Description

Technical Field

[0001] This utility model relates to the field of footwear technology, and in particular to a wear-resistant commuter shoe sole. Background Technology

[0002] In modern urban life, commuting scenarios cover a variety of complex road surfaces, including asphalt, concrete, slippery tiles, and light gravel. Consumers have higher requirements for the wear resistance, slip resistance, and environmental adaptability of shoe soles. In particular, for office workers and students who walk for long periods of time, the forefoot metatarsal area and the outer heel of the shoe sole are the areas that suffer the most wear due to high-frequency contact with the ground. At the same time, the need for slip resistance in wet and slippery environments also poses a challenge to the design of shoe sole patterns.

[0003] Currently, most durable commuter shoe soles on the market use a single material or a uniformly distributed abrasion-resistant material, achieving anti-slip functionality through simple geometric patterns on the outsole. However, this design has significant drawbacks: First, the uniform distribution of abrasion-resistant material results in a lack of targeted reinforcement in vulnerable areas such as the forefoot metatarsal area and the outer heel, leading to excessively rapid wear in certain areas under high-frequency friction, causing uneven overall sole lifespan. Second, traditional anti-slip patterns are mostly simple straight lines or grid structures, which are insufficient for drainage and mud removal on wet or muddy surfaces. Foreign objects accumulate in the gaps between the patterns, forming abrasive particles, which not only reduce the effective contact area between the sole and the ground but also accelerate wear on the contact surface. At the same time, the uniformity of friction in all directions of straight patterns is poor, making it difficult to adapt to gait changes on complex terrain.

[0004] Therefore, to address the aforementioned issues, a wear-resistant commuter shoe sole is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a wear-resistant commuter shoe sole, which aims to improve the problem that some existing wear-resistant commuter shoe soles have insufficient wear-resistant zones and poor drainage of anti-slip patterns, resulting in rapid wear in vulnerable areas.

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

[0007] A wear-resistant commuter shoe sole includes an outer shell, and the inner side of the outer shell is provided with an outsole wear-resistant layer, a midsole support layer and a base layer from bottom to top;

[0008] The outsole wear-resistant layer includes a metatarsal reinforcement area, a foot support area and a heel elastic area. The bottom of the metatarsal reinforcement area is embedded with silicon carbide wear-resistant particles arranged in a diamond shape, and the silicon carbide wear-resistant particles form an interlaced guide channel to guide water flow and silt discharge.

[0009] The foot support area includes a base, which is located at the bottom center of the outsole wear-resistant layer, and the base contains multiple support springs for providing foot support.

[0010] As a further description of the above technical solution:

[0011] The heel elastic zone includes a rubber layer one, which is located at the bottom rear end of the outsole wear-resistant layer. A memory alloy sheet is located at the bottom of the rubber layer one, and the shape of the memory alloy sheet is adapted to the curvature of the heel. A rubber layer two is located at the bottom of the memory alloy sheet, and a biomimetic texture is located at the bottom of the rubber layer two to improve the anti-slip performance.

[0012] As a further description of the above technical solution:

[0013] The midsole support layer includes an anti-torsion layer and a buffer layer. The bottom of the anti-torsion layer is located on top of the outsole wear-resistant layer, and the buffer layer is located on top of the anti-torsion layer. The top of the anti-torsion layer and the bottom of the buffer layer are serrated and interlock with each other.

[0014] As a further description of the above technical solution:

[0015] The buffer layer has multiple cylindrical ventilation channels inside to allow air to circulate inside the sole, and the top of the anti-torsion layer has multiple hollow weight-reducing holes to reduce the weight of the sole.

[0016] As a further description of the above technical solution:

[0017] The base layer includes a moisture-wicking layer and a breathable layer. The moisture-wicking layer is placed on top of the buffer layer, and the breathable layer is placed on top of the moisture-wicking layer. The moisture-wicking layer and the breathable layer work together to conduct and dissipate sweat from the feet.

[0018] As a further description of the above technical solution:

[0019] The top of the breathable layer is provided with honeycomb-shaped breathable channels to increase the breathable area, and the top shape of the moisture-wicking layer is adapted to the shape of the honeycomb-shaped breathable channels.

[0020] As a further description of the above technical solution:

[0021] The shape memory alloy sheet is arc-shaped, and its shape conforms to the curve of the heel. The biomimetic pattern is a central cylindrical shape with radial patterns around it.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this invention, the differentiated wear resistance and adaptability to complex environments are improved through the partitioned reinforcement structure and biomimetic texture design of the outsole wear-resistant layer. The rhomboid silicon carbide particle wear-resistant sheet embedded in the metatarsal reinforcement area, together with the drainage channel, effectively resists high-frequency friction in the forefoot and quickly drains water and sand, reducing wear on the contact surface; the gradient hardness rubber layer on the outer side of the heel disperses the impact force layer by layer, combined with the arc-shaped memory alloy sheet to dynamically adapt to the ankle dorsiflexion, evenly distributing the wear area; the full-length biomimetic spiral pattern and dovetail-shaped drainage channel enhance the friction in all directions and optimize the drainage path, improving stability on wet and slippery surfaces, thereby improving the wear resistance of the entire outsole.

