Anti-skid claw for shoes and anti-skid sole

Abstract

The utility model provides a kind of shoe with antiskid claw and antiskid sole, and antiskid claw main body is overturned by the unified pivot formed by first pivot and second pivot, so that the non-working surface of antiskid claw main body is exposed and is in the non-antiskid use state of ordinary wearing, or the working surface of antiskid claw main body with antiskid nail is exposed and is in the antiskid use state. The nail clamp head is matched and embedded into the fixed nail hole, and the fixed nail hole is used to clamp the nail clamp head to fix the position firmly, so as to avoid the antiskid nail from falling off and shaking. The second radial protrusion is clamped outside the shrinkage wall of the fixed nail hole, so as to avoid the antiskid nail from being pressed against the reaction force of the ground, shrinking into the fixed nail hole, or even being pressed through the back sealing stop part to lose the antiskid effect. The back sealing stop part can also be reinforced on the back of the clamp head. The above structure can limit and fix the antiskid nail in all directions, so as to ensure long-term durability. At the same time, the sharp structure of the exposed section is more conducive to the embedding of the antiskid nail into the ice surface and other hard and slippery road surfaces, ensuring the antiskid effect.

[0002] Shoes are an indispensable part of people's daily lives. The origin and development of shoes are inseparable from the natural environment. With the development of technology, the functions of shoes have become more and more perfect. However, at present, in special outdoor environments such as icy and snowy roads or mountains in high latitudes and some high-altitude areas, existing shoes, including most mountaineering shoes, cannot achieve reliable and effective anti-slip effects and safety guarantees. This brings many inconveniences and even safety hazards to the normal life of people living and active in such special environments.

[0003] To address this issue, Chinese utility model patent CN201020263146.2 discloses a novel anti-slip shoe sole, comprising a sole body, an anti-slip block on the bottom surface of the sole body, and an anti-slip device. The anti-slip device consists of a fixing plate and an anti-slip plate. The fixing plate is fixed to the bottom surface of the sole body, and the anti-slip plate is hinged to the fixing plate in a flip-backward manner. One side of the anti-slip plate has serrated anti-slip teeth, the tips of which protrude beyond the anti-slip block in the thickness direction of the sole body. The bottom surface of the sole body has a positioning mechanism for the anti-slip plate to adhere to and a receiving groove for accommodating the anti-slip teeth. A locking block protrudes from the side of the anti-slip plate, and fixing holes for the locking block to engage are provided on the front and rear sides of the bottom surface of the sole body.

Furthermore, a second radial protrusion engages outside the constricted hole wall, preventing the studs from being pushed back into the fixed stud holes or even pierced through the back seal by the reaction force of stepping on the ground, thus preventing loss of anti-slip effect. The back seal is also reinforced on the back of the stud head. This multi-directional locking structure provides comprehensive positioning and fixation of the anti-slip studs, ensuring durability. The exposed pointed ends further facilitate the studs' embedding into hard, slippery surfaces such as ice, ensuring continued anti-slip performance. Compared to existing technologies, this invention provides superior outdoor anti-slip properties on ice and snow, as well as safety, practicality, and durability.

This exposes the non-working surface of the anti-slip claw body in a normal non-anti-slip use state, or exposes the working surface of the anti-slip claw body with anti-slip studs in an anti-slip use state, so that safe anti-slip activities can be carried out on slippery outdoor surfaces such as ice and snow. To achieve practicality, durability, and enhanced anti-slip properties, multiple anti-slip studs are constructed using wear-resistant reinforced alloys and other metal materials, and are integrally injection molded from high-strength resin.

