Description

Technical Field

[0001] The present invention belongs to the technical field of shoe soles, and particularly relates to an anti-slip structure, a shoe sole and its application. Background Art

[0002] As the core component in contact with the ground for the human body, the shoe sole is widely used in fields such as outdoor sports equipment, industrial protective shoes and boots, and special operation equipment, providing grip, stability and protection for users. In extreme environments such as mountaineering, cross-country running, and snow exploration, the anti-slip performance of the shoe sole is directly related to the safety of the athlete and the operation efficiency. In such outdoor scenarios, the shoe sole needs to cope with various complex terrains such as ice and snow, slippery rocks, and muddy mountain roads at the same time, which poses higher requirements for anti-slip technology.

[0003] When conducting snow exploration scenarios, although existing climbing shoes strengthen the grip on ice and snow terrain through designs such as steel nail implantation and serrated patterns, there are still technical defects. Although fixed steel nails can be briefly embedded in the ice surface, they will produce rigid collisions when contacting hard ground surfaces (such as exposed rocks and frozen soil), and cannot adapt to the unevenness of various terrains. This not only causes a strong sense of walking tremor, but also easily leads to foot fatigue after long-term use. In addition, for the situation where some steel nail components are damaged, since the steel nails are fixed to the shoe sole, the replacement is complex. In extreme environments, physical strength needs to be conserved to cope with the challenges of extreme environments, and it cannot be quickly disassembled and adjusted, resulting in a poor user experience.

[0004] For example, in the prior art, the publication number TW200608911A is also a shoe with anti-slip accessories, but it requires manual adjustment of the shoe sole's expansion and contraction to control the friction with the ground, which is extremely inconvenient. Therefore, it is particularly important to design a shoe sole with an anti-slip structure to solve the above problems. Summary of the Invention

[0005] (I) Technical Problems to be Solved

[0006] In order to solve the above problems of the prior art, the present invention provides an anti-slip structure. By setting an embedded replaceable shock-absorbing anti-slip device, it can cope with different sports scenarios, facilitate disassembly and replacement, improve anti-slip and shock-absorbing capabilities, and use elastic deformation to adapt to shock absorption, facilitating people's movement.

[0007] The present invention also provides a shoe sole. By setting an anti-slip structure with an embedded replaceable shock-absorbing anti-slip device, it can adaptively shock-absorb to the unevenness of different sports scenarios, facilitate disassembly and replacement, improve anti-slip and shock-absorbing capabilities, and is easy to process.

[0080] Figure 1 Schematic structural diagram of the anti-slip structure according to an embodiment of the present invention, as Figure 1 shown, the structure of the anti-slip structure according to the present invention will be described in detail.

[0081] Figure 2 Overall structural diagram of the embedded nail assembly according to an embodiment of the present invention, Figure 3 Partial cross-sectional view of the anti-slip structure according to an embodiment of the present invention, as Figure 2 and Figure 3 shown, the overall structure of the anti-slip structure according to an embodiment of the present invention will be described in detail.

[0082] Describe an anti-slip structure according to an embodiment of the present invention, which includes a body 2, and a detachable embedded replaceable shock-absorbing anti-slip device for shock absorption and anti-slip is provided on the body 2. The embedded replaceable shock-absorbing anti-slip device includes an embedded nail assembly 1. The embedded nail assembly 1 includes a guide member 11 and a fixed base 12 that are movably arranged up and down, and an anti-slip portion 13 provided between the guide member 11 and the fixed base 12. The guide member 11 is used to guide and engage the shock-absorbing anti-slip device, the fixed base 12 is used to prevent the shock-absorbing anti-slip device from slipping out, and the anti-slip portion 13 is used to anti-slip and grip the ground when contacting the ground;

[0083] Wherein, the body 2 includes a first surface for contacting the ground and a second surface attached to the midsole of the shoe sole. Among them, the embedded replaceable shock-absorbing anti-slip device is arranged on the first surface of the body 2;

[0084] Wherein, the first surface includes an anti-slip unit 21 that extends from the body 2 of the anti-slip structure towards the ground by a first height H1, which is used to provide a first anti-slip force. When the foot contacts the ground, the anti-slip unit 21 can contact the ground first, increasing the contact area with the ground and closely fitting the uneven structure of the ground, so that the friction force of the first surface of the anti-slip structure for contacting the ground is increased, preventing slipping;

[0085] Wherein, at least one anti-slip unit 21 includes an anti-slip block 211, and an engaging groove 212 is provided in the anti-slip block 211 for detachably installing the embedded nail assembly 1.

