Technical Field

[0001] This utility model relates to the field of footwear technology, specifically to a shoe sole and a sports shoe. Background Technology

[0002] The design of the sole structure of footwear products is particularly critical, as it directly affects the comfort, functionality, and durability of the footwear.

[0003] Most shoe soles on the market rely on the functionality of the materials themselves, lacking an active rebound and cushioning structure design. At the same time, they do not provide differentiated functional designs for different areas of the foot (forefoot, arch, heel), resulting in problems such as low rebound efficiency and insufficient cushioning. This leads to fatigue during long walks or sports, affecting wearing comfort and athletic performance. Utility Model Content

[0004] The purpose of this invention is to provide a sole and athletic shoe that improves the poor rebound and cushioning performance of existing athletic shoes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A shoe sole, comprising:

[0007] The shoe midsole includes an upper midsole and a lower midsole stacked together. The lower midsole has a shock-absorbing groove extending through the width of the lower midsole at the arch position. The lower midsole has a through hole for viewing the interior of the shoe midsole. The through hole and the shock-absorbing groove are at least partially connected.

[0008] The upper midsole has an elastic support portion at the heel position, and the lower midsole has a protrusion at the heel position that fits into the support portion.

[0009] A support member, disposed between the upper middle sole and the lower middle sole; and

[0010] The outsole is located on the bottom surface of the midsole.

[0011] Preferably, the protrusion is provided with a first contour groove for fitting and placing the rear foot portion of the support member.

[0012] Preferably, an adjustment block for providing elasticity is provided at the forefoot position of the upper midsole, and the adjustment block is separately or integrally formed with the upper midsole;

[0013] The elastic modulus of the adjusting block is lower than that of the upper midsole and / or the lower midsole.

[0014] Preferably, the adjusting block and the upper midsole are separately disposed, and the forefoot portion of the support member is disposed between the adjusting block and the upper midsole;

[0015] Alternatively, the adjustment block is integrally formed with the upper midsole, and the forefoot portion of the support member is located between the lower midsole and the upper midsole.

[0016] Preferably, the adjustment block is separately disposed from the upper midsole, and a second contour groove for fitting and placing the adjustment block is provided at the forefoot position of the lower midsole;

[0017] The second contour groove and the shock-absorbing groove share a sidewall, and the sidewall is a limiting part for limiting the adjustment block.

[0018] Preferably, the forefoot position of the shoe midsole has a warped structure facing the toe.

[0040] Example 1

[0041] Please refer to Figure 1 and Figure 3As shown, this embodiment provides a shoe sole, including a midsole 10, a support member 11, and an outsole 12. The midsole 10 includes an upper midsole 101 and a lower midsole 102 stacked together. The lower midsole 102 has a cushioning groove 1021 extending through the lower midsole 102 in the width direction at the arch position. The lower midsole 102 has a through hole 1022 for viewing the interior of the midsole 10. The through hole 1022 and the cushioning groove 1021 are at least partially connected. The upper midsole 101 has an elastic support portion 1011 at the heel position. The lower midsole 102 has a protrusion 1023 at the heel position that engages with the support portion 1011. The support member 11 is disposed between the upper midsole 101 and the lower midsole 102. The outsole 12 is disposed on the bottom surface of the midsole 10.

[0042] Specifically, the lower midsole 102 and the upper midsole 101 are fixedly connected by adhesive or hot pressing. The materials of the upper midsole 101 and the lower midsole 102 can be EVA (ethylene-vinyl acetate copolymer) or TPU (thermoplastic polyurethane elastomer rubber), which have good shock absorption and resilience. The shock-absorbing groove 1021 forms a through groove structure that runs through both sides of the shoe midsole 10, which increases the elastic deformation space of the sole. When the user walks or exercises, the shock-absorbing groove 1021 can deform with the pressure of the foot and restore its deformation when the foot is lifted, thereby effectively absorbing the impact force and improving the rebound efficiency. Meanwhile, the design of the through hole 1022 not only facilitates the observation of the support component 11 set inside the midsole 10, but also enhances the overall cushioning effect in conjunction with the cushioning groove 1021. Since the cushioning groove 1021 is partially connected to the through hole 1022, when the cushioning groove 1021 is deformed under pressure, the through hole 1022 can expand slightly to improve the rebound cushioning performance.