Detailed Implementation

[0049] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0050] This utility model relates to a shoe anti-slip claw, such as... Figure 1-14As shown, the device includes an anti-slip claw body 1; the anti-slip claw body 1 includes a first connecting section 11 and a second connecting section 12 connected to the sole body 2; the first connecting section 11 is provided with a first mounting component 111 connected to the sole body 2, and the second connecting section 12 is provided with a second mounting component 121 connected to the sole body 2; the first connecting section 11 and the first mounting component 111 are pivotally connected together by a first pivot 112, and the second connecting section 12 and the second mounting component 121 are pivotally connected together by a second pivot 122; the first pivot 112 and the second pivot 122 share the same axis; the anti-slip claw body 1 has an anti-slip working surface and non-working surfaces facing opposite directions, and the anti-slip working surface has a plurality of protruding and parallel anti-slip studs 3; the anti-slip studs 3 are made of metal, the anti-slip claw body 1 is made of resin, and the anti-slip studs 3 and the anti-slip claw body 1 are integrally injection molded; the anti-slip studs 3 have embedded anti-slip claws... The anti-slip claw body 1 has an embedded section 31 inside and an exposed section 32 outside the anti-slip claw body 1. The embedded section 31 includes a nail head 311 that is locked inside the anti-slip claw body 1 and a nail transition section 312 connecting the nail head 311 and the exposed section 32. The nail head 311 is a first radial protrusion that protrudes radially along the anti-slip nail 3. The anti-slip claw body 1 has a nail fixing hole that matches the nail head 311 and the nail transition section 312. The nail head 311 has a front face 3111 facing the nail transition section 312 and a back face 3112 facing the opposite direction. The anti-slip claw body 1 has a constricted hole wall 13 that is locked on the front face 3111 and a back sealing portion 14 that is sealed on the back face 3112. The exposed section 32 includes a second radial protrusion 321 that is locked on the outside of the constricted hole wall 13 and protrudes radially along the anti-slip nail 3. The constricted hole wall 13 is located between the first radial protrusion and the second radial protrusion 321. In actual installation and use, the first connecting section 11 and the second connecting section 12 of the anti-slip claw body 1 face the sole body 2 and are connected to the sole body 2 through the first mounting component 111 and the second mounting component 121, respectively. The first connecting section 11 and the first mounting component 111 are connected to each other in a rotatable pivotal manner through the first pivot 112, and the second connecting section 12 and the second mounting component 121 are connected to each other in a rotatable pivotal manner through the second pivot 122. Moreover, the first pivot 112 and the second pivot 122 are coaxially arranged, so that the entire anti-slip claw body 1 can be rotated by the unified pivot formed by the first pivot 112 and the second pivot 122, so that the non-working surface of the anti-slip claw body 1 is exposed and in a non-anti-slip use state for normal wear, or so that the working surface of the anti-slip claw body 1 with the anti-slip studs 3 is exposed and in an anti-slip use state, so that safe anti-slip activities can be carried out on smooth outdoor surfaces such as ice and snow.To achieve practicality, durability, and enhanced anti-slip effects, multiple anti-slip studs 3 are constructed using wear-resistant reinforced alloys and other metal materials, and are integrally injection molded from high-strength resin. The stud head 311 is matched and embedded in the fixed stud hole, and the constricted hole wall 13 of the fixed stud hole securely positions the stud head 311, preventing the anti-slip studs 3 from falling off or shaking. Furthermore, the second radial protrusion 321 is secured to the outside of the constricted hole wall 13, preventing the anti-slip studs 3 from being pushed back into the fixed stud hole or even pierced through the back seal 14 by the reaction force of stepping on the ground, thus preventing loss of anti-slip effect. The back seal 14 can also be reinforced with a stop on the back of the stud head 3112. In short, this multi-directional locking structure provides all-around positioning and fixation for the anti-slip studs 3, ensuring durability. Simultaneously, the pointed structure of the exposed section 32 is more conducive to the anti-slip studs 3 embedding into hard, slippery surfaces such as ice, ensuring the anti-slip effect. Specifically, the transition section 312 gradually tapers from the exposed section 32 to the nail head 311. The tapering structure of the transition section 312 allows for better fitment of the constricted hole wall 13, resulting in a thicker structure and a tighter, stronger nesting of the anti-slip studs 3. Simultaneously, the pointed structure of the exposed section 32 facilitates the embedding of the anti-slip studs 3 into hard, slippery surfaces such as ice, ensuring the anti-slip effect. To ensure the anti-slip effect and strength of the anti-slip studs 3, the transition section 312 gradually tapers from the exposed section 32 to the nail head 311. The nail head 311 is a circular plate perpendicular to the transition section, while the exposed section 32 is conical or frustum-shaped. The back seal 14 has a thickened protrusion on its surface, making it less likely for the nail head 311 to penetrate it. The nail head 311 can be disc-shaped, with a flat back surface 3112, further ensuring that the back seal 14 is not easily penetrated. The anti-slip stud 3 can be made of high-strength wear-resistant alloy materials such as manganese alloy and chromium alloy, while the anti-slip claw body 1 can be made of high-toughness resin materials such as nylon and PC.

