Description

Technical Field

[0001] This utility model relates to the field of shoe upper technology, specifically to a highly breathable and stable shoe upper and footwear products. Background Technology

[0002] The upper, as the part of footwear that directly wraps around the user's foot, has the core function of providing necessary protection, support, and comfort. In the field of athletic shoes, as users' demands for athletic performance and wearing experience continue to increase, upper design needs to strike a balance between two conflicting performance indicators: firstly, providing sufficient support and stability for the foot during high-speed, high-intensity exercise to prevent sports injuries; and secondly, keeping the foot dry and comfortable during prolonged exercise, i.e., possessing excellent breathability and heat dissipation. Current upper designs have not yet adequately resolved this technical contradiction. Utility Model Content

[0003] The purpose of this invention is to overcome the aforementioned defects or problems in the prior art and to provide a highly breathable and stable shoe upper and footwear product that achieves a good balance between support stability and breathability.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Technical Solution 1: A highly breathable and stable shoe upper, comprising: a base layer, which is a mesh fabric with perforations, and serves as the base of the shoe upper, defining an outer edge, a rear edge, a tongue edge, and a cuff edge on its outer perimeter; the outer edge is for attachment to the sole, the tongue edge is for forming a tongue opening, the cuff edge is for forming a cuff opening, and the rear edge is for joining with each other to enclose the cuff opening; and a reinforcing layer, comprising longitudinal reinforcing members and diagonal reinforcing members laid and connected to the outer surface of the base layer; the longitudinal reinforcing members comprising a plurality of longitudinal reinforcing yarns, the longitudinal reinforcing yarns extending from the rear edge or the cuff edge to the outer edge along the length direction of the base layer; the diagonal reinforcing members comprising a plurality of diagonal reinforcing yarns, the diagonal reinforcing yarns extending from the rear edge or the cuff edge to the outer edge at an incline relative to the length direction of the base layer; at least a portion of the diagonal reinforcing yarns intersect with the longitudinal reinforcing yarns to form a first cross knot.

[0006] Technical Solution 2 based on Technical Solution 1: Using a straight line extending along the length direction and passing through the midpoint of the width direction of the base layer as the reference line, in the oblique reinforcing member, each oblique reinforcing yarn has a tendency to be more inclined relative to the reference line the further away from the reference line it is.

[0007] Technical Solution 3 based on Technical Solution 2: At least some of the oblique reinforcing yarns intersect to form a second cross knot.

[0008] Technical Solution 4 based on Technical Solution 3: The longitudinal reinforcing member includes several longitudinal reinforcing units, each of the longitudinal reinforcing units includes at least two longitudinal reinforcing yarns, and the longitudinal reinforcing yarns belonging to the same longitudinal reinforcing unit cross at the outer edge to form a third cross knot, and are separated at the rear edge or shoe opening edge.

[0009] Technical Solution 5 based on Technical Solution 4: The oblique reinforcing member includes several oblique reinforcing units, each oblique reinforcing unit includes at least two oblique reinforcing yarns, and the oblique reinforcing yarns belonging to the same oblique reinforcing unit cross at the outer edge to form a fourth cross knot, and are separated at the rear edge or shoe opening edge.

[0010] Technical Solution Six based on Technical Solution Five: The oblique reinforcing yarn tends to have a higher arrangement density as it gets closer to the rear edge.

[0011] Technical solution seven based on technical solution six: also includes an edge layer; the edge layer continuously covers the outer surface of the base layer along the outer edge of the base layer, and covers the portions of each of the longitudinal reinforcing yarns and diagonal reinforcing yarns in the reinforcing layer near the outer edge.

[0012] Technical solution eight based on technical solution seven: the edge layer is made of thermoplastic polyurethane elastomer, the reinforcing layer is made of polyester yarn, and the base layer is made of jacquard mesh fabric of polyester composite yarn with added spandex.

[0013] Technical solution nine based on technical solution eight: also includes an inner layer; the inner layer covers the inner surface of the base layer and is made of polyester woven fabric.

