Description

Technical Field

[0001] This utility model relates to the field of footwear rubber technology, and more specifically to a high-elasticity shock-absorbing footwear rubber. Background Technology

[0002] The construction of shoe soles is quite complex. Broadly speaking, it can include all materials that make up the bottom, such as the outsole, midsole, and heel. Narrowly defined, it refers only to the outsole. Common characteristics of shoe sole materials generally include abrasion resistance, water resistance, oil resistance, heat resistance, pressure resistance, impact resistance, good elasticity, easy adaptation to foot shape, resistance to deformation after shaping, heat retention, and easy moisture absorption. Simultaneously, it should work in conjunction with the midsole to provide braking during foot transitions to prevent slipping and facilitate stopping. Shoe soles include rubber, plastics, rubber-plastic composites, and recycled leather. However, current rubber soles, due to their relatively simple material structure, offer limited functionality and generally have poor elasticity. Conversely, rubber soles with good elasticity often have poor abrasion resistance, thus limiting their use. To address these issues, the inventor proposes a high-elasticity shock-absorbing rubber for shoes. By incorporating a silicone layer and an abrasion-resistant layer onto the rubber, the shock-absorbing and abrasion-resistant effects of the rubber are improved, making it more suitable for shoe sole construction and extending its service life.

[0003] To improve the elasticity of rubber shoe soles and increase wearing comfort, Chinese Patent (Authorization Announcement No.: CN221355961U) discloses a highly elastic and comfortable rubber shoe sole. This utility model includes: an upper pad, a lower pad, elastic pillars, and support pillars. The lower pad is located below the upper pad, and the bottom surface of the upper pad matches the top surface of the lower pad. The front and rear parts of the lower pad are respectively designated as the forefoot and heel sections. Two sets of elastic pillars are integrally formed on both sides of the top of the heel section of the lower pad, with the two rows of elastic pillars in each set staggered in opposite directions. Each row of elastic pillars is equidistant from each other, and all elastic pillars are inclined, with the forward-facing elastic pillars inclined at a 45° angle. The tops of several elastic pillars are integrally formed at the bottom of the lower pad. Several support pillars are integrally formed on the top of the forefoot section of the lower pad. This utility model can provide high elasticity while keeping the weight of the shoe sole at a low level, thereby increasing comfort during use.

[0004] This solution still has some shortcomings in its application. Since rubber soles must maintain high elasticity while also considering stability, including providing shock absorption and stable support during running and jumping, otherwise ankle sprains and injuries are likely to occur, which is detrimental to wearing safety. At the same time, abrasion resistance also needs to be considered. Many highly elastic rubber soles often have low abrasion resistance, which can lead to a short service life. Therefore, the structure of rubber used in shoes needs to be improved so that it not only has high elasticity, but also shock absorption, stable support and abrasion resistance, making it safe, comfortable to wear and with a long service life. Utility Model Content

[0005] This utility model discloses a highly elastic shock-absorbing rubber for shoes, the main purpose of which is to overcome the above-mentioned deficiencies and shortcomings of the existing technology.

[0006] The technical solution adopted in this utility model is as follows:

The footwear rubber body and the abrasion-resistant layer are bonded together with shoe adhesive, and the protrusion is adapted to be embedded in the diamond-shaped opening.

[0008] Furthermore, the rubber body of the shoe is made of rubber material with a density of 1.15 g / cm³.

[0009] Furthermore, the shock-absorbing and stabilizing support layer is made of PU material.

[0014] 1. This utility model uses rubber material to make the main body of the shoe sole, with a density of 1.15g / cm³, which is lower than that of ordinary shoe rubber, but makes the main body of the sole softer and more elastic, and has a better high elasticity effect.

[0017] 4. This utility model features a wear-resistant layer on the bottom of the shoe's rubber body. This layer, made of hard rubber with anti-slip texture, provides both wear resistance and slip resistance, overcoming the shortcomings of poor wear resistance in the original rubber body, which is prone to wear when in direct contact with the ground. Furthermore, a drainage channel is provided in the middle of the rubber body, allowing for timely drainage when water is involved. This utility model boasts a novel structure and ingenious design, combining high elasticity and shock absorption, making it suitable for use as a sole in sports shoes. Attached Figure Description
