Description

Technical Field

[0001] This invention relates to the field of footwear technology, and more specifically to one-piece shoe plates, three-dimensional shoe uppers, and shoe upper manufacturing processes. Background Technology

[0002] Traditional shoe uppers are three-dimensional, but one-piece uppers cannot form a three-dimensional structure. Therefore, most current shoe uppers use at least two woven panels sewn together to form a three-dimensional structure. However, to ensure aesthetics and practical needs, a reverse interface structure is formed between the two woven panels. This reverse interface structure refers to a hidden seam or an inward folded seam. For example, Chinese patent CN118716730A, "An Easy-to-Wear and Take-Off Sports Shoe," includes an interconnected upper body and a sole. The upper body includes a first woven panel and a second woven panel sewn together, ...; wherein the first end of the second woven panel is sewn to the first woven panel at the rear of the shoe, and the second end of the second woven panel is sewn to the first woven panel at the inside of the shoe. However, with this reverse interface structure, athletes are prone to feeling the foreign object from the reverse interface, and it is easy to cause friction with the skin of the foot during wear. Long-term use may lead to decreased comfort and even problems such as blisters. Furthermore, insufficient strength at the seam may affect the overall durability of the upper.

[0003] In view of this, this application has conducted in-depth research on this basis, resulting in this case. Summary of the Invention

[0004] The purpose of this invention is to provide a one-piece three-dimensional shoe upper that can achieve a seamless shoe upper design while ensuring a good fit, comfort, and durability.

[0005] Another object of the present invention is to provide a one-piece and seamless three-dimensional shoe plate.

[0006] Another objective of this invention is to provide a one-piece three-dimensional shoe upper manufacturing process that is simple and can produce a seamless one-piece shoe upper.

[0007] To achieve the above objectives, the solution of the present invention is: A one-piece three-dimensional shoe upper includes a shoe upper body, which includes a one-piece outer shoe upper layer and an inner shoe upper layer attached to the inside of the outer shoe upper layer. The inner shoe upper layer is a one-piece sock-like structure formed by fly-knitting. Two heel counterstrips extend from the rear side of the outer shoe upper layer. The outer shoe upper layer forms a heel counter through the cooperation of the two heel counterstrips, and forms a shoe opening and an open opening. An ankle counterstrip is connected to the outer shoe upper layer. The ankle counterstrip is located at a corresponding position of the open opening, and the ankle counterstrip is detachably connected to the inner shoe upper layer.

[0008] The mating sides of the two rear connecting straps are directly and fixedly connected together, or the mating sides of the two rear connecting straps are connected together in a manner that allows for adjustment of the circumference of the rear side.

[0009] The mating sides of the two back connecting strips are heat-pressed, bonded, or sewn together; or, the mating sides of the two back connecting strips are respectively provided with first Velcro fasteners that bond with each other; or, one of the mating sides is provided with a magnetic attractant with a first tooth, and the other mating side is provided with a magnetic attractant with a second tooth, the first tooth and the second tooth interlocking with each other, and the two magnetic attractants attracting each other.

[0010] The ankle connecting strap is provided with a second Velcro with a hook-and-loop surface, and the outer side of the inner shoe upper is provided with a second Velcro with a fleece surface corresponding to the opening; or, the ankle connecting strap is provided with a second Velcro with a fleece surface, and the outer side of the inner shoe upper is provided with a second Velcro with a hook-and-loop surface corresponding to the opening; the two second Velcros are glued together.

[0011] The outer shoe upper is also integrally connected with a foot instep connecting strap, which is located at the corresponding position of the opening, in front of the ankle connecting strap, and is detachably connected to the inner shoe upper.

[0012] The instep connecting strap is provided with a third Velcro with a hook-and-loop surface, and the outer side of the inner shoe upper layer is provided with a third Velcro with a fleece surface corresponding to the opening; or, the instep connecting strap is provided with a third Velcro with a fleece surface, and the outer side of the inner shoe upper layer is provided with a third Velcro with a hook-and-loop surface corresponding to the opening; the two third Velcros are glued together.