[0014] In addition, the present invention also provides technical solution ten: a footwear product, which includes a sole and an upper as described in any one of technical solutions one to nine, the upper being attached to the sole.

[0015] As can be seen from the above description of this utility model, compared with the prior art, this utility model has the following beneficial effects:

[0016] Technical Solution 1 provides a highly breathable and stable upper that achieves a good balance between support stability and breathability. The fundamental problem with existing technologies lies in their design philosophy, which typically directly links the structural strength of the upper to the physical density or thickness of the material itself. Whether using heavy, low-breathability leather materials or high-density weaving in specific areas, the essence is to gain support by increasing material accumulation, which inevitably leads to blocked airflow channels, thus sacrificing breathability. This solution separates the support components from the breathable base, and through their synergistic cooperation, achieves excellent structural stability without compromising breathability.

[0017] First, this design uses a mesh fabric with perforations as the base layer. Because this base layer is perforated throughout, it provides maximized airflow channels across the entire surface area of ​​the upper. Unlike existing technologies that use large areas of non-porous materials or create localized high-density woven areas, this design ensures excellent overall breathability of the upper by using mesh fabric as the base layer. On top of this, the upper also features a reinforcing layer composed of longitudinal and diagonal reinforcing yarns, forming a skeletal network of linear components. While providing support, the reinforcing yarns occupy a very small physical area relative to the total area of ​​the base layer, allowing most of the mesh to remain intact and unobstructed. This avoids the problem in existing technologies where breathability must be sacrificed for enhanced support.

[0018] More importantly, the inclusion of longitudinal and diagonal reinforcing members in the reinforcement layer allows for excellent structural support and stability of the upper with a smaller amount of reinforcing yarn. The longitudinal reinforcing yarns, arranged along the length of the upper, provide the primary tensile strength, preventing excessive longitudinal deformation during push-off and ensuring effective force transmission. The diagonal reinforcing yarns, on the other hand, primarily resist lateral shear forces, providing crucial support and wrapping for the foot during lateral movement and preventing improper slippage within the shoe. The longitudinal and diagonal reinforcing yarns intersect to form a first cross knot. This first cross knot transforms the originally independent, unidirectionally stressed yarns into a mechanically interconnected and mutually supportive two-dimensional network. When the upper is subjected to external forces from any direction, the force is rapidly transferred from the individual stressed yarns through the cross knots and distributed throughout the entire reinforcement network, where multiple yarns in multiple directions share the load. This results in a lightweight skeletal network constructed with a small amount of yarn, while simultaneously generating excellent structural strength and stability.

[0019] In technical solution two, by setting each diagonal reinforcing yarn to have a tendency to be more inclined relative to the baseline as it moves further away, the support function of the reinforcing layer achieves a higher degree of match with the biomechanical needs of the foot. During movement, different areas of the foot have different functional requirements: the central area mainly bears the force transmission in the forward and backward directions, while the sides need to resist lateral and torsional forces more effectively. This inclined trend allows yarns closer to the center line with a smaller angle to more effectively cooperate with the longitudinal yarns to share the tensile force in the forward direction; while yarns arranged on the sides with a larger inclined angle can more effectively decompose and resist the impact force from the sides. This gradual angle layout from the center to the sides forms a functionally graded support structure, making the distribution of support force match the actual force distribution of the foot, thereby further improving the lateral stability and fit of the shoe upper without increasing material costs.

[0020] In technical solution three, the structural strength and synergy of the diagonal wrapping system are enhanced by forming second cross knots between at least some of the diagonal reinforcing yarns. The diagonal yarns not only intersect with the longitudinal yarns but also form internal cross connections. This structure transforms a group of relatively independent radial yarns connected only by a common starting point into a diagonal support subsystem with its own network characteristics. When the upper is subjected to torsional forces or localized lateral impacts, the force is not only transmitted longitudinally but also laterally dispersed within the diagonal subsystem through the second cross knots. This effectively improves the upper's adaptability to complex movements (such as sudden stops and changes of direction), enhances the upper's torsional rigidity, and ensures a more uniform coverage of the diagonal support force, avoiding localized deformation caused by excessive stress on a single yarn.

