Description

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] Athletic shoes are a type of footwear specifically designed for various sports activities. They protect the feet, provide comfort, and enhance athletic performance, offering support and protection for the user.

[0003] Existing shoe soles are typically one-piece or multi-layered structures. For example, the utility model patent with application number CN201320333411.3, entitled "An Improved Shoe Sole," describes a sole comprising, from top to bottom, an upper sole plate, a midsole plate, and a lower sole plate. The upper sole plate is a MD upper sole plate, the lower sole plate is a hard MD lower sole plate, and the midsole plate is a soft MD midsole plate. The upper sole plate is a soft MD sole plate with a Shore hardness of 60 HA, the midsole plate is a soft MD sole plate with a Shore hardness of 40 HA, and the lower sole plate is a hard MD sole plate with a Shore hardness of 70 HA. The upper, mid, and lower sole plates are bonded together sequentially. Although the hardness of each layer of the sole differs from top to bottom, the hardness of the areas corresponding to the forefoot, arch, and heel of the foot remains consistent.

[0004] However, during exercise, the first step of starting and sudden stopping tends to generate force from the forefoot, while the heel is used more for adjustment upon landing. Therefore, shoe soles with the same hardness in the forefoot and heel are difficult to adapt to the different needs of users, which in turn affects the user's athletic performance. Utility Model Content

[0005] The purpose of this invention is to provide a sole and athletic shoe that improves the problem that existing athletic shoe soles do not have different hardness zones based on the force exertion characteristics during exercise, resulting in poor athletic performance.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A shoe sole, comprising:

[0008] The shoe midsole includes a forefoot midsole and a rear midsole that is joined and assembled with the forefoot midsole, wherein the hardness of the forefoot midsole is less than that of the rear midsole;

[0009] The outsole, which is disposed on the bottom surface of the midsole; and

[0010] A support member is disposed between the midsole and the outsole of the shoe, wherein the hardness of the support member in the forefoot area is less than that in the heel area.

[0011] Preferably, the bottom of the rear midsole has a notch with a triangular longitudinal section at the arch position, and the support member has a protrusion that matches the notch.

[0012] Preferably, the support member includes a first support plate and a second support plate, the first support plate being disposed between the forefoot midsole and the outsole, and the second support plate being disposed between the rearfoot midsole and the outsole; the hardness of the first support plate is lower than that of the second support plate;

[0013] The first support plate has a first overlapping portion at the arch position, and the second support plate has a second overlapping portion that overlaps and cooperates with the first overlapping portion; the first overlapping portion and the second overlapping portion overlap each other to form the protrusion that matches the notch.

[0014] Preferably, the first support plate has two support portions in the forefoot area that extend along the front end of the sole and to both sides.

[0015] Preferably, the second support plate has a retaining portion surrounding the rear midsole at the heel position.

[0016] Preferably, the support member has a baffle at the inner arch position, and the shoe midsole has a groove at the position of the baffle that matches it.

[0017] Preferably, the outsole is made of rubber and has anti-slip texture on its bottom surface.

[0018] Preferably, the support member has a plurality of positioning protrusions on the side facing the outsole; the outsole has positioning through holes or positioning grooves that engage with the positioning protrusions.

[0019] Preferably, a plurality of the positioning protrusions form a first limiting portion in the forefoot area of ​​the support member, a second limiting portion in the heel area of ​​the support member, and a third limiting portion in the arch area of ​​the support member.

[0020] A sports shoe is also provided, including the aforementioned sole.

[0021] By adopting the above technical solution, this utility model has the following advantages compared with the prior art:

[0022] 1. The hardness of the forefoot midsole of this utility model is lower than that of the rear midsole, which will buffer the impact force during exercise and have the effect of accelerating the start; at the same time, the forefoot is wrapped with the first support plate and the rearfoot is wrapped with the second support plate, so that the foot can be stabilized during vigorous exercise, thus preventing falls and sprains.

[0023] 2. The midsole of this utility model is designed to be disassembled and joined, which makes it easy to produce forefoot and rearfoot midsoles with different hardness. The forefoot and rearfoot midsoles can be joined in the arch area. The rearfoot midsole extends towards the side of the forefoot on at least one side to form an open-type wrap-around structure, which makes the forefoot and midsole firmly joined and ensures the stability of the structure.

[0041] Example 1

[0042] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment provides a shoe sole, including a midsole 10, an outsole 11, and a support member 12. The midsole 10 includes a forefoot midsole 101 and a rear midsole 102 that is joined and assembled with the forefoot midsole 101. The hardness of the forefoot midsole 101 is less than that of the rear midsole 102. The outsole 11 is disposed on the bottom surface of the midsole 10. The support member 12 is disposed between the midsole 10 and the outsole 11. The hardness of the support member 12 in the forefoot area is less than that in the rearfoot area. The support member 12 can be made of TPU material. The outsole 11 is made of rubber and its bottom surface is provided with anti-slip patterns 111, such as a grid-like, strip-shaped, or block-shaped anti-slip pattern 111 structure, to ensure the friction performance of the shoe sole.

[0043] Specifically, the hardness of the forefoot and heel of the midsole 10 is differentiated. For example, the forefoot midsole 101 is made of a soft, foamy material, while the heel midsole 102 is made of a harder molded plastic material (also known as MD material, which is lightweight, slip-resistant, and wear-resistant. The main components of MD material include EVA and rubber. After special mixing and processing, these two materials form an MD sole material with a midsole foam structure. MD material also has good wear resistance, which can effectively reduce the wear of the sole and extend the life of the shoe). This makes the heel of the midsole 10 relatively harder to improve the support of the heel area, while ensuring the elasticity of the forefoot area, thus cushioning the impact during exercise. Similarly, to ensure this performance, the hardness of the forefoot part of the support component 12 needs to be designed to be relatively low to ensure the elasticity of the forefoot. At the same time, the support component 12 can cover and support the foot, avoiding or reducing the risk of ankle sprains, thereby improving or guaranteeing the performance of the sole.