[0013] An integrated shoe plate includes an integrated shoe panel, with two heel counter straps extending from the rear side of the shoe panel. The shoe panel has an opening, which, when the two heel counter straps are engaged, forms an interconnected shoe opening and an open opening. The open opening is located on the front side of the shoe opening. The shoe panel is connected to a front ankle strap, which is located at a corresponding position of the open opening.

[0014] Both rear connecting strips have mating sides on one side and opposing sides on the other side, with connection positions provided on the mating sides of the two rear connecting strips; or, the mating sides of the two rear connecting strips have mating areas that cooperate with each other.

[0015] The shoe panel is also integrally connected with a foot instep connecting strap, which is located at the corresponding position of the opening and is located in front of the ankle connecting strap. The inner side of the foot instep connecting strap is provided with a Velcro area.

[0016] A manufacturing process for a one-piece three-dimensional shoe upper includes the following steps: Step 1: Inner shoe upper layer weaving. The first yarn is woven into an integral inner shoe upper layer using a fly knitting method. This inner shoe upper layer has a sock-like structure. Step 2: Outer shoe upper layer weaving. Using a weaving machine in conjunction with the one-piece shoe plate, the second yarn is woven into an one-piece outer shoe upper layer. Step 3: Inner and outer shoe upper layers are laminated. The inner shoe upper layer obtained in Step 1 and the outer shoe upper layer obtained in Step 2 are respectively formed into a three-dimensional structure using a shoe last. The outer shoe upper layer is attached to the outer side of the inner shoe upper layer. Then, the inner shoe upper layer and the outer shoe upper layer are laminated together to obtain a three-dimensional shoe upper.

[0017] An additional step is added between step 2 and step 3, wherein a first Velcro fastener that cooperates with each other is fixed to the Velcro area of ​​the two heel connecting straps, a second Velcro fastener is fixed to the Velcro area of ​​the ankle connecting strap, a third Velcro fastener is fixed to the Velcro area of ​​the instep connecting strap, and another second Velcro fastener that cooperates with the second Velcro fastener and another third Velcro fastener that cooperates with the third Velcro fastener are fixed to the outer side of the inner shoe upper.

[0018] In step 3, the outer shoe upper layer and the inner shoe upper layer are bonded together by a high-temperature integrated three-dimensional seamless press.

[0019] With the above structure, the one-piece three-dimensional shoe upper of the present invention has the following beneficial effects: 1. This invention employs the cooperation of an outer shoe upper layer and an inner shoe upper layer, with the ankle connecting strap on the outer shoe upper layer connecting to the inner shoe upper layer. Combined with the two heel connecting straps on the outer shoe upper layer, the outer shoe upper layer forms a three-dimensional shoe upper behind the two heel connecting straps. The one-piece design of the outer shoe upper layer and the inner shoe upper layer, i.e., the seamless structure design, effectively avoids the reverse interface structure (seam) problem caused by the stitching of multiple woven surfaces in traditional shoe uppers. This eliminates the foreign body sensation on the athlete's feet, reduces discomfort caused by friction, improves wearing comfort, and avoids the defect of easy breakage at the seams, extending the service life of the shoe upper. At the same time, this invention also has good wrapping and elasticity.

[0020] 2. In this invention, the inner shoe upper layer is an integrated sock-like structure, which can closely fit the foot, providing good wrapping and elasticity, and further improving the comfort and stability of wearing.

[0021] 3. In this invention, the ankle connecting strap and the inner shoe upper are connected by a second Velcro closure, and the instep connecting strap and the inner shoe upper are connected by a third Velcro closure. This allows for easy adjustment according to the width of the foot, enabling the instep portion to be adjusted even without shoelaces, ensuring the shoe upper wraps around the foot. Furthermore, the instep connecting strap further enhances the fixation between the shoe upper and the foot, preventing the shoe upper from shifting during exercise and ensuring safety during activity.