[0021] In technical solution four, the longitudinal reinforcing component is designed as a structure comprising several longitudinal reinforcing units, further optimizing the force transmission path and reducing stress concentration. Each longitudinal reinforcing unit consists of at least two yarns that cross near the outer edge of the sole and separate at the upper end near the shoe opening. This "Y" or "V" shaped modular structure can distribute the tensile force from the anchor point in a small area at the edge of the sole to two or more separate areas at the top. Conversely, the force from the top is also concentrated at the bottom intersection point. This structural design avoids the stress concentration problem caused by a single yarn running from beginning to end, especially reducing the localized tension of the yarn ends on the flexible base layer, and enhancing the durability of the bond between the reinforcing layer and the base layer.

[0022] In technical solution five, by designing the oblique reinforcing component as a structure containing several oblique reinforcing units, each oblique reinforcing unit also adopts a layout where the yarns cross at the edge of the sole and separate at the edge of the shoe opening. This allows the support force emanating from the key wrapping area of ​​the shoe opening to be transmitted and anchored to the edge of the sole more smoothly and dispersedly. This effectively improves the wrapping stability and support efficiency of the ankle and arch areas, making the oblique support system more stable in its response to resisting lateral forces, and the force distribution more uniform.

[0023] In technical solution six, by setting a trend where the density of the diagonal reinforcing yarns increases as they approach the rear edge, precise and targeted distribution of support is achieved. The rear of the foot, especially the ankle and heel areas, is the most critical area for stability control and injury prevention during exercise. Concentrating higher-density diagonal reinforcing yarns in this area significantly enhances ankle lockdown and heel support without increasing the overall weight of the upper. Simultaneously, the relatively lower yarn density in the forefoot area ensures that flexibility and breathability in this area are not compromised.

[0024] In technical solution seven, the reliability of anchoring the reinforcing yarn ends is solved by adding an edge layer, thus improving the overall durability of the upper. The yarn ends in the reinforcing layer need to be firmly fixed to the base layer to withstand tensile forces. The edge layer, along the outer edge of the base layer, covers the ends of all yarns. This structure serves a dual purpose: First, it provides a robust base with strength far exceeding that of the mesh base layer, firmly pressing all yarn ends together and effectively preventing the yarn ends from detaching from the mesh or tearing the base layer under high-strength tension. Second, the junction between the upper and the sole is the area with the most frequent wear; the continuous coverage of the edge layer provides additional protection for this high-wear area, significantly improving the lifespan of the upper.

[0025] In technical solution eight, the base layer uses polyester composite yarn with added spandex. The polyester ensures the strength and durability of the base, while the addition of spandex gives the base layer excellent elasticity, allowing it to actively conform to the foot's contours and provide a dynamic, wrapping feel. The reinforcing layer uses polyester yarn, utilizing the high tensile strength and low elongation of polyester to ensure stable and reliable support under stress without significant elongation. The edge layer uses thermoplastic polyurethane elastomer (TPU), leveraging TPU's excellent abrasion resistance, tear strength, and ease of thermoforming.

[0026] In technical solution nine, the addition of an inner lining layer improves the comfort of the shoe upper. The yarns of the reinforcing layer and the inner surface of the base layer mesh can cause direct friction against the skin. The inner lining layer, covering the inside of the base layer, provides a smooth, soft, and skin-friendly contact surface for the foot. This effectively isolates the foot from direct contact with the functional structural layers, reduces friction, and provides some moisture-wicking properties, thus maximizing comfort for extended wear while maintaining the shoe's strong functionality.

[0027] Technical solution ten provides a footwear product that uses the above-mentioned upper, thus having high breathability and strong stability. Attached Figure Description

[0042] Example

[0043] This invention relates to a footwear product comprising an upper and a sole. The sole can be made of materials conventional in the art, such as, but not limited to, rubber, ethylene-vinyl acetate copolymer (EVA), polyurethane (PU), thermoplastic polyurethane elastomer (TPU), or any combination of the above materials. In one specific embodiment, the sole may include a midsole for providing cushioning and support, and an outsole for providing abrasion resistance and slip resistance. The midsole may be made of foamed materials such as EVA or PU, and the outsole may be made of abrasion-resistant rubber. It should be understood that the specific materials and structure of the sole are conventional designs well known to those skilled in the art and are not the focus of this invention. The core innovation of this invention lies in the specific structure of the upper, which provides excellent support and stability while also ensuring excellent breathability and comfort. The upper structure in this embodiment will be described in detail below with reference to the accompanying drawings.