[0043] Furthermore, the support portion 1011 located at the heel of the upper midsole 101 increases the thickness of the heel area, thereby enhancing the support in this area and effectively cushioning the impact of heel strike. The corresponding protrusion 1023 on the lower midsole 102 engages with the support portion 1011, forming a stable structural fit that further enhances the stability and torsional rigidity of the heel area, as well as the tightness of the connection between the upper midsole 101 and the lower midsole 102. The support member 11 is made of a material with higher hardness than the upper midsole 101 and the lower midsole 102, such as a carbon fiber plate, to enhance the support and stability of the sole and effectively prevent excessive twisting or bending of the sole during vigorous exercise.

[0044] The outsole 12 is made of wear-resistant rubber material, and the bottom surface is provided with multiple anti-slip ridges (not shown in the picture) to enhance the friction between the sole and the ground and improve grip performance.

[0045] In this embodiment, the protrusion 1023 is provided with a first contour groove (not shown in the figure) for fitting and placing the support member 11 on the heel portion. The first contour groove positions and limits the support member 11, preventing displacement or shifting of the support member 11 during use, while ensuring accurate positioning of the support member 11 during assembly, thereby improving the overall stability of the shoe sole structure.

[0046] like Figure 3 As shown, in another embodiment, an adjustment block 1012 for providing elasticity is provided at the forefoot position of the upper midsole 101. The adjustment block 1012 is either separate from or integrally molded with the upper midsole 101. The adjustment block 1012 is made of an elastic material, and its elastic modulus is lower than that of the upper midsole 101 and the lower midsole 102. It can deform and recover quickly under external force. It can be made of modified EVA (by adjusting the VA content or reducing the hardness through foaming process) or foamed silicone. This effectively absorbs the impact energy when the forefoot lands and rebounds quickly during the push-off phase, making the sole more suitable for sports that require frequent push-off movements. It can better adapt to the dynamic changes of the foot, reduce fatigue after prolonged wear, and improve wearing comfort.

[0047] The adjustment block 1012 can be separately installed from the upper midsole 101 or integrally molded with it. Both methods achieve good elasticity and localized cushioning. When the adjustment block 1012 is separately installed from the upper midsole 101, the forefoot portion of the support member 11 is positioned between the adjustment block 1012 and the upper midsole 101. When the adjustment block 1012 is integrally molded with the upper midsole 101, the forefoot portion of the support member 11 is positioned between the lower midsole 102 and the upper midsole 101. The support member 11 provides rigid support to the sole, while the support portion 1011 provides support to the heel. Combined with the localized rebound and cushioning effect of the adjustment block 1012, differentiated performance control is achieved for different areas of the sole, resulting in synergistic optimization of high forefoot rebound and strong heel support.

[0048] When the adjustment block 1012 and the upper midsole 101 are set separately, a second contour groove (not shown in the figure) is provided at the forefoot position of the lower midsole 102 for fitting and placing the adjustment block 1012; the second contour groove and the shock-absorbing groove 1021 share a side wall, and the side wall is a limiting part 1024 for limiting the adjustment block 1012.

[0049] Specifically, the depth of the second contour groove matches the thickness of the adjusting block 1012, and the limiting part 1024 positions and limits the adjusting block 1012 to ensure that the adjusting block 1012 will not shift when subjected to force, thus ensuring its stability during movement.

[0050] like Figure 1 and Figure 3As shown, in this embodiment, a warping structure 103 is provided at the forefoot position of the midsole 10, facing the toe. The warping structure 103 can guide the foot to roll naturally during walking or running, improving propulsion efficiency.

[0051] Example 2

[0052] like Figure 2 and Figure 4 As shown, this embodiment provides a sports shoe, including a sole 1 and an upper 2. The upper 2 is disposed on the top surface of the sole 1. The sole 1 is the sole described in Embodiment 1. In one embodiment, the sole 1 does not have an adjustment block 1012. In this case, the sole 1 only achieves cushioning and rebound through the cushioning groove 1021, and works with the support part 1011 to improve the support and cushioning effect at the heel. In another embodiment, the sole 1 adds an adjustment block 1012 to further improve the cushioning and rebound performance of the forefoot. Through the above structural design, the sole 1 provides good support and cushioning and rebound performance, while also effectively adapting to the dynamic needs of sports scenarios, thus improving overall sports performance.

[0053] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
