Description

Technical Field

[0001] This utility model relates to the field of shoe sole technology, and in particular to a high-elasticity composite shoe sole. Background Technology

[0002] In modern footwear design, the elasticity of the sole is one of the important indicators for evaluating its comfort and functionality. An ideal athletic shoe sole should possess high elasticity to ensure effective shock absorption and sufficient energy return during exercise. However, while traditional sole materials such as EVA (ethylene-vinyl acetate copolymer) and rubber possess a certain degree of elasticity and abrasion resistance, these materials exhibit relatively small deformation upon impact, resulting in poor sole elasticity. Utility Model Content

[0003] To address the problem that traditional shoe soles exhibit limited deformation when subjected to external impact, resulting in poor elasticity, this invention provides a highly elastic composite shoe sole.

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] An embodiment of this utility model provides a highly elastic composite shoe sole, comprising, from top to bottom:

[0006] The upper sole is made of PEBA.

[0007] The first midsole is made of carbon fiber.

[0008] The second midsole is made of PEBA and has a first deformation groove located in the connection area between the forefoot and the outer side.

[0009] Outsole, the outsole material is rubber.

[0010] According to some embodiments of the present invention, the second midsole is further provided with a second deformation groove located in the heel area.

[0011] According to some embodiments of the present invention, the second midsole is further provided with a groove located at the upper end of the forefoot region.

[0012] According to some embodiments of the present invention, the first deformation groove extends from the outer side of the second midsole to the inner side of the second midsole, and the first deformation groove extends obliquely from the outer region to the forefoot region.

[0013] According to some embodiments of the present invention, the second middle bottom is provided with a mounting groove for mounting the outer bottom.

[0014] According to some embodiments of the present invention, the outer base includes a rubber sheet that mates with the mounting groove.

[0015] According to some embodiments of the present invention, the rubber sheet is a plurality of sheets, and the plurality of rubber sheets are respectively installed in the mounting groove.

[0016] According to some embodiments of the present invention, the rubber sheet is provided with anti-slip protrusions.

[0017] This invention offers at least the following advantages: The use of PEBA material provides excellent elasticity to the sole, effectively absorbing impact. The use of carbon fiber helps reduce the weight of the sole, improving wearing comfort. Because the first deformation groove is located at the connection between the forefoot and lateral regions, when the sole receives a large impact, the materials in the forefoot and lateral regions can deform towards the first deformation groove. This groove provides space for the deformation of the materials in the forefoot and lateral regions, allowing for greater deformation and increasing the sole's elasticity, enabling it to better adapt to different sports demands. The rubber outsole ensures the durability and slip resistance of the sole in various environments. This composite sole design combines the advantages of multiple materials, providing a lightweight sole with high elasticity and wear resistance. Attached Figure Description

[0024] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0025] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0027] An embodiment of this utility model provides a highly elastic composite shoe sole, such as... Figure 1-6 As shown, from top to bottom, they include:

[0028] The upper outsole is 100, and the material of the upper outsole is PEBA.

[0029] The first midsole 200 is made of carbon fiber.

[0030] The second midsole 300 is made of PEBA and has a first deformation groove 310 located in the connection area between the forefoot region 10 and the outer region 13.

[0031] Outsole 400, the outsole material is rubber.

[0032] The upper 100 is made of PEBA (polyether block amide). Connected to the upper, PEBA offers high elasticity and durability, enhancing its responsiveness. The first midsole 200 is made of carbon fiber, a high-strength and lightweight material that provides additional support and stability. The second midsole 300 is also made of PEBA to ensure overall sole elasticity and comfort.

[0033] like Figure 1As shown, the sole is divided into four areas according to the corresponding positions of the foot: the forefoot area 10, the arch area 11, the heel area 12, and the lateral area 13. The second midsole 300 has a first deformation groove 310 located at the connection area between the forefoot area 10 and the lateral area 13. Because the first deformation groove is located at the connection area between the forefoot area and the lateral area, when the sole receives a large impact, the material of the forefoot area and the lateral area can deform towards the first deformation groove. The first deformation groove provides space for the deformation of the material in the forefoot area and the lateral area, allowing for greater deformation and increasing the elasticity of the sole. This design helps to provide better elasticity and flexibility during walking or sports. The outsole 400 is made of rubber, which provides good abrasion resistance and grip, ensuring the stability and durability of the sole on various surfaces. Through the use of PEBA material, the sole has excellent elasticity and can effectively absorb impact. The use of carbon fiber helps reduce the weight of the sole and improve wearing comfort. The first deformation groove 310 design of the second midsole 300 increases the elasticity of the sole, allowing it to better adapt to different sports needs. The rubber outsole 400 ensures the durability and slip resistance of the sole in various environments. This composite sole design combines the advantages of multiple materials to provide a lightweight yet highly elastic and durable sole.