[0022] 4. The invention employs a combination of two back straps to adjust the circumference of the back part, allowing the upper to better fit different ankle sizes and enhancing the versatility and practicality of the upper.

[0023] With the above structure, the one-piece shoe plate of the present invention has the following beneficial effects: The present invention achieves a seamless design of the shoe plate through the one-piece molding design. Combined with the structural design of the heel connecting strap, ankle connecting strap and instep connecting strap on the shoe plate, it can ensure that the outer shoe upper layer is woven into a one-piece surface layer and ensure the molding quality of the three-dimensional shoe upper.

[0024] After adopting the above manufacturing process, the present invention has the following beneficial effects: the shoe upper can be formed into an integrated three-dimensional shoe upper, and the shoe upper has a seamless structure, which ensures the three-dimensional molding effect of the shoe upper and the tight bonding between each layer. The produced three-dimensional shoe upper has good structural stability and appearance consistency, and the shoe upper has good coverage and comfort. Moreover, the manufacturing process is simple and convenient, which improves production efficiency. Attached Figure Description

Detailed Implementation

[0032] To further explain the technical solution of the present invention, the present invention will be described in detail below through specific embodiments.

[0033] Example 1 One-piece three-dimensional upper, such as Figure 1 As shown - Figure 3 As shown, the shoe includes an upper body 100. For ease of description, in this embodiment, the side of the upper body 100 facing the toe is considered the front, and the opposite side is considered the back. The side that contacts the human foot is considered the inside, and the opposite side is considered the outside. The direction that is horizontal and perpendicular to the front and back is considered the left and right direction. The upper body 100 includes an outer upper layer 1 and an inner upper layer 2. The outer upper layer 1 is attached to the outer side of the inner upper layer 2. The two are connected together in a conventional way, such as high-temperature hot pressing or bonding.

[0034] The aforementioned inner shoe upper layer 2 is a one-piece sock-like structure made of conventional flyknit. The outer shoe upper layer 1 is one-piece, and two heel connecting straps 3 extend from the rear side of the outer shoe upper layer 1. The outer shoe upper layer 1 forms a heel part 11 through the cooperation of the two heel connecting straps 3, and forms a shoe opening 12 and an open opening 12. The outer shoe upper layer 1 is also connected to an ankle connecting strap 4, which is close to the front of the human ankle and is located at the corresponding position of the open opening 13. The ankle connecting strap 4 is detachably connected to the inner shoe upper layer 2.

[0035] Furthermore, the aforementioned inner shoe upper layer 2 is designated as an elastic region 21 corresponding to the front of the ankle, while the other areas of the non-elastic region 21 in the inner shoe upper layer 2 are non-elastic regions 22. In this embodiment, the elastic region 21 is knitted using elastic yarn, and the non-elastic region 22 is knitted using non-elastic yarn. That is, the inner shoe upper layer 2 is knitted using conventional elastic and non-elastic yarns in one piece, employing a conventional wrapping and blending method. For example, the elastic region 21 can be made of elastic yarn formed by hot-melt yarn wrapping monofilaments, and the non-elastic region 22 can be made of non-elastic yarn formed by monofilaments and multifilaments, thereby making the inner shoe upper layer 2 lighter, more breathable, and stronger. In addition, in this embodiment, the inner shoe upper layer 2 can be knitted into a sock tube structure using commercially available computerized knitting equipment (such as a sock knitting machine) for producing seamless one-piece molded socks.

[0036] Furthermore, in this embodiment, the aforementioned outer shoe upper layer 1 can be made using a commercially available knitting machine, such as a circular knitting machine or a warp knitting machine, and the outer shoe upper layer 1 can be made of conventional yarns, such as monofilaments or multifilaments made of high-strength, tough, and lightweight materials like ultra-fine twisted palm fiber and ultra-high molecular weight polyethylene.

[0037] To elaborate further, for ease of description, the side where the two back connecting straps 3 cooperate is called the cooperating side, and the other side is called the diverging side. The cooperating sides of the two back connecting straps 3 can be fixedly connected to each other, and the two can be connected together by conventional methods such as sewing, heat pressing or bonding.