[0051] To facilitate the cooperation between the first connecting segment 11 and the first rotating shaft 112, the second connecting segment 12 and the second rotating shaft 122, and the coaxial cooperation between the first rotating shaft 112 and the second rotating shaft 122, the specific structure can be as follows: the first connecting segment 11 has a first inner side facing the second connecting segment 12, and the second connecting segment 12 has a second inner side facing the first connecting segment 11; the first rotating shaft 112 is disposed on the first inner side and faces the second connecting segment 12, and the second rotating shaft 122 is disposed on the second inner side and faces the first connecting segment 11. To ensure structural strength, the first rotating shaft 112 and the first connecting segment 11 are integrally injection molded, and the second rotating shaft 122 and the second connecting segment 12 are integrally injection molded, both made of resin. Furthermore, the first mounting component 111 has a first shaft hole 1111 that mates with the first rotating shaft 112, and the second mounting component 121 has a second shaft hole 1211 that mates with the second rotating shaft 122. The tension between the first connecting segment 11 and the second connecting segment 12 can be used to maintain the fit between the first rotating shaft 112 and the first shaft hole 1111, and the fit between the second rotating shaft 122 and the second shaft hole 1211. Specifically, the first shaft hole 1111 and the second shaft hole 1211 are both through holes; the first rotating shaft 112 has a first shaft root end connected to the first connecting segment 11 and a first shaft mating end passing through the first shaft hole 1111; the second rotating shaft 122 has a second shaft root end connected to the second connecting segment 12 and a second shaft mating end passing through the second shaft hole 1211; the first shaft hole 1111 has a first hole outer end facing the first connecting segment 11 and a first hole inner end facing the second connecting segment 12, and the first shaft mating end forms a first shaft chuck 1121 that radially protrudes and locks into the inner end of the first hole; the second shaft hole 1211 has a second hole outer end facing the second connecting segment 12 and a second hole inner end facing the first connecting segment 11, and the second shaft mating end forms a second shaft chuck 1221 that radially protrudes and locks into the inner end of the second hole. This structure utilizes the opposing tension of the first connecting section 11 and the second connecting section 12 to maintain the snap-fit ​​engagement between the first shaft clamp 1121 and the first shaft hole 1111, and the second shaft clamp 1221 and the second shaft hole 1211. Each engagement structure is robust and stable, preventing disengagement. The inner end of the first hole has a first hole step 11111 for the first shaft clamp 1121 to engage, and the inner end of the second hole has a second hole step 12111 for the second shaft clamp 1221 to engage. The inner end of the first hole has a first receiving groove 11112 for accommodating the first shaft clamp 1121, and the inner end of the second hole has a second receiving groove 12112 for accommodating the second shaft clamp 1221. This structure protects the first shaft clamp 1121 and the second shaft clamp 1221, preventing them from wearing out and disengaging during use. For ease of installation, the outer end of the first hole has a chamfered bevel 11113 for the first shaft clamp 1121 to be smoothly inserted, and the outer end of the second hole has a chamfered bevel 12113 for the second shaft clamp 1221 to be smoothly inserted.The chamfered bevel 11113 of the first hole facilitates the first shaft clamp 1121 to be smoothly squeezed into the first shaft hole 1111 from the outer end of the first hole, and the chamfered bevel 12113 of the second hole facilitates the second shaft clamp 1221 to be smoothly squeezed into the second shaft hole 1211 from the outer end of the second hole.