[0044] Reference Figure 1 and Figure 2 The upper of this footwear product consists of an inner lining layer 40, a base layer 10, a reinforcing layer 20, and an edge layer 30, from the inside out.

[0045] The base layer 10 is a mesh fabric with perforations 11, and serves as the base of the shoe upper. Its outer edge is defined by an outer edge 12, a rear edge 13, a tongue edge 14, and a shoe opening edge 15. The outer edge 12 is used to attach to the sole, the tongue edge 14 is used to form a tongue opening 16, the shoe opening edge 15 is used to form a shoe opening opening 17, and the rear edge 13 is used to connect with each other to enclose the shoe opening opening 17.

[0046] Specifically, refer to Figure 1 and Figure 2 The base layer 10 uses a mesh fabric with perforations 11 as raw material, and it is a single fabric component manufactured using an integral molding process. As a preferred embodiment, the base layer 10 uses a jacquard mesh fabric made of polyester composite yarn with added spandex. The preparation process involves the following steps: First, a functional composite yarn is selected, for example, using polyester as the main material to ensure structural strength and durability, and blended or coated with a certain proportion of spandex fibers to provide excellent elasticity and fit. Then, the composite yarn is woven using a computer jacquard knitting process. This process can directly weave a mesh structure 11 with a specific distribution and aperture on the same piece of fabric according to a preset program. The product of this step is a two-dimensional, planar shoe upper fabric. Finally, the shoe upper fabric is precisely trimmed by cutting or laser cutting to remove excess material, thereby obtaining the desired result. Figure 1 The base layer 10 shown has a specific unfolded shape.

[0047] like Figure 1As shown, the base layer 10, produced through the above processes, forms multiple functional edges around its periphery. The outer edge 12 is the lower contour boundary of the entire base layer 10, and this edge is connected and fixed to the sole in subsequent molding processes through methods such as lasting and bonding. The tongue edge 14 and the shoe opening edge 15 together constitute the upper opening of the shoe upper. Among them, the shoe opening edge 15 is the main opening contour for the user's foot to enter, while the tongue edge 14 defines the opening for installing independent shoe tongue components. The rear edges 13 refer to the two corresponding edges at the very end of the base layer 10 in its planar unfolded state. During the three-dimensional stitching of the shoe upper, these two rear edges 13 will align and connect with each other through stitching or other means, thereby forming a three-dimensional cup-shaped heel structure that wraps around the user's heel, and finally forming a complete shoe opening.

[0048] Reference Figure 1 and Figure 3 The reinforcing layer 20 includes longitudinal reinforcing members 21 and diagonal reinforcing members 22 laid and connected to the outer surface of the base layer 10; the longitudinal reinforcing member 21 includes a plurality of longitudinal reinforcing yarns 211, which extend from the rear edge 13 or the shoe opening edge 15 to the outer edge 12 along the length direction of the base layer 10; the diagonal reinforcing member 22 includes a plurality of diagonal reinforcing yarns 221, which extend from the rear edge 13 or the shoe opening edge 15 to the outer edge 12 at an angle relative to the length direction of the base layer 10; at least a portion of the diagonal reinforcing yarns 221 intersect with the longitudinal reinforcing yarns 211 to form a first cross knot 23.