[0086] In order to improve the anti-slip force, in the state where the embedded nail assembly 1 is installed in the engaging groove 212, the nail assembly 1 extends from the body 2 of the anti-slip structure towards the ground by a second height H2, which is used to provide a second anti-slip force. When the foot contacts the ground, the nail assembly 1 contacts the ground first to provide a second anti-slip force, increasing the contact depth with the ground. The nail assembly 1 can penetrate the ground surface layer (such as snow layer, mud or ice surface, etc.) and directly contact the lower layer of the ground to provide a stronger anti-slip force. Secondly, the anti-slip unit 21 contacts the ground to provide a first anti-slip force, providing more contact area with the ground, double anti-slip, suitable for contacting hard ground surfaces (such as bare rocks, frozen soil) in some extreme environments, providing a reliable anti-slip effect.

[0087] Figure 5 It is an exploded cross-sectional view of the embedded nail assembly according to an embodiment of the present invention. As Figure 5 shown, the structure of the embedded nail assembly according to an embodiment of the present invention will be described in detail.

[0088] To improve the stability of anti-slip gripping, the guiding member 11 includes a first contact portion 111 and a first connecting portion 112 provided at the bottom of the first contact portion 111. A first accommodating groove 113 is formed in the first connecting portion 112. The fixed base 12 is provided at the bottom of the guiding member 11 and includes a base body 121 and a second accommodating groove 122 provided inside the base body 121. A positioning groove 123 is coaxially provided at the bottom of the second accommodating groove 122. A through hole 124 is provided on the bottom surface of the base body 121. Among them, the first connecting portion 112 is movably provided in the second accommodating groove 122, and the through hole 124 and the positioning groove 123 are axially communicated, so that the fixed base 12 forms a vertically communicating structure.

[0089] Figure 6 The exploded view of the embedded nail assembly according to the embodiment of the present invention is as Figure 6 shown, and the connection method of the embedded nail assembly according to the present invention will be described in detail.

[0090] To improve stability, a first limiting ring is provided on the outer wall of the first connecting portion 112, and a second limiting ring that is snap-fitted with the outer wall of the first connecting portion 112 is provided on the inner wall of the second accommodating groove 122. Threaded connection is stable and convenient, and can quickly perform replacement and disassembly operations, improving convenience.

[0091] Figure 7 The cross-sectional view of the fixed base of the embedded nail assembly according to the embodiment of the present invention is as Figure 7 shown, and the structure of the base body according to the embodiment of the present invention will be described in detail.

[0092] To fit the anti-slip portion 13, the diameter of the second accommodating groove 122 is larger than that of the positioning groove 123, and the diameter of the positioning groove 123 is larger than that of the through hole 124. The positioning groove 123 is provided to fit the anti-slip portion 13 to improve its stability and prevent loosening.

[0094] In order to improve stability, the anti-slip portion 13 includes an anti-slip nail 131, and the outer wall of the anti-slip nail 131 is radially extended to be provided with a limiting flange 133 that is adapted to the positioning groove 123, wherein the anti-slip nail 131 is fixedly embedded in the positioning groove 123 and one end thereof passes through the through hole 124, and the other end thereof extends into the first accommodating groove 113 and abuts against the top wall of the first accommodating groove 113. By providing the limiting flange 133 on the outer wall of the anti-slip nail 131 and adapting it to the positioning groove 123, the anti-slip nail 131 can be firmly embedded in the positioning groove 123 to avoid displacement or loosening due to external force during use, which not only enhances the overall stability of the anti-slip portion 13, but also effectively improves the service life.

[0095] Figure 2 FIG. 1 is a schematic diagram of the overall structure of an embedded nail assembly according to an embodiment of the present invention. Figure 2 As shown, the overall structure of the embedded nail assembly according to the embodiment of the present invention will be described in detail.

[0096] In order to facilitate the rapid assembly and positioning of the device, the first contact portion 111 is in the shape of a hemisphere. The arc shape of the hemisphere not only provides a guiding function to facilitate its clamping and assembly, but also reduces friction resistance during the assembly process to ensure precise alignment between components.

[0097] In order to prevent horizontal rotational movement, the seat body 121 is a polygonal prism structure that is equal in top and bottom, and is used to prevent horizontal rotational movement. The geometric characteristics of the polygonal prism can provide geometric constraints in the horizontal direction, effectively limiting the rotation or displacement of components on the horizontal plane, thereby ensuring the reliability of the device in a dynamic environment.

