Description

Technical Field

[0001] This utility model relates to the field of sneaker technology, and more specifically to anti-slip soles and sneakers. Background Technology

[0002] With the increasing demands for functionality in footwear products from sports and daily life, the anti-slip, cushioning, and breathability of soles have become key performance indicators. Currently, most athletic shoes or sneakers achieve anti-slip through simple rubber treads and cushioning through foam materials, while ventilation structures often lack a systematic design, leading to problems such as stuffiness, insufficient grip, or poor comfort during extended wear. Existing anti-slip designs are mostly unidirectional textured surfaces, making them prone to slipping during multi-directional movements; cushioning structures are often solid materials with limited cushioning capacity; and ventilation structures are mostly limited to upper ventilation, with insufficient consideration given to air circulation in the sole. Furthermore, the lack of a synergistic structure between the anti-slip and cushioning layers results in an imbalance in overall performance. Therefore, there is an urgent need for a more rationally structured and functionally integrated anti-slip sole and sneaker structure to improve the overall performance of footwear products. Utility Model Content

[0003] In view of this, the present invention provides a non-slip sole and a sneaker.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An anti-slip sole includes an upper cushioning layer and a lower anti-slip layer, wherein: the bottom of the lower anti-slip layer has multiple first anti-slip ribs corresponding to the forefoot and heel, the first anti-slip ribs having a cross-shaped structure with intersecting transverse and longitudinal protrusions; the outer edge of the bottom of the lower anti-slip layer has at least two continuous wave-shaped second anti-slip ribs, the second anti-slip ribs extending from the bottom edge of the lower anti-slip layer to its side, for enhancing the anti-slip performance of the outer edge of the sole; the upper cushioning layer has multiple transversely penetrating buffer holes inside; the upper cushioning layer also has multiple longitudinal ventilation holes, the bottom of the ventilation holes connecting to the buffer holes, and the top connecting to the upper surface of the upper cushioning layer, thereby forming an upward airflow path.

[0006] In the preferred technical solution, the first anti-slip rib extends 2-5 mm above the bottom surface of the lower anti-slip layer and is arranged in multiple rows to enhance multi-directional anti-slip performance.

[0007] In the preferred technical solution, the wave structure of the second anti-slip rib extends circumferentially along the outer edge of the lower anti-slip layer, and has an alternating wave crest and trough structure to improve the grip of the shoe sole edge.

[0008] In a preferred embodiment, the lower anti-slip layer is made of rubber or thermoplastic polyurethane, possessing wear resistance and high elasticity; the upper shock-absorbing layer is made of foam material, possessing lightweight, cushioning, and resilience properties. In another preferred embodiment, an intermediate support layer is provided between the upper shock-absorbing layer and the lower anti-slip layer, and an anti-torsion plate or carbon fiber sheet is embedded within the intermediate support layer.

[0009] In the preferred technical solution, the diameter of the buffer holes is 3 to 8 mm, and they are evenly distributed laterally throughout the entire area of ​​the upper damping layer.

[0010] A type of sneaker includes an upper and a non-slip sole, wherein the non-slip sole is fixedly connected to the upper by adhesive or injection molding to form a one-piece structure.

[0011] In the preferred technical solution, the bottom of the shoe upper is provided with multiple shoe upper openings, the shoe upper openings correspond to the ventilation holes on the anti-slip sole, and are used to connect the sole and the internal space of the shoe.

[0012] In a preferred embodiment, the shoe has an insole inside, and the insole has multiple insole openings that correspond to the ventilation holes and the openings on the upper, so as to form a through ventilation channel between the insole, the upper, and the sole.

[0013] In the preferred technical solution, the insole is a detachable structure, and the opening of the insole is provided with a microporous breathable membrane or dustproof mesh to allow air circulation while preventing foreign objects from entering the shoe.

[0014] As can be seen from the above technical solution, compared with the prior art, the present invention has the following beneficial technical effects:

[0015] The outsole features a cross-shaped first anti-slip rib, which not only enhances grip in the forefoot and heel areas but also adapts to force from different directions, preventing multi-directional slippage. The second anti-slip rib has a wave-shaped structure extending to the side of the outsole, enhancing lateral anti-slip performance and overall stability, making it particularly suitable for sports involving frequent changes of direction. The upper cushioning layer has transversely connected shock-absorbing holes, effectively dispersing impact force, reducing pressure on the feet, and improving wearing comfort. Vertical ventilation holes penetrate the cushioning layer and connect with corresponding openings in the upper and insole, forming a complete air circulation channel, significantly improving breathability and solving the problem of stuffiness inside the shoe. The clear structure of each layer allows for layered processing and overall assembly using mature processes such as standard molding, injection molding, and hot pressing, making it suitable for large-scale industrial production. The insole has ventilation openings and can be fitted with a dustproof mesh, balancing breathability and hygiene, facilitating replacement and cleaning, and enhancing the user experience.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0023] In the description of this application, it should be understood that the terms "longitudinal," "radial," "length," "width," "thickness," "upper," "lower," "left," "right," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0024] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0025] like Figure 1-4 As shown, the anti-slip sole and shoe include an upper cushioning layer 1, a lower anti-slip layer 2, an optional intermediate support layer 3, an upper 4 applied to the overall structure, and an insole 5 used in conjunction with it. The lower anti-slip layer 2 is the bottom layer of the sole, directly contacting the ground. Its structure and materials are designed to provide good anti-slip and grip performance. Specifically, multiple first anti-slip ribs 21 are provided in the forefoot and heel areas. These ribs are characterized by a cross-shaped raised structure, including a longitudinal rib and a transverse rib intersecting to form a cross, with multiple cross-shaped raised ribs distributed in a grid or row pattern. This structure can provide friction in multiple directions, making it particularly suitable for multi-directional sports such as basketball and running, improving the anti-slip ability during sports. The first anti-slip ribs 21 are preferably designed to protrude 2-5 mm above the bottom surface of the lower anti-slip layer 2 to ensure that contact and friction effects are maintained even on wet or uneven surfaces. At least two second anti-slip ribs 22 are provided on the outer edge of the sole, especially in the forefoot and midfoot side areas. These are wavy ribs that extend from the bottom to the sidewall along the edge of the sole, forming a wraparound structure. This design not only enhances the grip of the edges but also prevents lateral slippage and rollover during sudden stops and turns.