[0038] As a preferred embodiment, the mating sides of the two rear connecting straps 3 can also be connected together in a manner that allows for adjustment of the circumference of the rear part 11, so as to facilitate flexible adjustment according to the shape of the human foot.

[0039] Specifically, the mating side of the two rear connecting belts 3 can be adjusted in various ways, as described below.

[0040] In the first structure, a first Velcro closure is provided on the mating side of each of the two heel connecting straps 3. One heel connecting strap 3 is longer than the other. The mating side of the longer heel connecting strap 3 has a first Velcro closure 31 with a hook-and-loop surface, extending from the free end of the mating side to the other end. The mating side of the other heel connecting strap 3 has a first Velcro closure 32 with a fleece surface, extending from the free end of its mating side to the other end. The two first Velcro closures are bonded together. Thus, the circumference of the heel counter 11 can be changed by adjusting the bonding position of the two first Velcro closures, thereby adapting to different ankle circumferences. Preferably, the length of the first Velcro closure 31 with the hook-and-loop surface is greater than that of the first Velcro closure 31 with the fleece surface to ensure the overall aesthetics of the shoe upper.

[0041] It should be noted that the mating side of the two rear connecting straps 3 can be set to have either a hooked or a fleece-like first Velcro closure, depending on the actual situation, and is not limited to the above arrangement.

[0042] In the second structure, magnetic components are fixedly connected to the mating sides of the two rear connecting straps 3. In this embodiment, both magnetic components are magnetic plates 33, which are conventionally available on the market. The two magnetic plates 33 attract each other to connect the two rear connecting straps 3. Preferably, as shown in the example... Figure 4 As shown, one of the magnetic absorbing pieces 33 has a first locking tooth 331 integrally connected to its mating side, and the other magnetic absorbing piece 33 has a second locking tooth 332 integrally connected to its mating side. The teeth of the first locking tooth 331 and the second locking tooth 332 are arranged sequentially along the length of the back panel connecting strap, and the first locking tooth 331 and the second locking tooth 332 interlock with each other to increase friction and ensure that the two back panel connecting straps 3 are not easily loosened. In this way, the two back panel connecting straps 3 achieve adjustment of the circumference of the back panel 11 through the interlocking of the locking teeth and the attraction of the two magnetic pieces. This structure can not only ensure the stability of the connection, but also easily adapt to different ankle circumferences.

[0043] Furthermore, the detachable connection between the ankle-to-toe connecting strap 4 and the inner shoe upper layer 2 also adopts a Velcro structure. Specifically, the ankle-to-toe connecting strap 4 is integrally connected to the left or right side of the outer shoe upper layer 1 corresponding to the opening 13. In this embodiment, the ankle-to-toe connecting strap 4 is located on the left side of the outer shoe upper layer 1 as an example. The inner side of the ankle-to-toe connecting strap 4 is provided with a second Velcro 41 with a fuzzy surface. The second Velcro 41 extends from the free end of the ankle-to-toe connecting strap 4 to the other end. The outer side of the inner shoe upper layer 2 is provided with a second Velcro 42 with a hook-and-loop surface. The second Velcro 42 is located on the right side of the inner shoe upper layer 2 near the outer shoe upper layer 1. The two second Velcro 41 are bonded together. In this way, the inner shoe upper layer 2 and the ankle-to-toe connecting strap 4 are fixed by adhesive. Disassembly is simple and quick because it can be easily and quickly done by simply tearing it apart.