[0049] Specifically, the longitudinal reinforcing member 21 and the diagonal reinforcing member 22 in the reinforcing layer 20 are both formed by laying reinforcing yarn on the outer surface of the base layer 10. The reinforcing layer 20 is manufactured using computer numerical control (CNC) embroidery. During manufacturing, the pre-formed base layer 10 is first laid flat and fixed on the worktable of the embroidery machine. Then, a high-strength, low-elongation yarn, such as polyester industrial filament, is used as the reinforcing yarn. According to a pre-designed digital path file, the embroidery machine controls the embroidery needle to directly and firmly sew the reinforcing yarn onto the outer surface of the base layer 10 with a set stitch, thereby integrally forming the longitudinal reinforcing member 21 and the diagonal reinforcing member 22. This process ensures a tight bond between the reinforcing layer 20 and the base layer 10 without the need for adhesives. Furthermore, because the reinforcing members are linear, they retain the mesh 11 of the base layer 10 to the maximum extent, thus ensuring excellent breathability. Structurally, refer to... Figure 1In the overall view, the reinforcing layer 20 forms a skeletal network laid on the base layer 10. The reinforcing layer 20 mainly covers the two sides and the rear area of ​​the base layer 10 in the width direction, while the area corresponding to the toe is not reinforced. The longitudinal reinforcing members 21 include several longitudinal reinforcing yarns 211, which are reinforcing yarns in the reinforcing layer 20 that extend approximately along the length of the shoe upper. These longitudinal reinforcing yarns 211 extend from the rear area to the front area of ​​the base layer 10, thus forming a reinforcing skeleton connecting the front and rear areas of the base layer 10. The diagonal reinforcing members 22 include several diagonal reinforcing yarns 221, which are reinforcing yarns in the reinforcing layer 20 with a large angle of inclination and mostly distributed in the rear area of ​​the base layer 10. The reinforcing skeleton formed by the diagonal reinforcing yarns 221 is mainly used to reinforce the rear area of ​​the shoe upper.

[0050] Among them, reference Figure 1 Part of the longitudinal reinforcing yarn 211 is connected at both ends to the front and rear edges 13 of the base layer 10, and part of the longitudinal reinforcing yarn 211 is connected at both ends to the front edge and the shoe opening edge 15 of the base layer 10. The front ends of the longitudinal reinforcing yarn 211 are all connected to the portion of the front edge near the toe. Part of the diagonal reinforcing yarn 221 is connected at both ends to the front and rear edges 13 of the base layer 10, and part of the diagonal reinforcing yarn 221 is connected at both ends to the front edge and the shoe opening edge 15 of the base layer 10. The front ends of the diagonal reinforcing yarn 221 are all connected to the portion of the front edge near the arch and heel. Within this, refer to... Figure 3 The longitudinal reinforcing yarns 211 and the diagonal reinforcing yarns 221 intersect to form a first cross knot 23. A cross knot is a structure formed at the intersection of yarns extending in different directions within the reinforcing layer 20, where the two yarns are connected to each other. Because the longitudinal reinforcing yarn 211 has a relatively long span, one longitudinal reinforcing yarn 211 can intersect with multiple diagonal reinforcing yarns 221 to form a first cross knot 23; similarly, one diagonal reinforcing yarn 221 can also intersect with multiple longitudinal reinforcing yarns 211 to form a first cross knot 23.

[0051] Reference Figure 1Using a straight line extending along the length direction and passing through the midpoint of the width direction of the base layer 10 as a baseline, in the oblique reinforcing member 22, each oblique reinforcing yarn 221 tends to be more inclined relative to the baseline the further away from it. Specifically, a baseline is defined, and relative to this baseline, each oblique reinforcing yarn 221 macroscopically presents a non-uniform radial fan-shaped layout with the rear area of ​​the shoe opening 17 as the origin. The oblique reinforcing yarn 221 near the center line of the shoe upper has a smaller angle with the length direction of the shoe upper, almost perpendicular; as the arrangement position of the oblique reinforcing yarn 221 moves along the outer edge 12 to the sides and rear, the inclination angle of the oblique reinforcing yarn 221 increases significantly, and the angle with the length direction becomes larger and larger. This gradual angle layout from the center to the sides forms a functionally graded support structure, making the distribution of support force match the actual force distribution of the foot, thereby further improving the lateral stability and fit of the shoe upper without increasing any material costs.