[0098] Figure 10 FIG. 4 is a cross-sectional view of an embedded nail assembly according to an embodiment of the present invention. Figure 10 As shown, the overall structure of the embedded nail assembly according to the embodiment of the present invention will be described in detail.

[0099] In order to prevent slipping, a part of the first connecting portion 112 is installed in the second accommodating groove 122, and the other part is exposed at the opening of the second accommodating groove 122, and together with the bottom surface of the first contact portion 111 and the top surface of the seat body 121, an annular limiting groove 114 is enclosed to prevent it from slipping out up and down. The limiting groove 114 forms a groove in the radial direction to limit its axial movement, prevent it from vibrating and slipping out during movement, and improve stability.

[0100] In order to adapt to the needs of different scenarios, the anti-slip part 13 is made of any one of steel, plastic, and carbon fiber, which can meet the needs of different application scenarios. Combining the advantages of various materials, the applicability and reliability of the device are improved, and flexible selection space is provided for users.

[0102] To improve the stability of the anti-slip structure, the fitting groove 212 is a multi-layer structure. A limiting block 215 adapted to the limiting groove 114 is provided between the upper and lower layers of the fitting groove 212. The limiting block 215 divides the fitting groove 212 into an upper layer groove 2121 and a lower layer groove 2122 arranged up and down. The shapes of its upper and lower layers are respectively adapted to the first connecting portion 112 and the seat body 121, providing double-layer fixed protection in the longitudinal and transverse directions, effectively improving the stability during movement, preventing slippage, enabling the anti-slip structure to maintain good grip under various ground conditions, such as wet and greasy surfaces, effectively preventing slipping, enhancing the safety and comfort of the user. At the same time, in case the nail assembly 1 is damaged, it can be quickly removed from the fitting groove 212.

[0103] To improve the axial stability, when the nail assembly 1 is engaged with the fitting groove 212, its first contact portion 111 is guided into the upper layer groove 2121, and the limiting block 215 and the limiting groove 114 are engaged with each other to limit the axial movement of the nail assembly 1 and prevent slippage during movement.

[0104] To improve the horizontal stability, when the nail assembly 1 is engaged with the fitting groove 212, its seat body 121 is cooperatively engaged with the lower layer groove 2122. The shape of the lower layer groove 2122 is a polygonal groove adapted to the seat body 121, forming a geometric constraint on the nail assembly 1 to limit the horizontal rotational movement of the nail assembly 1 and enhance the anti-detachment effect.

[0105] Figure 12 This is a cross-sectional view of the fitting groove according to an embodiment of the present invention. As Figure 10 shown, the structure of the convex portion of the anti-slip structure according to an embodiment of the present invention will be described in detail.

[0106] To provide a space for accommodating the nail assembly 1, the bottom wall of the fitting groove 212 protrudes upward to form a spherical convex portion 213 on the top surface of the body 2, which is used to provide a space for accommodating the nail assembly 1. The depth of this space is related to the height of the nail assembly 1.

[0108] To facilitate disassembly, replacement, and removal, a prying groove 214 is provided by extending the inner wall on any side of the fitting groove 212 outward, which is used for the quick disassembly and replacement of the nail assembly 1. When the nail assembly 1 is damaged, the nail assembly 1 can be quickly removed and replaced through the prying groove 214, improving the convenience.

The loading and unloading auxiliary tool 3 includes a prying part 31 and a holding part 32. A positioning hole 33 for auxiliary installation is provided at the bottom of the holding part 32. During disassembly, hold the holding part 32 by hand, align the prying part 31 with the prying groove 214, vertically insert it into the groove, and then pull it out vertically with force to remove the nail assembly 1. During installation, the nail assembly 1 can be directly picked up by hand, align one end of the guiding member 11 with the fitting groove 212, and press it vertically to complete the installation. The positioning hole 33 for auxiliary installation can also be used. First, embed the part of the anti-slip nail 131 at the bottom of the nail assembly 1 that exposes the through hole 124 into the positioning hole 33, and then align it with the fitting groove 212 and press it vertically into it to complete the replacement. Or first initially engage the nail assembly 1 and place it into the fitting groove 212, and then align the positioning hole 33 of the loading and unloading auxiliary tool 3 with the anti-slip nail 131 and press it vertically. Multiple disassembly, replacement, and installation methods are provided to improve the convenience of replacement, and it can cope with the situation of component damage in extreme weather for rapid replacement.