[0052] To facilitate the installation and connection of the anti-slip claws to the sole body 2, the first mounting component 111 has a first connecting portion 113 that connects to the sole body 2, and the first connecting portion 113 has a first connector that radially protrudes and engages with the first mounting groove 24 of the sole body 2; the second mounting component 121 has a second connecting portion 123 that connects to the sole body 2, and the second connecting portion 123 has a second connector that radially protrudes and engages with the second mounting groove 25 of the sole body 2. The first connecting segment 11 is fixed in the first mounting groove 24 of the sole body 2 by the first mounting component 111 using the first connector, and the second connecting segment 12 is fixed in the second mounting groove 25 of the sole body 2 by the second mounting component 121 using the second connector, making installation convenient and secure. To further ensure convenient installation, the first connector is a convex head integrally formed on the first connecting part 113 and protruding radially, and the first connector has a first head slope 1131 that smoothly guides into the first mounting groove 24 of the shoe sole body 2; the second connector is a convex head integrally formed on the second connecting part 123 and protruding radially, and the second connector has a second head slope 1231 that smoothly guides into the second mounting groove 25 of the shoe sole body 2.

[0053] To maintain the stability of the anti-slip claw's position and working state relative to the sole body 2, the anti-slip claw body 1 has a claw positioning part 15 that engages with and is positioned in conjunction with the bottom positioning part of the sole body 2. Specifically, the anti-slip claw body 1 has a pivot end that is pivotally connected to the sole body 2 and a free end away from the pivot end. A first connecting section 11 and a second connecting section 12 are located at the pivot end. The free end has an inner claw surface facing the pivot end, and the claw positioning part 15 is integrally formed on the inner claw surface and protrudes towards the pivot end. If the anti-slip claw is located on the sole's forefoot of the sole body 2, when the anti-slip claw is flipped to the working state, the claw positioning part 15 protruding towards the pivot end engages with the forefoot working positioning part 261 to maintain the anti-slip claw in the working state; when the anti-slip claw is flipped to the non-working state, the claw positioning part 15 engages with the forefoot non-working positioning part 262 to maintain the anti-slip claw in the non-working state. If the anti-slip claw is located on the heel of the sole body 2, when the anti-slip claw is flipped to the working state, the claw positioning part 15 protruding towards the pivot end and the working positioning part 263 of the heel are used to lock the anti-slip claw in the working state; when the anti-slip claw is flipped to the non-working state, the claw positioning part 15 and the non-working positioning part 264 of the heel are used to lock the anti-slip claw in the non-working state. For easy installation, the claw positioning part 15 has a retaining slope 151 for the claw positioning part 15 to smoothly engage with the bottom positioning groove. The claw positioning part 15 can be easily engaged with the bottom positioning groove using the retaining slope 151. Furthermore, the non-working surface has a protrusion 16. When the anti-slip claw of the shoe is flipped to the non-working state and stored in the non-working receiving groove 22 of the sole body 2, the user can step on the ground to push against the protrusion 16, so that the anti-slip claw body 1 is kept in the non-working receiving groove 22 and the claw positioning part 15 is locked together with the bottom positioning groove, making it difficult to come off.