[0052] Furthermore, referring to Figure 3 At least some of the diagonal reinforcing yarns 221 intersect to form a second cross knot 24. Specifically, the second cross knot 24 refers to the intersection point formed by one diagonal reinforcing yarn 221 and another diagonal reinforcing yarn along its extension path. Morphologically, this cross structure further divides the large area enclosed by adjacent diagonal reinforcing yarns 221 into smaller triangular or polygonal grids with yarns as boundaries. This structure transforms a group of relatively independent radial yarns connected only by a common starting point into a diagonal support subsystem that also possesses network characteristics. When the upper is subjected to torsional force or local lateral impact, the force is not only transmitted longitudinally but also laterally dispersed within the diagonal subsystem through the second cross knot 24. This effectively improves the upper's adaptability to complex movements (such as sudden stops and changes of direction), enhances the upper's torsional rigidity, and ensures a more uniform coverage of the diagonal support force, avoiding localized deformation caused by excessive stress on a single yarn.

[0053] Reference Figure 1 and Figure 3 The longitudinal reinforcing member 21 includes several longitudinal reinforcing units 25. Each longitudinal reinforcing unit 25 includes at least two longitudinal reinforcing yarns 211. The longitudinal reinforcing yarns 211 belonging to the same longitudinal reinforcing unit 25 cross at the outer edge 12 to form a third cross knot 26, and are separated at the rear edge 13 or the shoe opening edge 15. Specifically, structurally, each longitudinal reinforcing unit 25 presents an inverted "V" shape. Figure 1As shown, the two or more longitudinal reinforcing yarns 211 constituting this unit are separated from each other and maintain a certain distance at their rear ends, i.e., near the edge 15 of the shoe opening, forming two forked arms in a "V" shape. These yarns then move forward along the length direction and gradually converge, finally meeting and crossing at the same point at their front end, i.e., near the outer edge 12, forming a third cross knot 26. This structural design avoids the stress concentration problem caused by a single yarn from beginning to end, especially reducing the local tension of the yarn ends on the flexible base layer 10, and enhancing the durability of the bond between the reinforcing layer 20 and the base layer 10.

[0054] Reference Figure 1 and Figure 3 The oblique reinforcing member 22 includes several oblique reinforcing units 27. Each oblique reinforcing unit 27 includes at least two oblique reinforcing yarns 221. The oblique reinforcing yarns 221 belonging to the same oblique reinforcing unit 27 cross at the outer edge 12 to form a fourth cross knot 28, and are separated at the rear edge 13 or the shoe opening edge 15. Specifically, structurally, each oblique reinforcing unit 27 presents an inclined, inverted "V" shape. Figure 3 As shown, the two or more diagonal reinforcing yarns 221 constituting this unit are separated from each other and maintain a certain distance at their rear end, i.e., near the edge 15 of the shoe opening, forming two forked arms in a "V" shape. These yarns then move forward along an inclined path and gradually converge, finally meeting and crossing at the same point at their front end, i.e., near the outer edge 12, forming a fourth cross knot 28. This structure effectively improves the stability and support efficiency of the ankle and arch areas, making the diagonal support system more stable in its response to lateral forces and the force distribution more uniform.

[0055] Among them, the diagonal reinforcing yarns 221 tend to have a higher density as they approach the rear edge 13. Specifically, this density trend manifests in the upper structure as a gradient layout from dense to sparse from back to front. (Refer to...) Figure 1 In the area closest to the rear edge 13, the spacing between the diagonal reinforcing yarns 221 is the smallest, and the number of yarns per unit area is the largest. However, as the position moves along the length towards the forefoot area, the CEO spacing between the yarns increases significantly, and the distribution becomes sparser. Concentrating the higher density of the diagonal reinforcing yarns 221 on the rear side can greatly enhance the ankle lockdown and heel support without increasing the overall weight of the upper. At the same time, the relatively lower yarn density in the forefoot area ensures that the flexibility and breathability of this area are not affected.

