is formed primarily by both the knitted component 130 and the covering component 140 The knitted component 130 is exposed in the region of the heel 103 and entrance area 124, thereby forming portions of the outer surface 127 in these areas. Similarly, the covering component 140 forms portions of the outer surface 127 between the entrance area 124 and the sole structure 110. While the outer surface 127 is formed cooperatively by each of the knitted component 130 and the covering component 140 , the knitted component 130 forms most or all of the inner surface 128, which also defines a portion of the void 121. As such, the foot located within the knitted component 130 will touch portions of the inner surface 128. [032] The advantages of the 130 mesh component include stretch and recovery properties, as well as better fit and comfort. When locating the foot within the void 121, the collar 122 can stretch to allow the foot to enter the void 121 through the ankle opening 123. As the foot progresses into the upper 120, portions of the knitted component 130 located in the entry area 124 can also stretch to allow the foot to fully enter the void 121. In addition to stretching, the knitted component 130 can retrieve or contract to secure the foot within the upper 120. More particularly, the collar 122 it can recover to extend securely around the ankle and other portions of the knitted component 130 can recover to pull the cover component 140 against the foot, thereby tightening the upper part 120 around the foot. Several features of the knitted 130 component, including mesh fabric materials and structure, can be used to provide specific stretch and recovery properties for the knitted 130 component. That is, the degree of stretch and recovery can be designed to inside the 130 mesh component. As a result, the 130 mesh component can be designed to extend around the ankle and tighten the upper 120 around the foot in a way that increases the overall fit of the shoe 100. In addition In addition, the 130 mesh component can be designed with additional layers or padded portions in the entry area 124 to separate and cushion the foot because of the lace 125. Furthermore, the 130 mesh component is located against the foot and increases the overall comfort of shoes 100. KNITTED COMPONENT CONFIGURATION [033] The knitted component 130 is represented individually and separated from the rest of the shoe 100 in figures 6 to 11 D. Although the knitting process for making the knitted component 130 is discussed in great detail below, the component made in mesh 130 is formed of at least one yarn that is manipulated (for example, with a knitting machine) to form a plurality of entangled loops that define a variety of sequences and textures. That is, the knitted component 130 has the structure of a knitted textile. Furthermore, the knitted component 130 is formed from the construction of unitary knitted fabric. As used herein, a knitted component (for example, the knitted component 130) is defined as being formed from the "unitary knitted fabric construction" when formed as a single piece element through a knitting process. That is, the knitting process substantially forms the various characteristics and structures of the knitted component 130 without the need for significant additional fabrication steps or processes. Although portions of the knitted component 130 may be joined (for example, edges of the knitted component 130 being joined) following the knitting process, the knitted component 130 remains formed from the construction of unitary knitted fabric because it is formed as a one-piece knitted fabric element. Additionally, the knitted component 130 remains formed from the construction of unitary knitted fabric when other elements (for example, stabilizers, stretch limiting elements, straps, aesthetic characteristics, logos, trademarks and notices) are added following the process of knitting. [034] Although the configuration of the knitted component 130 can vary considerably, the knitted component 130 is represented as including a sock portion 131 and a tongue portion 132. The sock portion 131 has the general configuration of a sock and therefore forms a generally cylindrical and hollow structure for receiving the foot. The tongue portion 132 is located within the sock portion 131 and has an elongated structure that extends over most of the length of the sock portion 131. When incorporated into the shoe 100, the sock portion 131 forms the collar 122, defines the ankle opening 123 and extends the entire length and width of the shoe 100. The tongue portion 132 is located inside and extends through the entrance area 124 or at least a portion of the entrance area 124. In addition to moreover, the tongue portion 132 is positioned to extend between the foot and the shoelace 125 to separate and cushion the foot because of the shoelace 125. [035] The sock portion 131 usually includes a collar area 151, a foot area 152 and a toe area 153. The collar area 151 forms an opening that provides access to