[0044] As a preferred embodiment, to further enhance the stability of the upper body 100, the outer upper layer 1 is also integrally connected with a foot instep connecting strap 5. This foot instep connecting strap is located in front of the ankle connecting strap 4 and is positioned corresponding to the opening 13. The foot instep connecting strap 5 is detachably connected to the inner upper layer 2. Specifically, the foot instep connecting strap 5 and the inner upper layer 2 are connected by a third Velcro fastener. The inner side of the foot instep connecting strap 5 is provided with a third Velcro fastener 51 with a fleece surface, and the outer side of the inner upper layer 2 is provided with a third Velcro fastener 52 with a hook-and-loop fastener. The two third Velcro fasteners are glued together. Preferably, the third Velcro fastener 52 with the hook-and-loop fastener is close to the right side of the outer upper layer 1, and the foot instep connecting strap 5 is integrally connected to the left side of the outer upper layer 1 corresponding to the opening 13, so that the foot instep connecting strap 5 and the ankle connecting strap 4 are arranged crosswise to make the upper body fit more tightly. In this way, by adjusting the position of the instep connecting strap 5, it can adapt to different instep widths, ensuring that the shoe upper fits the foot tightly during exercise and preventing loosening or displacement.

[0045] Furthermore, the aforementioned foot instep connecting strap 5 also has a hollowed-out section 53, which further makes the shoe upper body 100 thinner and more breathable.

[0046] It is worth mentioning that in this embodiment, each Velcro fastener can be set using conventional hot pressing, sewing, or one-piece weaving methods.

[0047] In practical use, by adjusting the bonding positions of the two heel counter connecting straps 3 and the bonding positions of the Velcro on the ankle connecting strap 4 and the instep connecting strap 5 to the Velcro on the inner upper layer 2, the fit and tightness of the upper body 100 can be flexibly adjusted to adapt to the foot shape characteristics of different users and improve the wearing experience. For example, when the user's feet are relatively slender, the two heel counter connecting straps 3 can be adjusted to a smaller circumference of the heel counter 11, while the ankle connecting strap 4 and the instep connecting strap 5 can be tightened and fixed inwards, so that the upper body 100 fits the foot closely. When the feet are slightly wider or a more relaxed wearing experience is needed, the connecting straps can be loosened appropriately to increase the space inside the shoe. This multi-part adjustable design effectively enhances the versatility and adaptability of the one-piece three-dimensional upper, meeting the wearing needs of different scenarios.

[0048] This embodiment presents a one-piece three-dimensional upper. Compared to the traditional upper body 100 formed by two woven panels, it fundamentally eliminates the reverse interface structure caused by stitching multiple woven panels through the one-piece design of the outer upper layer 1 and the inner upper layer 2. This avoids the foreign object feeling and friction problems caused by traditional seams. Furthermore, as a one-piece structure, the outer upper layer 1 does not need to form a three-dimensional contour by splicing multiple woven panels. Instead, it utilizes the cooperation of the heel counter connecting strap 3, the ankle connecting strap 4, and the instep connecting strap 5 to achieve the shaping and size adjustment of the three-dimensional upper while maintaining a seamless overall design. The inner upper layer 2 adopts a one-piece sock-like structure, which has good elasticity and fit. Its tight combination with the outer upper layer 1 further enhances the shoe's wrapping effect on the foot. This design not only improves wearing comfort and reduces the relative slippage between the foot and the upper during exercise, but also enhances the overall strength of the upper due to the seamless structure, reducing the risk of breakage at the seams and thus extending the service life of the upper.

[0049] Furthermore, the connecting straps are detachable, making the process of putting on and taking off the shoes more convenient, and allowing for personalized adjustments according to different foot shapes, thus balancing practicality and adaptability.

[0050] Example 2 This embodiment describes an integrated shoe plate, which is used to weave the outer shoe upper layer 1 of the integrated three-dimensional shoe upper described in Embodiment 1 using a conventional weaving machine.

[0051] like Figure 5 As shown, the one-piece shoe plate includes a shoe panel 200, which is a one-piece structure. Two heel connecting straps 3 extend from the rear side of the shoe panel 200, and the shoe panel 200 has a rearwardly extending opening. This opening can form a shoe opening 12 and an open opening 13 that are interconnected when the two heel connecting straps 3 are engaged. The open opening 13 is located on the front side of the shoe opening 12. The shoe panel 200 is also connected to an ankle connecting strap 4, which extends along the width direction of the shoe panel 200 and is located at the corresponding position of the open opening 13. Preferably, in this embodiment, the left end of the ankle connecting strap 4 is integrally connected to the left side of the shoe panel 200 corresponding to the open opening 13. Then, the right end of the ankle connecting strap 4 extends to the right side of the shoe panel 200 corresponding to the open opening 13. That is, the length direction of the ankle connecting strap 4 is distributed along the left and right directions of the shoe panel 200 at the open opening 13.