[0111] Figure 1 The structure schematic diagram of the anti-slip structure according to an embodiment of the present invention is as follows. As Figure 1 shown, the shock absorption and anti-slip effect of the anti-slip structure according to an embodiment of the present invention will be described in detail.

[0112] To improve comfort and shock absorption effect, the anti-slip units 21 are respectively distributed in a fractal geometry on the front and rear palms of the body 2, dispersing the sole pressure to improve comfort. The anti-slip units 21 distributed in a fractal geometry can ensure that the pressure in each area of the sole is evenly distributed, thereby reducing the situation of excessive local pressure and improving the wearing comfort. At the same time, when the foot contacts the ground, it can fully absorb and disperse the impact force, enabling each anti-slip unit 21 to independently buffer the impact force, thereby reducing the vibration received by the foot and providing a better shock absorption effect.

[0113] To enhance the anti-slip effect, a number of anti-slip patterns 22 for enhancing anti-slip and grip are further provided at the bottom of the body 2, fully considering the usage requirements under different ground conditions, and further increasing the contact area between the anti-slip structure and the ground through the additionally provided anti-slip patterns 22.

[0114] To make the nail component firmly fitted on the anti-slip structure, the anti-slip structure is prepared with rare-earth cis-butadiene rubber and nitrile rubber as the main body. Rare-earth cis-butadiene rubber has extremely high elasticity and crystallization speed, good molecular chain flexibility, outstanding wear resistance and low wear amount, and is especially suitable for the high-frequency friction scenario where the sole contacts the ground for a long time. Nitrile rubber has relatively high tear strength and tensile strength, which can enhance the anti-destruction ability of the sole edge and bending parts and extend the service life. The two complement each other in performance, doubling the tear strength, tensile strength, elongation at break and wear resistance of the anti-slip structure. Among them, the performance of the anti-slip structure is as follows:

[0115] Tear strength > 8 kN / m

[0116] Tensile strength > 180 kg / cm²

[0117] Elongation at break > 600%

[0118] Wear resistance DIN < 90 mm³.

[0119] Example 2

[0120] For the sake of simplicity of description, the parts that are the same as those in Example 1 will not be described again. Now, the structure different from that of Example 1 of the present invention will be mainly described. The difference between Example 2 and Example 1 lies in the setting of the adaptive shock absorption of the anti-slip structure.

[0121] Figure 4 It is a partial cross-sectional view of the anti-slip structure according to another embodiment of the present invention. As Figure 4 shown, the shock absorption and anti-slip effect according to another embodiment of the present invention will be described in detail.

[0122] Figure 10 It is an exploded cross-sectional view of the embedded nail component according to another embodiment of the present invention. Figure 11 It is a combined cross-sectional view of the embedded nail component according to another embodiment of the present invention. As Figure 10 and Figure 11 shown, the combined structure of the embedded nail component according to another embodiment of the present invention will be described in detail.

[0123] To improve the anti-slip force, the body 2 includes a first surface for contacting the ground and a second surface attached to the midsole of the sole. Among them, the embedded replaceable shock absorption and anti-slip device is arranged on the first surface of the body 2;

[0124] Among them, in a state where the embedded nail assembly 1 is installed in the fitting groove 212, the nail assembly 1 extends from the body 2 of the anti-slip structure towards the ground to a height between the first height H1 and the second height H2, for providing an adaptive second anti-slip force. When the foot contacts the ground, the nail assembly 1 first contacts the ground to provide the second anti-slip force. When the nail assembly 1 contacts various uneven ground surfaces (such as snow layer, dirt road, rocky dirt road or ice surface, etc.), the retractable anti-slip part 13 provided inside the nail assembly 1 can adapt to the uneven conditions of different ground surfaces to provide a stronger anti-slip force. Secondly, the anti-slip unit 21 contacts the ground to provide the first anti-slip force, providing a larger contact area with the ground, with double anti-slip, applicable to contacting uneven ground surfaces (such as snow layer, dirt road, rocky dirt road) in some extreme environments, providing a reliable anti-slip effect.

[0125] In order to adapt to the uneven conditions of various terrains, the anti-slip part 13 includes an anti-slip nail 131. The outer wall of the anti-slip nail 131 extends radially to be provided with a limiting flange 133 adapted to the positioning groove 123. The anti-slip part 13 further includes a spring 132. One end of the spring 132 is embedded in the first accommodation groove 113, and the other end is sleeved on the anti-slip nail 131 and abuts against the top surface of the limiting flange 133. The anti-slip nail 131 is embedded in the positioning groove 123 and one end penetrates through the through hole 124, and the other end is telescopically arranged in the second accommodation groove 122 through the spring 132. Through the elastic deformation of the spring 132, the anti-slip nail 131 realizes the adaptive feedback to different terrain changes and the rise and fall of the center of gravity of the sole.

