Abstract
Description
Technical Field
[0001] This utility model relates to the field of shock-absorbing shoe technology, and in particular to a non-slip shock-absorbing shoe sole. Background Technology
[0002] As the only part of footwear in direct contact with the ground, the sole bears multiple core functions, including supporting body weight, cushioning foot impact, and providing grip. During daily walking and various sports activities, the feet are constantly subjected to impact forces from the ground, while also coping with varying ground conditions such as dry and slippery surfaces. Therefore, the shock absorption and slip resistance of the sole directly affect the wearer's comfort, joint health, and even personal safety. Developing a sole structure that can simultaneously achieve efficient shock absorption and reliable slip resistance has significant practical value and market demand.
[0003] In existing technologies, traditional shoe sole structures typically consist of a midsole and an outsole, focusing on shock absorption and slip resistance, respectively. For shock absorption, the technology primarily relies on the physical properties of the midsole material itself. Common midsoles use a single elastic foam material, such as EVA (ethylene-vinyl acetate copolymer) or PU (polyurethane), which absorbs impact through material deformation under pressure. Some athletic shoes further incorporate a simple air cushion or gel block in specific areas of the midsole (such as the heel) to enhance localized cushioning. For slip resistance, the technology depends on the outsole material and tread pattern design. Outsoles are usually made of abrasion-resistant rubber materials, with various grooves, blocks, or wavy patterns molded onto the surface in contact with the ground. This aims to increase friction by increasing the roughness of the contact surface and providing drainage pathways.
[0004] However, this design, which simply separates and stacks shock absorption and anti-slip functions, reveals significant performance shortcomings in practical use, making it difficult to simultaneously meet the high standards required in complex environments. On the one hand, while single EVA or PU foam materials offer some initial cushioning, they are prone to permanent deformation (compression setting) after repeated pressure, leading to a rapid decline in shock absorption performance and failing to provide lasting and effective protection for the ankles and knees. On the other hand, traditional outsole anti-slip patterns are often shallow, resulting in insufficient drainage when facing wet or oily surfaces. This easily creates a "water film" between the sole and the ground, drastically reducing grip and posing a high risk of slipping. Ultimately, existing technology fails to systematically integrate the two core functions of shock absorption and anti-slip, lacking a collaborative composite system. This results in a trade-off between durable shock absorption and reliable anti-slip, failing to provide users with all-weather, comprehensive safety protection. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an anti-slip and shock-absorbing shoe sole, which aims to improve the problem that although EVA or PU foam materials have a certain initial cushioning effect, they are prone to permanent deformation (i.e., "compression setting") after repeated pressure, resulting in rapid decay of shock absorption performance and failure to provide lasting and effective protection for the foot, ankle and knee joints.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: a non-slip and shock-absorbing shoe sole, comprising:
[0007] The sole body has at least one shock-absorbing chamber inside;
[0008] A honeycomb-shaped shock-absorbing core is disposed within the shock-absorbing chamber;
[0009] The wear-resistant outer bottom layer is attached to the bottom of the main body of the sole, and the ground surface of the wear-resistant outer bottom layer is provided with crisscrossing water-guiding grooves and at least one anti-slip block.
[0010] As a further description of the above technical solution:
[0011] The honeycomb-shaped shock-absorbing core is integrally molded from a highly elastic thermoplastic polyurethane material.
[0012] As a further description of the above technical solution:
[0013] The heel of the main body of the sole is also provided with a heel shock-absorbing airbag, which works together with the honeycomb shock-absorbing core.
[0014] As a further description of the above technical solution:
[0015] The anti-slip block is made of a soft rubber material with a higher coefficient of friction than the wear-resistant outer bottom layer material, and is fixed in the wear-resistant outer bottom layer by embedding.
[0016] As a further description of the above technical solution:
[0017] The main body of the sole has an integrated arch support structure embedded in the middle.
[0018] As a further description of the above technical solution:
[0019] The arch support structure is a rigid nylon plate or carbon fiber plate, used to provide torsional support.
[0020] As a further description of the above technical solution:
[0021] The wear-resistant outer layer has several elastic protrusions in the forefoot area to enhance the rebound feedback during startup.
[0022] As a further description of the above technical solution:
[0023] The top of the sole body is also provided with a connecting layer, which is used to bond or sew it to the upper.
[0024] This utility model has the following beneficial effects:
[0025] This invention constructs a composite shock absorption system by combining a honeycomb-shaped shock-absorbing core with a heel shock-absorbing airbag. This system not only effectively absorbs and disperses the vertical impact force generated during walking or exercise, but also provides continuous cushioning support through the elastic deformation of the honeycomb structure, significantly reducing the risk of injury to the user's ankles, knees, and other joints. Simultaneously, the synergistic design of the deep water-guiding channels on the wear-resistant outsole and the embedded high-friction coefficient anti-slip sliders provides stable grip on dry surfaces and rapid water drainage on wet surfaces, while the anti-slip sliders ensure friction in the core contact area. This greatly enhances the anti-slip safety of the sole in varying environments, achieving an organic unity of shock absorption and anti-slip stability. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figures 1-4 One embodiment of this utility model provides: an anti-slip and shock-absorbing shoe sole, comprising:
[0034] The sole body 1 serves to form the middle layer of the sole (i.e., the midsole), providing basic support and shaping for the foot, and acting as a base for supporting other functional components; the sole body 1 has at least one shock-absorbing chamber 4 inside; its function is to reserve precise space inside the sole to accommodate and position the core shock-absorbing components.