the interior of the 130 mesh component. as such, the area of collar 151 forms the collar 122 and defines the opening of the ankle 123 in the shoe 100. Although the area of the collar 151 is represented as having a two-layer configuration, portions of the area of the collar 151 can also be formed in a layer of single mesh fabric. The foot area 152 forms most of the sock portion 131 and provides the generally cylindrical and hollow structure of the sock portion 131, in which the foot is located. The finger area 153 is located opposite the collar area 141 and forms a closed end of the sock portion 131 that receives the user's fingers. Based on this discussion, and as mentioned above, the sock portion 131 has the general configuration of a sock and can have the general configuration of a variety of conventional socks. That is, the sock portion 131 may incorporate various features and structures of knitted fabric that are generally used in socks that are designed to cover a foot. Given the single use for the knitted component 130, the sock portion 131 can also incorporate several unconventional structures that differ from those found in conventional socks. [036] The tongue portion 132 extends longitudinally through the foot area 152 and is secured on opposite sides of the foot area 152. More particularly, the collar end 154 of the tongue portion 132 is secured to the adjacent sock portion 131 to the collar area 151 and an opposite finger end 155 of the tongue portion 132 is attached to the sock portion 131 adjacent to the finger area 153. Although the area between ends 154 and 155 can be attached to the sock portion 131, that area is represented as not being trapped. As discussed in more detail below, tongue portion 132 can be formed from unitary knit fabric construction with sock portion 131. As such, one or both ends 154 and 155 can be formed from unitary knit fabric construction. with the sock portion 131. In the exemplary configuration shown in the figures, however, the end of the fingers 155 is joined to the sock portion 131 with seam 133, while the end of the collar 154 is formed of unitary knitted fabric construction with the half portion 131. [037] Although the tongue portion 132 may be formed of a single layer of textile material, the tongue portion 132 is represented as including a first layer of mesh fabric 156 and a second layer of mesh fabric 157 that are substantially coextensive and they stand against each other. The first layer of knitted fabric 156 also lies against the stocking portion 131. The layers of knitted fabric 156 and 157 are formed during the knitting process and joined together through the knitting process, thereby being formed from fabric construction unitary mesh. Although the specific locations in which the knitted fabric layers 156 and 157 are joined may vary, the edges or peripheral areas of the knitted fabric layers 156 and 157 are represented as being joined, while the central areas of the fabric layers mesh 156 and 157 are represented as not being joined. In reality, therefore, the layers of the knitted fabric 156 and 157 are separate layers of the knitted material, but are joined at their peripheries. An advantage in joining the layers of the knitted fabric 156 and 157 is to maintain the relative positions of the layers of the knitted fabric 156 and 157 following the knitting process and while the knitted component 130 or footwear 100 is being used. In other configurations of the knitted component 130, however, the peripheral areas of the fabric layers 156 and 157 may not be joined or both the peripheral and central areas may be joined. [038] The knitted component 130 is formed of unitary knitted fabric construction, however the knitted component 130 may include the seam 133 that joins the fingertips 155 in the sock portion 131. During the knitting process for the knitted component 130, which is discussed in more detail below, each of the sock portion 131 and tongue portion 132 is formed and joined. More particularly, the knitting process joins the collar end 154 into the sock portion 131. After the knitting process is complete, the fingertips 155 are joined to the seam portion 131 with seam 133. In additional configurations, the process can knit the end of fingers 155 into the sock portion 131 and the seam 133 can be located at the end of the collar 154. It may also be possible to join both ends 154 and 155 during the knitting process, thereby eliminating the need for seam 133. [039] An advantage of forming the tongue portion 132 including both layers of mesh fabric 156 and 157 is to provide additional separation and cushioning between the foot and the shoelace 125. When incorporated into the shoe 100, both layers of the mesh fabric 156 and 157 are positioned between the foot and the shoelace 125. Furthermore, a portion of the sock portion 131 also extends between the foot and the shoelace 125. In reality, therefore, three layers of fabric material from mesh separates the foot of the shoelace 125 in the entry area 124, while other