[0024] 2. In this invention, dynamic mechanical support and optimization of the shoe's internal microenvironment are achieved through the wave-shaped anti-torsion structure of the midsole support layer and the moisture-wicking and breathable design of the base layer. The wave-shaped TPU anti-torsion layer conforms to the arch curve of the foot and, in conjunction with the hollowed-out weight-reducing holes, enhances torsional stiffness while reducing the weight of the sole; the upper EVA cushioning layer has built-in honeycomb-shaped breathable channels, which work in conjunction with the convex pillar moisture-wicking structure on the base layer to quickly conduct foot sweat and dissipate it through the honeycomb channels, keeping the inside of the sole dry; the support spring in the arch support area continuously provides arch support, reducing walking fatigue and improving comfort and stability during long-term wear.

[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 to 5 The present invention provides an embodiment of a wear-resistant commuter shoe sole, comprising an outer shell 1. The outer shell 1, as the outermost structure of the sole, is made of thermoplastic elastomer to form an integral closed protective shell, which provides physical protection for the inner outsole wear-resistant layer 2, midsole support layer 3 and base layer 4, resisting external impacts and abrasions, while giving the sole overall structural strength and ensuring the morphological stability when the functional layers work together. The inner side is provided with the outsole wear-resistant layer 2, midsole support layer 3 and base layer 4 in sequence from bottom to top.

[0034] The outsole abrasion layer 2 includes a metatarsal reinforcement zone 21, a foot support zone 22, and a heel elastic zone 23. The bottom of the metatarsal reinforcement zone 21 is embedded with diamond-shaped silicon carbide abrasion-resistant particles. Utilizing the high hardness of the silicon carbide particles, it specifically resists the high-frequency friction between the forefoot and the ground during walking, reducing the direct wear of the rubber material in this area and extending the service life of the forefoot of the sole. In addition, the silicon carbide abrasion-resistant particles form staggered drainage channels. Through the channel structure, water, mud, sand, and other foreign objects brought in during walking are guided to be discharged along the channels to the edge of the sole, preventing foreign objects from accumulating on the contact surface and forming abrasive particles. This increases the direct contact area between the sole and the ground on wet and slippery surfaces, improving the coefficient of friction and walking stability.

[0035] The arch support area 22 includes a base 221, which is located in the middle of the bottom of the outsole wear layer 2. It is made of rigid material and provides a mounting carrier for the internal support springs 222, ensuring the stability of the support structure and the uniformity of force transmission. Multiple support springs 222 are installed inside the base 221. The multiple springs are distributed inside the base 221 along the arch curve. When walking, they are compressed and deformed with the pressure of the foot hitting the ground, absorbing the impact force of the ground. Then, they provide continuous arch support force through rebound, balancing the force on the arch area, reducing gait abnormalities and uneven wear of the sole caused by arch collapse, and enhancing the overall stability of the sole.

[0036] The heel elastic zone 23 includes a rubber layer 231, which is located at the bottom rear end of the outsole wear-resistant layer 2. Made of medium-hardness rubber, it serves as the upper cushioning carrier for the shape memory alloy sheet 232, absorbing the initial impact force when the heel lands and reducing the direct vibration of the hard shape memory alloy sheet 232 on the foot. The bottom of the rubber layer 231 contains the shape memory alloy sheet 232, made of nickel-titanium alloy. The sheet is curved to fit the natural curvature of the heel and has shape memory function. When the heel lands, it undergoes elastic deformation, dispersing the impact force to the rubber layer 231 and the rubber layer 233. When the foot is lifted, the impact force is dispersed through the rubber layer 231 and the rubber layer 233. The shoe rebounds and returns to its original shape, dynamically adapting to ankle dorsiflexion movements, enhancing the elastic cushioning effect in the heel area, reducing abnormal wear on the outer side of the heel, and thus enhancing heel elasticity. The bottom of the memory alloy plate 232 is equipped with a second rubber layer 233, which is located at the bottom of the memory alloy plate 232. The second rubber layer 233 is made of wear-resistant rubber material and has a biomimetic pattern 234 on its bottom. The biomimetic pattern 234 is a central cylindrical shape with radial patterns around it. By increasing the contact area between the sole and the ground, it improves the friction in all directions, especially in complex terrain, effectively preventing slippage. At the same time, it disperses the pressure when the heel lands, evens out the wear area, and improves the anti-slip performance.