[0035] The honeycomb-shaped shock-absorbing core 5 is designed to efficiently absorb and disperse impact forces by undergoing elastic deformation under pressure. The honeycomb-shaped shock-absorbing core 5 is installed inside the shock-absorbing chamber 4. Its function is to ensure that the shock-absorbing core is stably placed in the area that needs the most cushioning.
[0036] The wear-resistant outsole 3 is combined with the bottom of the main body of the sole 1. Its function is to serve as the outsole that directly contacts the ground, providing durability and grip. The ground contact surface of the wear-resistant outsole 3 is provided with crisscrossing water channels 7 and at least one anti-slip block 8, which together form a composite anti-slip system to cope with different road conditions.
[0037] The honeycomb-shaped shock-absorbing core 5 is integrally molded from high-elasticity thermoplastic polyurethane (TPU) material. Its function is to utilize the excellent resilience, tear resistance, and fatigue resistance of TPU to ensure that the shock-absorbing structure is not easily damaged even after long-term repeated pressure. A heel shock-absorbing airbag 6 is also located at the heel of the main sole 1. Its function is to provide additional, powerful cushioning protection at the heel area where the foot experiences the greatest impact. The heel shock-absorbing airbag 6 and the honeycomb-shaped shock-absorbing core 5 work together to form a composite shock-absorbing system. The airbag absorbs instantaneous large impacts, while the honeycomb core provides continuous support and energy dispersion. The anti-slip block 8 is made of a soft rubber material with a higher coefficient of friction than the main material of the wear-resistant outsole 3. Its function is to create high-friction areas at key contact points to improve anti-slip performance while ensuring the overall wear resistance of the outsole. It is embedded in the wear-resistant outsole 3, ensuring that the soft anti-slip block can be firmly bonded to the outsole. To prevent the sole from falling off during use, an integrated arch support structure 9 is embedded in the middle of the main sole 1. Its function is to provide rigid support for the arch area of the foot and prevent excessive pronation or supination. The arch support structure 9 is made of rigid nylon or carbon fiber plate to provide anti-torsional support. Its function is to enhance the rigidity of the middle of the sole and resist the torsion of the sole during walking or sports, thereby improving the stability of the entire shoe. The forefoot area of the wear-resistant outsole 3 is provided with several forefoot elastic protrusions 10. Its function is to provide better flexibility and energy feedback in the area where the forefoot flexes and exerts force, and to enhance the rebound feedback during start-up. Its function is to allow the wearer to feel a propulsive force when pushing off the ground, thereby improving athletic performance. The top of the main sole 1 is also provided with a connecting layer 2, which serves as the interface layer between the main sole and the upper. The connecting layer 2 is used to bond or sew with the upper, and its function is to ensure that the sole and the upper can be firmly combined into a whole.
[0038] Working Principle: When using this anti-slip and shock-absorbing sole, shock-absorbing chambers 4 are created in the key stress areas of the heel and midsection of the sole body 1, filled with honeycomb-shaped shock-absorbing cores 5 made of TPU material. When the foot lands, the impact force is first transmitted from the wear-resistant outsole 3 to the sole body 1 and then quickly dispersed to the honeycomb-shaped shock-absorbing cores 5. This honeycomb structure, through the elastic deformation of its geometric shape, efficiently converts the concentrated impact force into energy absorption and dissipation, achieving excellent cushioning effect. In particular, an additional heel shock-absorbing airbag 6 is set in the heel area where the impact force is greatest, forming double shock absorption protection. The anti-slip function is achieved by the precise design of the wear-resistant outsole 3. The surface of the outsole 3 is covered with crisscrossing water-guiding channels 7. When in contact with a wet and slippery surface, these channels can quickly drain water from the main stress areas, disrupting the formation of a water film. At the same time, anti-slip blocks 8 made of soft rubber with a higher coefficient of friction are embedded in key stress points of the sole, such as the forefoot and the outer side of the heel. Once the drainage channels drain the water, these anti-slip blocks 8 can form a stronger physical contact with the ground, thereby generating strong grip and effectively preventing slips. The rigid arch support structure 9 embedded in the middle of the sole provides good torsional resistance and support, preventing excessive arch collapse. Meanwhile, the elastic forefoot protrusion 10 at the front of the abrasion-resistant outsole 3 can provide a certain amount of propulsion when the user pushes off the ground, making the gait lighter and more efficient.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
