Description

Technical Field

[0001] This application relates to the field of footwear technology, and more particularly to a shock-absorbing and supportive insole with a height-increasing inner core. Background Technology

[0002] Traditional footwear midsoles are typically made from a single material through a one-piece molding process. While this structure is simple and inexpensive, the uniform material properties make it unable to meet the cushioning and support needs of different areas of the foot. Furthermore, shoes designed to increase height often simply use built-in height-increasing insoles. This not only exacerbates instability issues caused by insufficient support, increasing the risk of ankle sprains, but also fails to guarantee cushioning performance and wearing comfort when height is increased.

[0003] Therefore, how to provide a midsole that adapts to the needs of different areas of the human foot is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] This application provides a shock-absorbing, supportive inner height-increasing sole that adapts to different needs of the human foot and improves wearing comfort.

[0005] The technical solution adopted in this application is: A shock-absorbing, high-heeled insole includes: The shock-absorbing support layer has a heel area, an arch area and a forefoot area corresponding to the human foot. The vertical thickness of the shock-absorbing support layer in the heel area is set within a preset range, and the heel area transitions smoothly to the forefoot area. Multiple functional components disposed on the top surface of the shock-absorbing support layer include: A first shock absorber is provided in the heel region; A second shock absorber is located in the forefoot region; And a support member located in the arch area; The rigidity of the support member is greater than that of the first damping member and the second damping member.

[0006] Preferably, the support is made of nylon or carbon fiber.

[0007] Preferably, both the first and second shock absorbers are made of one or more of E-TPU, PU, ​​sponge, and latex materials.

[0008] Preferably, the inner height-increasing sole of the shock-absorbing support further includes a first fabric layer and a second fabric layer respectively attached to the top and bottom surfaces of the shock-absorbing support layer.

[0009] Preferably, both the first fabric layer and the second fabric layer are made using a double-needle process.

[0010] Preferably, the shock-absorbing support inner height-increasing sole further includes a breathable layer disposed on the top surface of the first fabric layer.

[0011] Preferably, the breathable layer is made of sponge material.

[0012] Preferably, the shock-absorbing support inner height-increasing sole further includes a printed layer disposed on the top surface of the breathable layer.

[0013] Preferably, the printed layer has a positioning opening that matches the shape of the functional component, and the positioning opening is used to accommodate the functional component.

[0014] Preferably, the shock-absorbing support layer is made of EVA material.

[0015] According to the specific embodiments provided in this application, the following technical effects are disclosed: This application provides a shock-absorbing support midsole, comprising: a shock-absorbing support layer having a heel area, an arch area, and a forefoot area corresponding to the human foot; the vertical thickness of the shock-absorbing support layer in the heel area is set within a preset range, and the heel area transitions smoothly to the forefoot area; and multiple functional components disposed on the top surface of the shock-absorbing support layer, including: a first shock-absorbing component disposed in the heel area; a second shock-absorbing component disposed in the forefoot area; and a support component disposed in the arch area; wherein the rigidity of the support component is greater than that of the first and second shock-absorbing components. By setting different functional components on the shock-absorbing support layer corresponding to the foot areas, the solution allows different areas of the midsole to perform their respective functions. The first and second shock-absorbing components in the heel and forefoot absorb impact and provide rebound, while the support component in the arch provides torsional rigidity and support. The three functional components work together to improve the performance and wearing comfort of the midsole. Simultaneously, the shock-absorbing support layer has a certain thickness, achieving the physical height-increasing function of the midsole. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] As described in the background section, traditional footwear midsoles are typically made from a single material through a one-piece molding process. While this structure is simple and inexpensive, the uniformity of the material properties makes it unable to meet the cushioning and support needs of different areas of the human foot.

[0021] Based on this, this application provides a shock-absorbing and supportive midsole for height increase, aiming to solve the technical problem in the prior art where the midsole cannot adapt to the needs of different areas of the human foot and the need for height increase.

[0022] The embodiments of this application will be analyzed in detail below with reference to the accompanying drawings.

[0023] refer to Figure 1 and Figure 2 A shock-absorbing support insole includes: a shock-absorbing support layer 1 having a heel region, an arch region, and a forefoot region corresponding to the human foot; a plurality of functional components 2 disposed on the top surface of the shock-absorbing support layer 1, including: a first shock-absorbing component 20 disposed in the heel region; a second shock-absorbing component 21 disposed in the forefoot region; and a support component 22 disposed in the arch region; wherein the rigidity of the support component 22 is greater than the rigidity of the first shock-absorbing component 20 and the second shock-absorbing component 21.

[0024] In a preferred embodiment, the shock-absorbing support layer 1 is made of EVA material.

