Description

Technical Field

[0001] This utility model relates to a... Background Technology

[0002] The structural design of athletic shoe soles directly affects the wearing experience and athletic performance. In particular, the midsole, as the core cushioning and support component, has always been a key focus of the industry in terms of material selection and structural innovation. Traditional solutions have the following technical bottlenecks: a single material cannot simultaneously provide support and comfort. Early soles often used single-density materials (such as EVA or rubber). While high-hardness materials can provide stable support, their shock absorption is poor, easily leading to foot fatigue. Low-hardness materials (such as foamed EVA) improve comfort, but they are prone to collapse and deformation after long-term compression (deformation can reach 20%), and lack arch support, leading to an increased risk of plantar fasciitis. Utility Model Content

[0003] The purpose of this invention is to propose a sole structure that can effectively improve comfort and support.

[0004] To solve the above problems, this utility model provides a shoe sole with a double-layer midsole structure, characterized in that it includes: a midsole and an outsole, and is characterized in that:

[0005] The midsole includes an outer frame, a padding body, and an elastic support body. The upper surface of the outer frame has a recessed mounting groove at least at the arch. The support body is made of elastic material and is installed at the bottom of the mounting groove. The padding body is located above the support body and fills the mounting groove. The elasticity of the padding body is less than that of the outer frame, and the hardness of the outer frame is greater than that of the padding body.

[0006] The outsole is attached to the bottom of the outer frame, and the bottom of the outsole is provided with a plurality of anti-slip blocks.

[0007] As a further improvement of this utility model, the filling material is a porous polymer formed by supercritical foaming technology using aromatic TPU.

[0008] As a further improvement of this utility model, the outer frame is a porous polymer formed by supercritical foaming technology from aliphatic TPU.

[0009] As a further improvement of this utility model, the support body is a nylon plate.

[0010] As a further improvement of this utility model, the outer frame is provided with a hollow area, which is located at the bottom of the mounting groove and extends through the outer frame.

[0011] The beneficial effects of this utility model are that the midsole is provided with an outer frame and a filling body, which have different hardness and elasticity. The filling body is in contact with the foot, and its feel is softer and more elastic, providing a comfortable feel. The outer frame is harder and provides better strength. In addition, a support body with elasticity is provided in the midsole to provide support and propulsion for the foot. Attached Figure Description

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] Example 1

[0019] like Figure 1-5 As shown, this embodiment includes a midsole 200 and an outsole 400. The midsole 200 includes an outer frame 202, a padding body 204, and an elastic support body 206. The upper surface of the outer frame 202 has a recessed mounting groove 205 at least at the arch. The support body 206 is made of elastic material and is installed at the bottom of the mounting groove 205. The padding body 204 is located above the support body 206 and fills the mounting groove 205. The elasticity of the padding body 204 is less than that of the outer frame 202, and the hardness of the outer frame 202 is greater than that of the padding body 204. The outsole 400 is attached to the bottom of the outer frame 202, and a plurality of anti-slip blocks are provided on the bottom of the outsole 400. The padding body 204 is a porous polymer formed by supercritical foaming technology using aromatic TPU. The outer frame 202 is a porous polymer formed by supercritical foaming technology using aliphatic TPU. The support body 206 is a nylon sheet. In this embodiment, the midsole 200 is provided with an outer frame 202 and a padding body 204, which have different hardness and elasticity. The padding body 204 is in contact with the foot, and its feel is softer and more elastic, providing a comfortable feel. The outer frame 202 is harder and provides better strength. In addition, a support body 206 is provided in the midsole 200 and has elasticity, providing support and propulsion for the foot.

[0020] Example 2

[0021] In this embodiment, the outer frame 202 is provided with a hollow area 208, which is located at the bottom of the mounting groove 205 and extends through the outer frame 202. The purpose of providing the hollow area 208 in this embodiment is to effectively reduce the weight of the shoe body and improve its portability. In addition, the nylon board can be seen through the hollow area 208, which improves the visual appeal of the technology.

[0022] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