[0037] The midsole support layer 3 includes an anti-torsion layer 31 and a cushioning layer 32. The bottom of the anti-torsion layer 31 is located on top of the outsole abrasion-resistant layer 2, and the cushioning layer 32 is located on top of the anti-torsion layer 31. The top of the anti-torsion layer 31 and the bottom of the cushioning layer 32 are serrated and interlocked. The peak and trough structure enhances the mechanical connection strength of the two layers, limits excessive torsion of the sole, improves torsional stiffness, ensures synchronous movement of the arch and sole during walking, reduces gait deviation and local wear caused by sole deformation, enhances the connection stability between the anti-torsion layer 31 and the cushioning layer 32, and improves the torsional performance of the sole. Multiple cylindrical ventilation channels are formed inside the cushioning layer 32. These channels run through the upper and lower surfaces of the cushioning layer 32 and are evenly distributed along the arch curve of the foot. When walking, they generate a pumping effect with the movement of the foot, promoting air circulation inside the sole. The heat and moisture generated by the foot are conducted upward to the base layer 4 through the channels, keeping the inside of the sole dry and reducing the adverse effects of a hot and humid environment on the foot. This achieves air circulation inside the sole and keeps the feet dry. The top of the anti-torsion layer 31 has multiple hollow weight-reducing holes. These holes are distributed on the top of the anti-torsion layer 31. By removing materials from non-critical stress areas, the weight of the sole is reduced without affecting the structural strength, improving the lightness of wearing. At the same time, they form air circulation channels, assisting the breathability of the cushioning layer 32, reducing the weight of the sole, and improving wearing comfort.

[0038] The base layer 4 includes a moisture-wicking layer 41 and a breathable layer 42. The bottom of the moisture-wicking layer 41 is set on top of the buffer layer 32, and the breathable layer 42 is set on top of the moisture-wicking layer 41. The moisture-wicking layer 41 and the breathable layer 42 work together. The bottom of the moisture-wicking layer 41 is connected to the groove on the top surface of the buffer layer 32 through a convex post moisture-wicking structure. It quickly receives the foot sweat conducted by the buffer layer 32. The fine grooves on the surface of the convex post collect the sweat in the direction of the breathable layer 42, realizing the initial conduction of sweat from the foot to the outside of the sole, and realizing the conduction and dissipation of foot sweat. The top of the breathable layer 42 is provided with honeycomb-shaped breathable channels. The honeycomb-shaped microstructure at the top of the breathable channels greatly increases the breathable surface area. Utilizing the efficient conduction characteristics of the honeycomb hexagonal structure, the sweat transported by the moisture-wicking layer 41 is quickly dissipated to the external environment, while allowing fresh air from the outside to enter the inside of the sole. This maintains the air circulation and humidity balance of the microenvironment inside the shoe, improves the comfort of wearing for a long time, increases the breathable area, and enhances the breathability. The top shape of the moisture-wicking layer 41 is adapted to the shape of the honeycomb-shaped breathable channels to better realize the moisture-wicking function.

[0039] Working Principle: When people walk, the outsole abrasion layer 2 first directly contacts the ground, undertaking the main tasks of abrasion resistance and anti-slip. In the metatarsal reinforcement area 21, the diamond-shaped silicon carbide abrasion-resistant particles embedded at the bottom can effectively resist the friction between the forefoot and the ground, extending the service life of the sole. The staggered drainage channels between the abrasion-resistant particles can quickly guide water or mud out when they encounter water or mud, preventing accumulation on the sole, thereby enhancing stability in slippery environments and ensuring walking safety. Multiple support springs 222 are set inside the base 221 of the arch support area 22. During walking, as the pressure of the foot changes, the support springs 222 will compress and rebound, providing continuous support to the arch of the foot, effectively enhancing the overall stability of the sole and reducing fatigue during walking.

[0040] In the heel elastic zone 23, rubber layer 1 231, shape memory alloy sheet 232, and rubber layer 233 work together. The shape memory alloy sheet 232 is arc-shaped, perfectly conforming to the curve of the heel. When the heel lands, the shape memory alloy sheet 232 deforms due to force and then quickly rebounds, enhancing the elasticity of the heel and providing a comfortable cushioning effect. The biomimetic pattern 234 on the bottom of rubber layer 233, with its unique central cylindrical shape and surrounding radial pattern design, increases the contact area between the sole and the ground, thereby improving friction and preventing slippage during walking. The midsole support layer 3 plays a role in stability and comfort during walking. The anti-torsion layer 31 and the cushioning layer 32 work closely together. Multiple cylindrical ventilation channels inside the cushioning layer 32 allow air circulation inside the sole as the foot moves during walking, keeping the feet dry and preventing stuffiness and dampness. Multiple hollow weight-reducing holes at the top of the anti-torsion layer 31 reduce the overall weight of the sole, making it lighter to wear without affecting its structural strength. The serrated interlocking structure between the anti-torsion layer 31 and the cushioning layer 32 enhances the connection stability between the two, improves the anti-torsion performance of the sole, and makes the foot movements more stable and coordinated during walking.

[0041] The moisture-wicking layer 41 and the breathable layer 42 of the base layer 4 work together. The bottom of the moisture-wicking layer 41 is connected to the top of the cushioning layer 32. When sweat is produced on the feet, the moisture-wicking layer 41 quickly conducts the sweat to the breathable layer 42. The honeycomb-shaped ventilation channels at the top of the breathable layer 42 greatly increase the ventilation area, allowing sweat to quickly dissipate to the outside and keep the feet dry and comfortable. Throughout the walking process, the outer shell 1, as the outermost layer, protects the inner outsole wear-resistant layer 2, midsole support layer 3, and base layer 4, while also providing a certain degree of overall structural strength to the sole. All parts work together to ensure the wearer's comfort and safety during commuting, meeting the diverse performance needs of daily commuting.