[0054] A type of non-slip shoe sole, such as Figure 1-14As shown, it also includes a sole body 2 for installing anti-slip claws for shoes. The sole body 2 has a working state receiving groove 21 for receiving the anti-slip claw body 1 when flipped to the working state, and a non-working receiving groove 22 for receiving the anti-slip claw body 1 when flipped to the non-working state. This utility model installs anti-slip claws on the bottom of the sole body 2. Specifically, the first connecting segment 11 and the second connecting segment 12 of the anti-slip claw body 1 face the sole body 2 and are connected to the sole body 2 through the first mounting component 111 and the second mounting component 121, respectively. The first connecting segment 11 and the first mounting component 111 are connected to each other in a rotatable pivotal manner through the first pivot 112, and the second connecting segment 12 and the second mounting component 121 are connected to each other in a rotatable pivotal manner through the second pivot 122. Moreover, the first pivot 112 and the second pivot 122 are coaxially arranged, so that the entire anti-slip claw body 1 can be rotated by the unified pivot formed by the first pivot 112 and the second pivot 122. This exposes the non-working surface of the anti-slip claw body 1 and puts it in a non-anti-slip use state for normal wear, or exposes the working surface of the anti-slip claw body 1 with anti-slip studs 3 and puts it in an anti-slip use state, so that it can be used safely and anti-slip on smooth outdoor surfaces such as ice and snow. To achieve practicality, durability, and enhanced anti-slip effects, multiple anti-slip studs 3 are constructed using wear-resistant reinforced alloys and other metal materials, and are integrally injection molded from high-strength resin. The stud head 311 is matched and embedded in the fixed stud hole, and the constricted hole wall 13 of the fixed stud hole securely positions the stud head 311, preventing the anti-slip studs 3 from falling off or shaking. Furthermore, the second radial protrusion 321 is secured to the outside of the constricted hole wall 13, preventing the anti-slip studs 3 from being pushed into the fixed stud hole or even pierced through the back seal 14 by the reaction force of stepping on the ground, thus preventing loss of anti-slip effect. The back seal 14 can also provide reinforced support on the back of the stud head 3112. In short, the multi-directional locking structure of the above structure provides all-round positioning and fixation of the anti-slip studs 3, ensuring durability. At the same time, the pointed structure of the exposed section 32 is more conducive to the anti-slip studs 3 embedding into hard, slippery surfaces such as ice, ensuring the anti-slip effect. Specifically, the non-working receiving groove 22 has a depth greater than the thickness of the anti-slip claw body 1. This structure ensures that the anti-slip claw body 1 does not protrude beyond the non-working receiving groove 22, allowing the sole body 2 to more easily contact the ground and function as a regular sole when the anti-slip claw is not in use, avoiding the discomfort of the anti-slip claw contacting the ground during normal wear. The working receiving groove 21 has a depth less than the thickness of the anti-slip claw body 1. This structure ensures that the anti-slip claw protrudes beyond the working receiving groove 21, allowing the anti-slip claw to more easily contact ice, snow, or other surfaces to provide anti-slip protection when in use. The anti-slip stud 3 can be made of high-strength, wear-resistant alloy materials such as manganese alloy or chromium alloy to ensure anti-slip performance when inserted into icy or snowy surfaces. The anti-slip claw body 1 can be made of high-toughness resin materials such as nylon or PC that can fix the anti-slip stud 3. The sole body 2 can be made of wear-resistant and anti-slip rubber material.