[0052] Specifically, the two heel connecting straps 3 in the shoe panel 200 have connection positions or mating areas on their mating sides. These mating areas can be Velcro areas or magnetic areas. The connection structure of the two heel connecting straps 3 adopts the same connection method as that in Embodiment 1. Thus, when the two are mated by the first Velcro, the mating area is the Velcro area, i.e., the mating area is used for the subsequent Velcro installation. When the two are mated by the structure of the magnetic piece and the locking teeth, the mating area is the magnetic area, i.e., the mating area is used for the subsequent magnetic piece installation. When the two are connected together by conventional methods such as sewing, heat pressing, or gluing, the connection position is the position for subsequent conventional connection.

[0053] Furthermore, the aforementioned shoe panel 200 is also integrally connected with a foot instep connecting strap 5, which is located at the corresponding position of the opening 13 and is located in front of the ankle connecting strap 4. The inner side of the foot instep connecting strap 5 is provided with a Velcro area. Preferably, in this embodiment, one end of the foot instep connecting strap 5 is integrally connected to the right side of the shoe panel 200 corresponding to the opening 13, and the other end of the foot instep connecting strap 5 is arranged at the opening 13 along the left and right direction of the shoe panel 200, thereby realizing the cross arrangement of the integral connection positions of the ankle connecting strap 4 and the foot instep connecting strap 5.

[0054] In this embodiment, the foot instep connecting strap 5 adopts the same structure as the foot instep connecting strap 5 in Embodiment 1, and the connection between the two is the same as the connection structure described in Embodiment 1, that is, the two are connected together by a second Velcro, and the Velcro area here is the area for the second Velcro to be set.

[0055] Preferably, the foot instep connecting strap 5 has a hollowed-out portion 53 to make the foot instep connecting strap 5 thinner and more breathable. The hollowed-out portion 53 can be set as a circle, strip, or other irregular shape as needed, so as to further reduce the overall weight and improve the breathability when wearing while ensuring the structural strength of the foot instep connecting strap 5.

[0056] This embodiment presents an integrated shoe panel. Compared with existing technologies, by designing the shoe panel 200 as an integrated structure and extending the heel connecting strap 3, ankle connecting strap 4, and instep connecting strap 5 in one piece, the overall weaving and forming of the outer shoe upper layer 1 is achieved, avoiding the complex structure of traditional shoe panels with multiple pieces spliced ​​together. Furthermore, this integrated shoe panel design allows for the completion of the weaving of the shoe panel 200 and each connecting strap in one go when using a large circular knitting machine, greatly reducing subsequent cutting and sewing processes. This not only improves production efficiency but also reduces the risk of errors caused by splicing, while avoiding problems caused by reverse interface structures. Moreover, the rearward-extending opening on the shoe panel 200 naturally forms the shoe opening 12 and the open opening 13 after the connecting straps are engaged, eliminating the need for additional three-dimensional cutting steps and simplifying the three-dimensional forming process of the shoe upper.

[0057] Example 3 The manufacturing process of a one-piece three-dimensional shoe upper, such as Figure 6 As shown, it includes the following steps: Step 1: Inner shoe upper layer knitting. The first yarn is knitted into an inner shoe upper layer 2 with an integrated sock-like structure using computerized knitting equipment (such as a sock knitting machine). This sock-like structure has a three-dimensional contour that fits the human foot, including parts corresponding to the ankle, instep and heel.

[0058] Furthermore, the structure of the inner shoe upper layer 2 is the same as that of the inner shoe upper layer 2 in Embodiment 1, and the first yarn uses conventional yarns, such as yarns formed by heating and melting monofilaments or monofilaments plus multifilaments.