portions of the knitted component (for example, sock portion 131) may have a single layer that separates the foot from other portions of the upper 120. Each of the layers of the knit fabric provides a degree of cushioning that protects the foot against the laces 125. In combination, however, the three layers of the knit fabric provide greater separation and cushioning, thereby increasing the overall comfort of the shoe 100. In some con figures, tongue portion 132 may include only one layer of knitted fabric or may include three or more layers of knitted fabric. In other configurations, a foam material or other element can be used to provide even more separation and cushioning between the foot and the shoelace 125. [040] The knitted component 130 can be formed from a single type of yarn that provides properties for each of the stocking portion 131 and tongue portion 132. In order to vary the properties of the knitted component 130, however, different yarns can be used in different areas of the knitted component 130. That is, portions 131 and 132 or different areas of portions 131 and 132 can be formed of different yarns to vary the properties between the areas of the knitted component 130 In addition, an area of the knitted component 130 may be formed from a first type of yarn or combinations of yarns that grant a first set of properties and another area of the knitted component 130 may be formed from a second type of yarn thread or combination of threads that grants a second set of properties. The properties can vary throughout the 130 mesh component, therefore, by selecting specific yarns for different areas of the 130 mesh component. Examples of properties that can be varied by choosing the yarn include color, shape, shine, stretch , recovery, "loft", touch ("hand"), moisture absorption, biodegradable capacity, abrasion resistance, durability and thermal conductivity. It should also be noted that two or more threads can be used in combination to take advantage of the properties of both threads, such as when the threads are coated or form different sequences in the same area. [041] The properties that a particular type of yarn will impart to a 130 mesh component area depend partially on the materials that form the various filaments and fibers within the yarn. Cotton, for example, provides a soft touch, natural aesthetics and biodegradable capacity. Elastomer and elastic polyester individually provide substantial stretch and recovery, with elastic polyester also providing recycling capacity. Rayon has high brightness and moisture absorption. Wool also has high moisture absorption, in addition to insulating properties and biodegradable capacity. Nylon is durable, resistant to abrasion and has relatively high strength. Polyester is a hydrophobic material that also has relatively high durability. Yarns incorporating thermoplastic materials can also allow areas of the 130 mesh component to be fused or stabilized through the application of heat. In addition to the materials, other aspects of the yarns selected for the 130 mesh component can affect the properties. For example, a yarn forming the knitted component 130 may be a monofilament yarn or a multiple filament yarn. The yarn can also include separate filaments that are each formed from different materials. In addition, the yarn may include filaments that are individually formed from two or more different materials, such as a bicomponent yarn with filaments having a core-clad configuration or two halves formed from different materials. Different degrees of twist and ruffle, as well as different deniers, can also affect the properties of the 130 mesh component. In this way, both the materials that form the yarn and other aspects of the yarn can be selected to provide a variety of properties for areas separate from the 130 mesh component. [042] In addition to the type of yarn that is selected for the knitted component 130, the structure of the knitted fabric in the knitted component 130 grants particular properties. As shown, most of the knitted component 130 is formed to have a common or single knitted fabric structure, which is relatively untextured and can be referred to as a tubular or single knitted fabric. In additional configurations, however, the knitted component 130 may have a wavy mesh fabric structure or tangled mesh fabric or the knitted component 130 may have a hybrid mesh fabric structure, in which multiple types of Knitted fabric structures are used in one area. In order to vary the properties of the knitted component 130, different woven structures can be used in different areas of the knitted component 130. That is, portions 131 and 132 or different areas of 131 and 132 can be formed of different knitted fabric structures to vary the properties between the areas of the knitted component 130. Furthermore, an area of the knitted component 130 can be formed from a first knitted fabric structure or combination of fabric structures Knitted fabric that provides a first set of properties and another area