[0055] Specifically, the bottom of at least one of the working and non-working accommodating tanks 21 and 22 may have a water-guiding groove 23. The water-guiding groove 23 prevents water formed by rain, snow, and ice from accumulating in the working and non-working accommodating tanks 21 and 22, thus affecting normal use and anti-slip performance. Furthermore, the water-guiding groove 23 provides pressure relief space, preventing snow and ice debris from being compacted within the working and non-working accommodating tanks 21 and 22, which would severely affect operation and anti-slip performance. To ensure the water-guiding and pressure-relieving effects of the water-guiding groove 23, the bottom of both the working and non-working accommodating tanks 21 and 22 may have a water-guiding groove 23, and the water-guiding grooves 23 of both the working and non-working accommodating tanks 21 and 22 may extend along and connect with each other. Preferably, the bottom surface of the sole body 2 is provided with a glass sand anti-slip layer 20. On hard and smooth surfaces such as ice, the glass sand anti-slip layer 20 can effectively prevent slipping by cutting into the smooth surface for surface contact. Specifically, the glass sand anti-slip layer 20 is located between the first mounting groove 24 and the second mounting groove 25. This part is where the force on the sole of the shoe is concentrated, making it easier for the glass sand anti-slip layer 20 to play its role.

[0056] To ensure anti-slip performance, the sole body 2 includes a heel portion corresponding to the heel of the foot and a forefoot portion corresponding to the ball of the foot; anti-slip claws are installed on the heel and forefoot portions; the working state receiving groove 21 includes a heel working state receiving groove 21 located on the heel and facing the rear of the sole, and a forefoot working state receiving groove 21 located on the forefoot and facing the front of the sole; the non-working receiving groove 22 includes a heel non-working receiving groove 22 located on the heel and facing the front of the sole, and a forefoot non-working receiving groove 22 located on the forefoot and facing the rear of the sole. Anti-slip claws are provided at both the forefoot and heel areas of the sole body 2, and the front and rear anti-slip claws work together to provide all-around anti-slip performance for the entire sole. To facilitate the installation and fixation of the front and rear anti-slip claws, the specific structure can be such that the bottom of the sole body 2 has a first mounting groove 24 for a first connector to be inserted and a second mounting groove 25 for a second connector to be inserted. The first mounting groove 24 includes a first ball joint mounting groove located at the ball of the sole and a first heel joint mounting groove located at the heel of the sole. The second mounting groove 25 includes a second ball joint mounting groove located at the ball of the sole and a second heel joint mounting groove located at the heel of the sole. The first ball joint mounting groove and the second ball joint mounting groove are located between the ball joint working state receiving groove 21 and the ball joint non-working state receiving groove 22; the first heel joint mounting groove and the second heel joint mounting groove are located between the heel joint working state receiving groove 21 and the heel joint non-working state receiving groove 22. Further, the first ball joint mounting groove has a first ball joint locking neck for locking the first connector, and the second ball joint mounting groove has a second ball joint locking neck for locking the second connector; the first heel joint mounting groove has a first heel joint locking neck for locking the first connector, and the second heel joint mounting groove has a second heel joint locking neck for locking the second connector. This structure allows the sole body 2 to be firmly connected to the anti-slip claw, making it difficult to come loose. To achieve a secure snap-fit ​​between the sole body 2 and the claw positioning part 15, the sole body 2 has a bottom positioning part that engages with and snaps into position with the claw positioning part 15. Specifically, the bottom positioning part includes a palm positioning part located at the forefoot of the sole and a heel positioning part located at the heel of the sole; the palm positioning part includes a palm working positioning part 261 for positioning when the anti-slip claw is flipped to the working state, and a palm non-working positioning part 262 for positioning when the anti-slip claw is flipped to the non-working state; the heel positioning part includes a heel working positioning part 263 for positioning when the anti-slip claw is flipped to the working state, and a heel non-working positioning part 264 for positioning when the anti-slip claw is flipped to the non-working state. If the anti-slip claw is located on the sole of the main body 2 of the sole, when the anti-slip claw is flipped to the working state, the claw positioning part 15 protruding towards the pivot end and the working positioning part 261 of the sole are used to lock and position the anti-slip claw in the working state; when the anti-slip claw is flipped to the non-working state, the claw positioning part 15 and the non-working positioning part 262 of the sole are used to lock and position the anti-slip claw in the non-working state.If the anti-slip claw is located on the heel of the sole body 2, when the anti-slip claw is flipped to the working state, the claw positioning part 15 protruding towards the pivot end and the heel working positioning part 263 are locked together to keep the anti-slip claw in the working state; when the anti-slip claw is flipped to the non-working state, the claw positioning part 15 and the heel non-working positioning part 264 are locked together to keep the anti-slip claw in the non-working state. Further, the palm working positioning part 261 is a palm working positioning groove within the palm working state receiving groove 21, the palm non-working positioning part 262 is a palm non-working positioning groove within the palm non-working receiving groove 22, the heel working positioning part 263 is a heel working positioning groove within the heel working state receiving groove 21, and the heel non-working positioning part 264 is a heel non-working positioning groove within the heel non-working receiving groove 22. The sole has an outer working groove wall on the outer ring of the working groove 21, an inner working groove wall on the inner ring of the working groove 21, an outer non-working groove wall on the outer ring of the non-working groove 22, and an inner non-working groove wall on the inner ring of the non-working groove 22; the heel has an outer working groove wall on the outer ring of the heel working groove 21, and an inner working groove wall on the inner ring of the non-working groove 22. The inner ring has an inner ring working state groove wall, an outer ring non-working groove wall on the outer ring of the non-working groove 22, and an inner ring non-working groove wall on the inner ring of the non-working groove 22. The palm working positioning groove is located at the front end of the inner ring palm working state groove wall, the palm non-working positioning groove is located at the rear end of the inner ring palm non-working groove wall, the heel working positioning groove is located at the rear end of the inner ring heel working state groove wall, and the heel non-working positioning groove is located at the front end of the inner ring heel non-working groove wall. To facilitate user operation and adjustment of the anti-slip claw state, the outer ring palm working state groove wall, the inner ring palm working state groove wall, the outer ring heel working state groove wall, and the inner ring heel working state groove wall have prying notches 27 for inserting a pry bar and prying the anti-slip claw body 1. The user can use a small pry bar or other rod-like object to insert into the prying notches 27 to pry the anti-slip claw out of the working state groove 21 or the non-working groove 22. The crowbar can be a personal item that is pre-installed in the sole or a hole in the shoe, and the sole or shoe can have a hole for accommodating the crowbar.