[0025] The cushioning support layer 1 serves as the base structure. The use of EVA material gives it good flexibility and support strength, providing necessary cushioning and support for the foot without excessively increasing the weight and hardness of the midsole. The first cushioning component 20, the support component 22, and the second cushioning component 21 are arranged sequentially along the length of the cushioning support layer 1, providing strong support to the arch area to stabilize gait and prevent excessive torsion. This allows the heel and forefoot areas to absorb impact and provide rebound. The three components work together to balance cushioning and support functions, improving the performance and comfort of the midsole.

[0026] As a preferred embodiment, the vertical thickness of the cushioning support layer 1 in the heel area is set within a preset range, and the heel area presents a smooth slope transition to the forefoot area, thereby realizing the physical height increase function of the midsole.

[0027] The preset range can be set to 3 to 10 cm.

[0028] As a preferred embodiment, the support member 22 is made of nylon or carbon fiber.

[0029] Nylon material boasts high hardness, strong support, and good toughness. Its use ensures the integrity of the support component 22's shape and function under long-term, repeated stress, preventing performance failure due to wall fracture. Carbon fiber material possesses extremely high specific stiffness and specific strength, providing strong bending and torsional rigidity while achieving lightweight design. This provides stable support for the arch area, effectively preventing arch collapse. Furthermore, carbon fiber's fatigue resistance ensures that the support component 22's performance does not degrade under long-term, high-intensity use.

[0030] In a preferred embodiment, both the first damping member 20 and the second damping member 21 are made of any one or more of E-TPU material, PU material, sponge material and latex material.

[0031] The first and second cushioning components 20 and 21 utilize the lightweight, high resilience, and energy return properties of E-TPU material to compress and absorb energy upon impact, then immediately return to their original shape. PU material provides a more durable cushioning feel compared to E-TPU, exhibiting excellent resistance to compression deformation and superior durability. Sponge material is lightweight, inexpensive, and easy to mold, providing initial cushioning. Latex material has excellent shock absorption properties, effectively dispersing impact pressure and enhancing wearing comfort.

[0032] As an example, when the first damping element 20 and the second damping element 21 are made of multiple materials, their composite structure includes, but is not limited to: physical blend structure, multi-layer composite structure, particle-filled structure, or partitioned combination structure. This composite approach can integrate the performance advantages of each individual material, achieving synergy in performance parameters such as damping, rebound, tactile feel, and durability to meet the needs of different application scenarios.

[0033] As a preferred embodiment, refer to Figure 1 The shock-absorbing support inner height-increasing sole also includes a first fabric layer 3 and a second fabric layer 4 respectively attached to the top and bottom surfaces of the shock-absorbing support layer 1.

[0034] The first fabric layer 3 provides a flat and easy-to-bond base for the upper structure of the midsole. The second fabric layer 4 can serve as a bonding layer with the outsole and also wraps around the cushioning support layer 1, improving the overall integrity and unity of the midsole structure and preventing interlayer delamination.

[0035] In a preferred embodiment, both the first fabric layer 3 and the second fabric layer 4 are made using a double-needle process.

[0036] The fabric made using a double-needle process has higher density and tear resistance, and when used as a midsole, it can enhance the durability of the midsole.

[0037] As a preferred embodiment, refer to Figure 1 The shock-absorbing support inner height-increasing sole also includes a breathable layer 5 located on the top surface of the first fabric layer 3.

[0038] Among them, the breathable layer 5 can improve the overall breathability and moisture-wicking performance of the midsole, preventing sweat from accumulating in the shoe cavity, thereby improving the dryness and comfort of wearing.

[0039] In a preferred embodiment, the breathable layer 5 is made of sponge material.

[0040] The sponge material has a porous structure, which provides excellent breathability and moisture absorption.

[0041] As a preferred embodiment, refer to Figure 1 and Figure 2 The shock-absorbing support inner height-increasing sole also includes a printed layer 6 located on top of the breathable layer 5.

[0042] Among them, the printed layer 6 can not only carry the brand logo and decorative patterns to enhance the product's aesthetics, but also serve as the surface layer that comes into direct contact with the soles of the feet, and its material itself can provide a comfortable feel.

[0043] As a preferred embodiment, refer to Figure 1 and Figure 2 The printed layer 6 has a positioning opening 60 that matches the shape of the functional component 2. The positioning opening 60 is used to accommodate the functional component 2.

[0044] The positioning port 60 can limit the first cushioning component 20, the second cushioning component 21 and the support component 22, preventing them from shifting or deflecting due to repeated stress during the use of the shoe, thus ensuring the reliability and durability of the product.