[0044] Furthermore, the forefoot midsole 101 and the rearfoot midsole 102 can be joined in the arch area, with the rearfoot midsole 102 extending towards the side of the forefoot on at least one side to form an open, wrap-around structure, which ensures that the forefoot midsole 101 is securely joined and guarantees the stability of the structure.

[0045] like Figure 3 As shown, in this embodiment, the bottom of the rear midsole 102 is provided with a notch 103 with a triangular longitudinal section at the arch position. The support member 12 is provided with a protrusion that matches the notch 103, that is, the longitudinal section of the protrusion is also a triangle that matches the notch 103. In this way, the stability of the triangle is used to support the arch area of ​​the shoe midsole 10, which has good structural stability.

[0046] In this embodiment, the support member 12 includes a first support plate 121 and a second support plate 122. The first support plate 121 is disposed between the forefoot midsole 101 and the outsole 11, and the second support plate 122 is disposed between the rearfoot midsole 102 and the outsole 11. The hardness of the first support plate 121 is lower than that of the second support plate 122. The first support plate 121 is provided with a first overlapping portion 1212 at the arch position, and the second support plate 122 is provided with a second overlapping portion 1221 that overlaps and cooperates with the first overlapping portion 1212. The first overlapping portion 1212 and the second overlapping portion 1221 overlap each other to form a protrusion that matches the notch 103.

[0047] Specifically, the design of the support plates through disassembly and docking facilitates the production of support plates with different hardnesses. Simultaneously, the overlapping design creates an overlapping connection. For example, the first overlapping portion 1212 is clamped between the shoe midsole 10 and the second overlapping portion 1221, and is limited by a protruding structure (i.e., the first overlapping portion 1212 and the second overlapping portion 1221 overlap to form a protrusion that matches the notch 103), ensuring that the first support plate 121 and the second support plate 122 do not separate. Simultaneously, the overlapping portion also provides a positioning and installation effect.

[0048] Furthermore, the separate first support plate 121 and second support plate 122 facilitate the differentiated design of hardness, so that the hardness of the first support plate 121 is lower than that of the second support plate 122, in order to match the hardness design of the shoe midsole 10, further improving the support of the rearfoot area and ensuring the elasticity of the forefoot area for flexion.

[0049] In this embodiment, the first support plate 121 has two support portions 1211 extending along the front end and both sides of the sole in the forefoot area. The support portions 1211 are relatively soft so as to wrap around and fit the forefoot. Specifically, there are two support portions 1211: one extends from the bottom surface of the forefoot to the outer side near the toe, and the other extends from the bottom surface of the forefoot to the inner side near the toe, forming a wrapping support with a good anti-spine sprain effect.

[0050] In this embodiment, the second support plate 122 is provided with a baffle 1222 surrounding the rear midsole 102 at the heel position, so as to cover and support the side of the rear foot and the side of the heel of the shoe midsole 10, forming a support effect to ensure the support strength of the rear foot area.

[0051] like Figure 1 As shown, in this embodiment, the support member 12 is provided with a baffle 12211 at the inner arch position, and the midsole 10 is provided with a groove (not shown in the figure) that matches the baffle 12211 at the position of the baffle 12211. By the overlap and cooperation between the baffle 12211 and the groove on the side of the midsole 10, the support strength of the side of the midsole can be improved.

[0052] In this embodiment, the support member 12 has several positioning protrusions 123 on the side facing the outsole 11; the outsole 11 has positioning through holes 112 or positioning grooves that engage with the positioning protrusions 123. Through the cooperation of the positioning protrusions 123 and the positioning through holes 112, the positioning support plate can be engaged, thereby improving the stability of the structure. Simultaneously, the interior of the outsole can be observed to understand the material design, allowing consumers to have a more accurate understanding of the shoe.

[0053] Furthermore, in this embodiment, a plurality of positioning protrusions 123 form a first limiting portion (not shown in the figure) in the forefoot area of ​​the support member 12, a second limiting portion (not shown in the figure) in the heel area of ​​the support member 12, and a third limiting portion (not shown in the figure) in the arch area of ​​the support member 12.

[0054] Specifically, the first limiting part is set on the two support parts 1211, forming two protruding points. Corresponding positioning through holes 112 are opened on the outsole 11, so that the two points correspond to the two ends of the positioning through holes 112. The area between the two points can be filled by the midsole 10, forming a protruding structure that engages with the positioning through holes 112. Similarly, the second and third limiting parts can also be designed accordingly. If the area between the two points is a support plate, a protrusion is designed on the edge of the support plate to overlap and limit the positioning through holes 112; alternatively, it can be a design where one end is a support plate structure and the other end is a midsole structure. This ensures the purpose of the limiting design for the support plate is achieved.

[0055] Example 2

[0056] This utility model also provides a sports shoe, which includes the aforementioned sole. The forefoot of the sole is designed to be relatively soft to allow for bending and bouncing, while the heel is harder to provide sufficient support. The purpose of this design is to create different areas of hardness to adapt to the force exertion characteristics of people during exercise and to provide good assistance.

[0057] 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.