of the knitted component 130 can be formed from a second fabric structure or combination of knitted fabric structures that provides a second set of properties. Properties can vary across the 130 mesh component, therefore, by selecting specific mesh fabric structures for different areas of the 130 mesh component. Examples of properties that can be varied by choosing the yarn include shape, shine , stretching, recovery, loft, touch, moisture absorption, abrasion resistance, durability and thermal conductivity. [043] The properties can be further varied by selecting both the type of yarn and the structure of the knitted fabric that is used in the 130 knitted component or in the 130 knitted component areas. By combining several types of yarn with several knitted fabric structures, additional combinations of properties can be granted for the knitted component 130. For example, a first type of yarn and a first knitted fabric structure can be used in an area of the knitted component 130 to provide a set of properties and a second type of yarn and a second mesh fabric structure can be used in a different area than the knitted component 130 to provide a different set of properties. As an example, the sock portion 131 may incorporate yarn types and knit structures that provide high stretch, and the tongue portion 132 may incorporate loft types and knit structures that provide loft and little stretch. Given the two-layer configuration in the collar 151 area, the outer layer can incorporate yarn types and knitted fabric structures that provide durability and wear resistance, and the inner layer can incorporate yarn types and knitted fabric structures that they conceive stretching and recovery. In addition, some portions of the foot area 152 may have a wavy mesh fabric structure with a higher denier thread and other portions of the foot area 152 may have a simple mesh fabric structure with a lower denier thread. Portions of the sock portion 131 may also incorporate types of yarn and mesh structures that drip moisture away from the foot. In this way, the selection of particular combinations of yarn types and knitted fabric structures for each area of the knitted component 130 allows each area to have a particular combination of beneficial properties. [044] An advantage of footwear 100 refers to the ability to separate the knitted component 130 from the rest of footwear 100. Different individuals have different shapes and proportions of the foot, as well as different preferences regarding various aspects of the footwear. Therefore, each individual can select a component configuration made in mesh 130 that best suits their proportions and preferences. Furthermore, an individual may substitute a component made in mesh 130 with another component made in mesh 130 based on the planned activity during which footwear 100 is planned to be worn. The ability to replace the knitted component 130 also allows footwear 100 to have various aesthetics, depending on which the knitted component 130 is used. Thus, various aspects of footwear 100 may vary depending on the specific configuration of the knitted component 130 that is used with footwear 100. [045] Although separability provides several advantages, non-separable configurations also have several advantages. For example, the knitted component 130 provides an essentially seamless surface that rests against the foot, thereby increasing the comfort of the shoe 100. Furthermore, the use of the knitted component 130 increases the efficiency of manufacturing the shoe 100 and decreases the number of separate elements that need to be joined in the manufacture of the upper part 120. [046] Based on the above discussion, a portion of the upper part 120 incorporates the component made of mesh 130, which is formed from the construction of unitary mesh fabric. The knitted component 130 may include both the sock portion 131 and the tongue portion 132. The sock portion 131 has a generally cylindrical and hollow structure that forms the ankle opening 123 that extends between regions 101 and 103 to define the void 121. The tongue portion 132 has an elongated configuration (a) extending across at least a portion of the length of the entry area 124 and (b) including two layers of mesh fabric 156 and 157 which are adjacent to each other . One of the layers of the mesh fabric 156 and 157 can also be against the stocking portion 131 in the entry area 124. Given this structure, most of the knitted component 131 is formed from the stocking portion 131, which is often a layer of single mesh fabric. In the entry area 124, however, the upper part 120 has a layered structure that includes the mesh fabric layer of the sock portion 131 and each of the mesh fabric layers 156 and 157. In addition, each of the portions 131 and 132 and the three layers of the knitted fabric are formed of unitary knitted fabric construction. ADDITIONAL SETTINGS [047] The configuration of the shoes 100 and the knitted component 130 discussed above and represented in the figures presents