[0026] The second anti-slip rib 22 is preferably a continuous wave-shaped protrusion, in the form of an "S" shape or a sine wave, with a coherent structure and reasonable distribution, which improves the problem of easy slippage in the edge area of ​​traditional shoe soles.

[0027] Furthermore, the upper cushioning layer 1 is located in the middle layer of the sole, and its function is to provide cushioning and shock absorption when the foot lands. It is preferably made of foamed EVA material, which has the advantages of being lightweight and having good resilience. This cushioning layer has multiple cushioning holes 11 inside, which are horizontally interconnected, with a diameter of 3-8 mm, and are evenly distributed throughout different areas of the upper cushioning layer 1. The cushioning holes 11 are more densely packed in the pressure transmission areas of the sole, especially in the forefoot and heel areas, to improve cushioning and absorption performance. The upper cushioning layer 1 also has multiple ventilation holes 12, which are vertically connected, with the bottom connecting to the cushioning holes 11 and the top connecting to the upper surface of the cushioning layer, to allow air to circulate from the sole to the inner cavity of the shoe. An intermediate support layer 3 can be optionally provided between the upper cushioning layer 1 and the lower anti-slip layer 2. This support layer can be made of high-strength materials, such as TPU or glass fiber reinforced nylon, and has an embedded anti-torsion plate or carbon fiber sheet to improve the overall stability of the sole and prevent torsion and deformation of the sole during strenuous exercise.

[0028] Furthermore, the aforementioned anti-slip sole and upper 4 are combined to form an integrated shoe structure. Using bonding or injection molding processes, the upper 4 and sole are reliably connected to form a one-piece shoe body. The bottom of the upper 4 has multiple openings 41, arranged corresponding to the ventilation holes 12, allowing air channels formed inside the sole to flow into the shoe cavity, achieving breathability and sweat-wicking function for the feet and effectively reducing the humid and hot environment inside the shoe. A removable insole 5 is installed inside the shoe cavity, with multiple insole openings 51. These openings are positioned consistent with the ventilation holes 12 and the upper openings 41, forming a complete air convection channel from the sole to the shoe cavity.

[0029] To prevent dust and foreign objects from entering the shoes, the insole openings 51 can be covered with a microporous breathable membrane or dustproof mesh, which can filter while ensuring breathability, thereby improving wearing comfort and hygiene.

[0030] Furthermore, the shoe and sole structure provided by this invention, combining multi-directional cross-shaped anti-slip ribs, a wave-shaped edge structure, an integrated anti-slip and cushioning design, a ventilation system, and a stable support layer, not only improves the anti-slip and grip performance of the sole but also takes into account cushioning, shock absorption, breathability, comfort, and deformation resistance, making it particularly suitable for various high-intensity sports scenarios such as basketball, running, and training. This structure is easy to industrialize, with controllable material costs, and possesses good market promotion and application value. The anti-slip sole and shoe of this invention can be manufactured using the following process: the upper cushioning layer uses foamed EVA material, which is lightweight and has good resilience.

[0031] The lower anti-slip layer uses rubber or thermoplastic polyurethane (TPU) to ensure abrasion resistance and elasticity. The middle support layer uses nylon plates or carbon fiber sheets to enhance torsional stability. The upper is made of fabric or synthetic leather, and the insole is made of EVA or PU foam. The cushioning layer is molded or injection-molded, with cushioning holes and ventilation holes pre-set in the mold or processed later. The anti-slip layer is molded, with first and second anti-slip rib structures in the mold. The support layer is cut and placed between the cushioning layer and the anti-slip layer, and fixed by hot pressing or adhesive. The upper and lower layers are bonded by adhesive or injection molding, and reinforced by hot pressing if necessary to ensure unobstructed ventilation. Precise positioning of each structure is required to prevent misalignment or blockage of ventilation holes. The bottom of the upper has openings corresponding to the ventilation holes, which are connected to the sole by adhesive or injection molding. The insole has openings and is fitted with a breathable membrane or dustproof mesh, forming a complete ventilation channel inside the shoe. The finished product undergoes multiple tests, including anti-slip performance, shock absorption, and breathability, to ensure its performance meets the standards.

[0032] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