[0057] To facilitate the storage of the anti-slip studs 3 and prevent them from damaging the soles of the shoes, the bottom of the non-working receiving groove 22 has multiple corresponding stud grooves 28 for accommodating each anti-slip stud 3. When the anti-slip claw is in a non-working state and is flipped into the non-working receiving groove 22, the stud grooves 28 can accommodate the anti-slip studs 3. Preferably, there is a gap between the groove wall of the stud groove 28 and the anti-slip stud 3 to cushion the impact of stepping and prevent the anti-slip stud 3 from colliding with the groove wall of the stud groove 28. Furthermore, the stud grooves 28 gradually widen from the bottom to the opening. This structure facilitates the drainage of ice, snow, water, etc., that enter the stud grooves 28, and also facilitates injection molding.

[0058] The specific structure can be such that the sole body 2 has a first limiting wall 291 that is limited to the outer ring of the first mounting component 111, and a second limiting wall 292 that is limited to the outer ring of the second mounting component 121. The first limiting wall 291 can limit and fix the first mounting component 111 to prevent shaking, and the second limiting wall 292 can limit and fix the second mounting component 121 to prevent shaking, thus preventing the first mounting component 111 or the second mounting component 121 from being twisted out of place by torsional forces during wearing. To ensure the limiting and fixing effect, the first limiting wall 291 further corresponds to limiting at least three sides of the first mounting component 111, and the second limiting wall 292 corresponds to limiting at least three sides of the second mounting component 121. Specifically, the first limiting wall 291 can be limited to the front, rear, and inner sides of the first mounting component 111, and the second limiting wall 292 can be limited to the front, rear, and inner sides of the second mounting component 121.