an example related to the structure of the shoes 100 and the knitted component 130. In additional configurations, numerous characteristics of the shoes 100 and the 130 mesh component can vary considerably. Referring to Figure 12A, for example, a plurality of stranded yarns 161 forms receiving elements for the shoelace and replaces the openings 126. The stranded yarns 161 extend upwards from the lower upper area 120 and form links, through the which shoelace 125 extends. Additional information related to wire-like structures with links 161 can be found in US Patent Application 13 / 529,381, which was filed with the US Patent and Trademark Office on June 21, 2012 and is entitled Footwear Incorporating Looped Tensile Strand Elements, such order being incorporated here entirely by reference. Although the knitted component 130 can be separable and replaceable, figure 12B represents a configuration where the seam 162 joins the knitted component 130 in the cover component 140. Although the shoe 100 may have the configuration of a running shoe, another configuration of shoe 100 is shown in figure 12C as having the configuration of a basketball shoe. [048] In addition to variations in other areas of footwear 100, numerous features of the knitted component 130 can vary considerably. Referring to figure 13A, the knitted component 130 includes a wavy mesh fabric structure. More particularly, substantially the entire upper surface of the foot area 152 has the structure of wavy mesh fabric. In addition, a portion of the bottom surface of the foot area 152 that corresponds with the position of the arch of the foot has the structure of wavy mesh fabric. In comparison with other mesh fabric structures, the corrugated mesh fabric structure can be used to provide significant stretch to the knitted component 130. In another configuration that is shown in Figure 13B, lateral regions of the foot area 152 have a matted fabric structure that forms a plurality of holes or openings in the knitted component 130. An advantage of the matted fabric structure is breathability. Although the tongue portion 132 may be located within the sock portion 131, Figure 13C represents a configuration where the tongue portion 132 is located outside the sock portion 131. [049] In some variations, the proportions of the 130 mesh component may vary. As an example, figure 13D represents the area of collar 151 as having the highest height, which would cover most of the user's ankle. Referring to Figure 14A, the tongue portion 132 exhibits a reduced length that would extend across less than the entry area 124. Figure 15A represents a configuration where the tongue portion 132 is wider. Similarly, the width of the tongue portion 132 is also greater in figure 15B and extends to the lateral areas of the sock portion 131. As a further variation, figure 15C represents the second layer of mesh fabric 157 as having a greater thickness , which can be formed by varying the structure of the knitted fabric or the type of yarn. [050] Numerous other aspects of the 130 mesh component may also vary. With reference to figure 14B, the end of the fingers 155 is sewn to the sock portion 131, while the end of the collar 154 is formed of unitary mesh fabric construction with the sock portion 131. In figure 14C, both ends 154 and 155 are formed of unitary knit fabric construction with the sock portion 131. In order to provide greater padding and separation between the foot and the shoelace 125, the thickness of one of the layers of the knit fabric 156 and 157 can be increased, as in figure 15C. As additional examples, Figure 14D represents a foam element 162 located between the layers of the mesh 156 and 157 and Figure 15D represents the tongue portion 132 as having an additional layer of the mesh 163. Referring to Figure 14E , the tongue portion 132 is formed to have the configuration of a spacer material, in which fallen threads extend between the sock portion 131 and the tongue portion 132 to produce the padding. As a final example, Figure 14F represents a configuration in which the tongue portion 132 is located to extend under the foot and can provide cushioning similar to a sock liner. KNITTING PROCESS [051] A knitting process can be used to form the 130 mesh component and many or all of the various features discussed above for the 130 mesh component. It should be noted, however, that weaving processes can also be used to form a textile element having many or all of the various characteristics discussed above for the knitted component 130. While a knitting process that forms the knitted component 130 can be performed by hand, commercial manufacture of multiple knitted components 130 it will usually be performed by knitting machines. In general, knitting involves forming sequences and textures of tangled loops of one thread or multiple threads. In production, knitting machines can be programmed to mechanically manipulate one or more threads for the configuration of the 130 mesh component. That is, the 130 mesh component can be formed