[0059] It should be noted that during the weaving process of the inner shoe upper layer 2, the yarn density can be adjusted in specific areas as needed to enhance local elasticity and support.

[0060] Step 2: Outer shoe upper layer weaving. Using a conventional weaving machine in conjunction with the one-piece shoe plate 200 in Example 2, the second yarn is woven into an one-piece structure outer shoe upper layer 1. During the weaving process, the outer shoe upper layer 1 is integrally formed with the heel connecting strap 3, the ankle connecting strap 4, and the instep connecting strap 5. At the same time, the corresponding shoe opening 12 and open opening 13 are formed at the opening of the shoe plate 200.

[0061] Furthermore, the second yarn mentioned above can be made of existing conventional yarns or functional yarns, such as wear-resistant yarns, breathable yarns, etc., or it can be woven from monofilaments or multifilaments made of similar high-strength, tough, and lightweight materials such as ultra-fine twisted hemp and ultra-high molecular weight polyethylene.

[0062] Furthermore, the structure of the outer shoe upper layer 1 is the same as that of the outer shoe upper layer described in Example 1.

[0063] Step 3: Assemble the connecting parts. Fix the second Velcro 42 and the third Velcro 52 with hook and loop surfaces on the outer side of the inner shoe upper layer 2 by heat pressing or sewing. Fix the first Velcro 31 and 32 respectively in the Velcro area of ​​the heel connecting strap 3 of the outer shoe upper layer 1, fix the second Velcro 41 with a fleece surface in the Velcro area of ​​the ankle connecting strap 4, and fix the third Velcro 51 with a fleece surface in the Velcro area of ​​the instep connecting strap 5.

[0064] It should be noted that since each Velcro strap can also be woven together during the weaving process of the outer shoe upper layer 1 or the inner shoe upper layer 2, step 3 can be deleted in this embodiment depending on the setting of the Velcro strap.

[0065] Step 4: Composite inner and outer shoe upper layers. The inner shoe upper layer 2 obtained in step S1 and the outer shoe upper layer 1 obtained in step S2 are composited together by high temperature hot pressing or bonding, so that the outer shoe upper layer 1 is tightly attached to the outer side of the inner shoe upper layer 2. During the composite process, it is necessary to ensure that the position of each connecting strip (3, 4, 5) corresponds to the position of the Velcro on the inner shoe upper layer 2 to avoid misalignment.

[0066] Specifically, the process of bonding the outer shoe upper layer 1 and the inner shoe upper layer 2 together is as follows: First, the inner shoe upper layer 2 is placed on the shoe last 6 and flattened; then, the outer shoe upper layer 1 is placed on the shoe last 6, and the outer shoe upper layer 1 is attached to the outer side of the inner shoe upper layer 1, and the two back connecting straps 3 cooperate with each other to form the back part, which is located at the back of the shoe last 6. At this time, the outer shoe upper layer 1 forms a three-dimensional structure.

[0067] Furthermore, the outer shoe upper layer 1 and the inner shoe upper layer 2 are hot-pressed together using a conventional high-temperature integrated three-dimensional seamless press (i.e., a 3D hot pressing machine or a three-dimensional pressing machine).

[0068] Furthermore, a step 5 can be added after step 4, as described below.

[0069] Step 5: Finished product inspection. The composite one-piece three-dimensional shoe upper is subjected to size measurement, connection strength test (such as Velcro adhesion force, magnetic attraction force) and appearance inspection. After ensuring that there are no defects, it is packaged and put into storage.

[0070] Through the above manufacturing process, efficient mass production of one-piece and seamless three-dimensional shoe uppers can be achieved. The integrated composite design of the outer shoe upper layer 1 and the inner shoe upper layer 2 reduces the traditional multi-piece splicing process, lowers labor costs and production cycle. In addition, the integrated weaving of each connecting strap ensures structural stability. The overall process is reasonable and suitable for industrial production needs.