[0056] In addition, refer to Figure 2The edge layer 30 in the upper continuously covers the outer surface of the base layer 10 along its outer edge 12, and covers the portions of the longitudinal reinforcing yarns 211 and diagonal reinforcing yarns 221 in the reinforcing layer 20 near the outer edge 12. Specifically, the edge layer 30 is typically a thin film made of a highly abrasion-resistant and high-strength material such as thermoplastic polyurethane (TPU), which is fused to the outer surface of the base layer 10 via a hot-pressing process. Structurally, the edge layer 30 is a continuous strip-like structure precisely distributed along the entire outer edge 12 of the base layer 10. Its core function is to structurally anchor and protect the ends of the reinforcing layer 20. Figure 1 As shown, the edge layer 30 covers the portion of all longitudinal reinforcing yarns 211 and diagonal reinforcing yarns 221 near the outer edge 12 of the base layer 10, including the third cross knot 26 and the fourth cross knot 28, which serve as their convergence points. The edge layer 30 serves a dual purpose: firstly, it provides a robust base with significantly higher strength than the mesh base layer 10, firmly pressing the ends of all yarns together and effectively preventing the yarn ends from detaching from the mesh or tearing the base layer 10 under high-strength tension. Secondly, the junction between the upper and the sole is the area most frequently worn; the continuous coverage of the edge layer 30 provides additional protection to this high-wear area, significantly improving the lifespan of the upper.

[0057] Reference Figure 2 The inner lining layer 40 of the upper covers the inner surface of the base layer 10 and is made of polyester woven fabric. Specifically, the inner lining layer 40 is structurally the innermost layer of the entire upper, and it is fixed to the inner surface of the base layer 10 by processes such as sewing, serving as the interface that directly contacts the user's foot or socks. The main function of the inner lining layer 40 is to enhance wearing comfort and protect the internal structure. The yarn of the reinforcing layer 20 and the inner surface of the mesh fabric of the base layer 10 may cause direct friction against the skin. The inner lining layer 40, covering the inside of the base layer 10, provides the foot with a smooth, soft, and skin-friendly contact surface. This effectively isolates the foot from direct contact with the functional structural layers, reduces friction, and provides some moisture-wicking properties, thus maximizing comfort for extended wear while achieving the strong functionality of the upper.

[0058] In the footwear products and uppers involved in this embodiment, the upper achieves a good balance between support stability and breathability. Firstly, this solution uses a mesh fabric with perforations 11 as the base layer 10. Because the base layer 10 is covered with perforations 11, it provides maximized air convection channels across the entire surface area of ​​the upper. Unlike existing technologies that use large areas of non-porous materials or form localized high-density woven areas, this solution ensures good overall breathability of the upper by using the mesh fabric as the base layer 10. Furthermore, the upper also features a reinforcing layer 20 composed of longitudinal and diagonal reinforcing yarns 221. This reinforcing layer 20 is a skeletal network formed by laying down linear components. While providing support, the reinforcing yarns occupy a very small physical area relative to the total area of ​​the base layer 10, allowing most of the perforations 11 to be fully preserved without being obstructed. This avoids the problem in existing technologies where breathability must be sacrificed for enhanced support. More importantly, the longitudinal reinforcing members 21 and diagonal reinforcing members 22 in the reinforcing layer 20 allow for excellent structural support and stability of the upper with fewer reinforcing yarns. The longitudinal reinforcing yarns 211, arranged along the length of the upper, provide the upper with the main tensile strength, preventing excessive longitudinal deformation when the user pushes off the ground and exerts force, ensuring effective force transmission. The diagonal reinforcing yarns 221 are mainly used to resist lateral shear forces, providing crucial wrapping and support for the foot during lateral movement, preventing improper slippage of the foot inside the shoe. The longitudinal reinforcing yarns 211 and diagonal reinforcing yarns 221 intersect to form a first cross knot 23. The first cross knot 23 transforms the originally independent, unidirectionally stressed yarns into a mechanically interconnected and mutually supportive two-dimensional network structure. When the upper is subjected to external forces from any direction, the force is quickly transmitted from the individual stressed yarns through the cross knots and distributed throughout the entire reinforcing network, where it is borne by multiple yarns in multiple directions. This allows for the creation of a lightweight skeletal network using a small amount of yarn, while simultaneously producing excellent structural strength and stability.