by mechanically manipulating one or more threads to form a textile element. single piece that has the shape and characteristics of the 130 mesh component. As such, the 130 mesh component can be formed from the construction of unitary mesh fabric using a knitting machine. [052] Although the 130 mesh component can be formed through a variety of different knitting processes and using a variety of different knitting machines, the formation of the circular mesh (ie the use of a circular knitting machine) has the ability to form the 130 mesh component to have the various features discussed above. In general, circular mesh formation involves forming a plurality of sequences and textures. As an example, strings are circular rows of loops that extend entirely around the middle portion 131 and across the width of the tongue portion 132. Textures are columns of loops that extend perpendicular to the strings and the (a) collar area 151 for the finger area 153 and (b) from the collar end 154 to the finger tip 155. Although general or conventional circular knitting processes can be used to form the knitted component 130, specific examples of knitting processes that can be used include wide tube circular knitting, narrow tube circular knitting, narrow tube circular knitting jacquard, single knitting circular knitting jacquard, double knitting circular knitting jacquard, jacquard of woven mesh and flat knitwear, for example. [053] The knitting process to form the 130 mesh component will now be discussed in more detail. As mentioned above, the sock portion 131 has the general configuration of a sock. That is, the sock portion 131 may incorporate various features and structures of knitted fabric that are generally used in socks that are designed to cover the foot. The knitting process portion that forms the sock portion 131 is well known, therefore, in the knitting technique. In contrast to a conventional sock, however, the knitted component 130 includes the tongue portion 132. In order to make the tongue portion 132 with the sock portion 131, the general knitting process can proceed as follows: initially, the knitting machine makes a first circular sequence that forms a portion of the collar area 151 and transfers the first circular sequence to a disc that maintains the first circular sequence throughout the rest of the knitting process. Various other circular sequences that form portions of the collar area 151 can also be formed. In creating the tongue portion 132, the knitting machine can alternate to form each layer of mesh fabric 156 and 157. After the alternation is complete and the tongue portion 132 is formed, the knitting machine can proceed with the formation of one or more additional circular sequences that form portions of the collar area 151 and one of these additional circular sequences can be joined with the first circular sequence maintained on the disc. At that point, portions of the collar area 151 and tongue portion 132 are formed and the knitting process can proceed in a well-known manner to form the remainder of the sock portion 131. In reality, therefore, the knitting process for the component made in mesh 130 is similar to the conventional process for forming a sock, but includes additional alternating steps to form the tongue portion 132. [054] Many aspects of the knitting process discussed above can be performed using a conventional circular knitting machine. In order to facilitate some portions of the knitting process, however, the circular knitting machine can be modified to raise and lower the disk, which maintains the first sequence formed in the 130 mesh component. In addition, a blower can be used to guarantee that the knitted component 130 remains properly located within the circular knitting machine during the knitting process. [055] Based on the above discussion, a circular knitting process forms the knitted component 130. After the knitting process is complete, the knitted component 130 can be incorporated in the upper part 120. More particularly, the knitting component made of mesh 130 is located inside the component of cover 140 and extends from the front region of the foot 101 to the region of the heel 103. Furthermore, the component made of mesh 130 is oriented, such that the tongue portion 132 is located to extend over at least a portion of the length of the entry area 124. In configurations where the knitted component is attached to the cover component 140, sewing, adhesive bonding or thermal bonding can be used. [056] The invention is revealed above and in the accompanying figures with reference to a variety of configurations. The purpose served by the disclosure, however, is to present an example of the various characteristics and concepts related to the invention, not to limit the scope of the invention. One skilled in the relevant art will recognize that numerous variations and modifications can be made to the configurations described above without departing from the scope of the present invention, as defined by the appended claims.