[0034] In some embodiments, the second midsole 300 is further provided with a second deformation groove 320 located in the heel region 12.

[0035] The design of the second deformation groove 320 increases the flexibility and adaptability of the heel area 12, helping to better absorb impact during walking or exercise and providing a more natural foot movement. By adding the second deformation groove 320 to the heel area 12, the overall flexibility of the sole is improved, allowing it to better adapt to the natural movement of the foot. The second deformation groove 320 helps to disperse and absorb impact from the ground, reducing pressure on the foot and leg. By enhancing the flexibility and impact absorption capacity of the sole, wearing comfort is improved. This embodiment further optimizes the sole design, providing additional flexibility and impact absorption capacity not only in the connection area between the forefoot area 10 and the lateral area 13, but also in the heel area 12. This design is particularly suitable for occasions requiring high-intensity exercise and prolonged standing.

[0036] Furthermore, the second midsole 300 also has a groove 330 located at the upper end of the forefoot region 10.

[0037] The groove 330 is designed to provide additional flexibility and adaptability, particularly in the forefoot region 10, a key stress area for the foot during walking and movement. The groove 330 allows for greater deformation space in the forefoot region 10 under stress, thus improving the flexibility and adaptability of the sole. By placing the groove 330 at the upper end of the forefoot region 10, pressure on the foot is better distributed, reducing excessive localized stress. This improved design helps provide a more natural foot movement, reducing fatigue and thus enhancing wearing comfort.

[0038] By combining the groove 330 at the upper end of the forefoot area 10, the second deformation groove 320 of the heel area 12, and the first deformation groove 310 in the connection area between the forefoot area 10 and the lateral area 13, this composite sole design provides optimized support and flexibility in multiple key areas. This design is particularly suitable for athletic shoes that require high flexibility and shock absorption, and is also suitable for occasions requiring prolonged standing or walking.

[0039] In some embodiments, the first deformation groove 310 extends from the outer side of the second midsole 300 to the inner side of the second midsole 300, and the first deformation groove 310 extends obliquely from the outer region 13 to the forefoot region 10.

[0040] The first deformation groove 310 starts from the outer side of the second midsole 300 and extends inward, and the first deformation groove 310 extends obliquely from the outer area 13 to the forefoot area 10. This oblique design can better adapt to the natural movement trajectory of the foot.

[0041] In some embodiments, the second insole 300 is provided with a mounting groove 340 for mounting the outsole 400.

[0042] Mounting slot 340 is used to mount the outsole. This design ensures a more stable and secure connection between the outsole 400 and the second midsole 300. The mounting slot 340 allows the outsole 400 to be accurately placed in the predetermined position of the second midsole 300. This not only helps improve the overall structural stability of the sole but also ensures the uniformity and effectiveness of the outsole 400's abrasion layer when in contact with the ground.

[0043] Furthermore, the outsole 400 includes a rubber sheet 410 that mates with the mounting groove 340.

[0044] The outsole 400 includes a rubber sheet 410 for mating with a mounting groove 340 of the second midsole 300. This design ensures a tighter connection between the outsole 400 and the second midsole 300. The design of the rubber sheet 410 allows the outsole 400 to be accurately embedded in the mounting groove 340. This not only helps improve the overall structural stability of the sole but also ensures the uniformity and effectiveness of the abrasion layer of the outsole 400 in contact with the ground.

[0045] Furthermore, the rubber sheet 410 consists of multiple sheets, each of which is installed in the mounting groove 340.

[0046] The outsole 400 consists of multiple rubber sheets 410, each designed to mate with a mounting groove 340 of the second midsole 300. This segmented design provides specific functions such as abrasion resistance, slip resistance, or cushioning to meet the needs of different areas. The multiple rubber sheets are individually secured in the mounting grooves 340, ensuring that each rubber sheet 410 is firmly embedded in its corresponding groove. This not only enhances the connection stability between the outsole 400 and the second midsole 300 but also allows for optimized design for different areas.

[0047] Furthermore, anti-slip protrusions 420 are distributed on the rubber sheet 410.

[0048] The rubber sheet 410 has anti-slip protrusions 420 spaced apart. These protrusions can be of different shapes and sizes, such as circular, oval, strip-shaped, or other geometric shapes. The main function of the anti-slip protrusions 420 is to increase the friction between the sole and the ground, thereby improving anti-slip performance. These protrusions can embed into the tiny bumps and depressions in the ground upon contact, providing additional grip. By designing the anti-slip protrusions 420 on the rubber sheet 410, the sole not only performs excellently on dry surfaces but also maintains good grip on wet, slippery, or uneven surfaces. This design helps improve the wearer's walking stability and reduces the risk of slipping, especially during sports or outdoor activities. The anti-slip protrusions 420 also enhance the abrasion resistance of the sole because they distribute pressure upon contact with the ground.