[0126] For adaptive shock absorption, in the walking process state, when the anti-slip structure contacts the ground, the spring 132 of the nail assembly 1 undergoes adaptive elastic deformation for the change of the center of gravity during walking to provide a height between the first height H1 and the second height H2. When walking on (such as snow layer, dirt road, rocky dirt road), the center of gravity of the sole first gathers at the rear sole position. At this time, the nail assembly 1 located at the rear sole first contacts the ground. Due to the action of pressure, the anti-slip nail 131 undergoes elastic deformation through the spring 132 and retracts into the second accommodation groove 122. When the center of gravity of the sole transitions to the front sole, the nail assembly 1 at the front sole responds to the pressure, and the anti-slip nail 131 undergoes elastic deformation through the spring 132 and retracts into the second accommodation groove 122;

[0127] During this process, due to different unevenness of the ground, for any anti-slip nail 131 of the nail assembly 1 where the ground protrudes, the elastic deformation of its spring 132 is relatively large, and the retraction amount of the spring 132 is also relatively large, thereby providing a height H3 between the first height H1 and the second height H2; for any anti-slip nail 131 of another arbitrary nail assembly 1 where the ground is recessed, the elastic deformation of its spring 132 is relatively small, and the retraction amount of the spring 132 is also relatively small, thereby providing a height H4 between the first height H1 and the second height H2. At this time, the adaptive situation of any two nail assemblies 1 on the sole to the ground is manifested as the heights H3 and H4 (H4 > H3) between the first height H1 and the second height H2, thereby completing the adaptation to different unevenness of the ground (when walking on any different uneven ground, any nail assembly 1 will adapt to the ground through the spring 132 and provide a height Hn between the first height H1 and the second height H2, and Hn satisfies H1 ≤ Hn ≤ H1 + H2);

[0128] Dynamically adjust the shock absorption effect according to different walking states (such as landing on the heel first or the forefoot first), reduce the direct transmission of the impact force to the foot, the spring 132 continuously makes elastic deformation in response to the change of the center of gravity, effectively buffers the impact force of the ground on the sole of the foot during walking, greatly reduces the burden on joints such as the knees and ankles during walking, and can also be adjusted in real time according to the change of the center of gravity on complex terrains such as snow layers, dirt roads, and rocky dirt roads to prevent slipping, thereby improving the comfort and stability of walking. Whether it is starting, accelerating, decelerating or turning during the movement process, it can provide reliable anti-slip protection.

[0129]

Sole according to an embodiment of the present invention

[0130] Embodiment 1

[0131] Figure 15 is a side view of the sole according to an embodiment of the present invention, Figure 16 is a top view of the midsole according to an embodiment of the present invention, as Figure 15 shown in Figure 16 will be described in detail the midsole structure according to an embodiment of the present invention.

[0132] As another aspect of the present invention, a sole is provided, further comprising a midsole 4, the midsole 4 having a first surface for contacting the instep and a second surface for contacting the anti-slip structure, wherein the second surface contacts the anti-slip structure as described in any one of the above, and wherein the second surface of the midsole 4 has at least one groove 411 adapted to the protrusion 213 for receiving the protrusion 213.

[0133] Figure 17 is a top view of the midsole according to an embodiment of the present invention, as Figure 17As shown, the groove structure according to an embodiment of the present invention will be described in detail.

[0134] To provide sufficient space, the groove 411 is used to provide a space for accommodating the protruding portion 213. The depth of this space is positively correlated with the height of the protruding portion 213 of the embedded nail assembly 1. When the height of the embedded nail assembly 1 is higher, the protruding height of the protruding portion 213 is higher, and the depth of the groove 411 is correspondingly deeper. At the same time, the cooperation between the groove 411 and the protruding portion 213 can increase the friction force of the contact surface, ensuring that the protruding portion 213 can be firmly embedded in the groove 411, thereby forming a greater frictional resistance between the contact surfaces and preventing sliding.

[0135] To improve the durability of the sole, the main body 2 and the midsole 4 are bonded together by one of gluing, hot melting, or sewing, which can ensure the bonding strength and stability between the main body 2 and the midsole 4, while enhancing the durability and production efficiency of the shoes.

[0136] Figure 9 The structural schematic diagram of the anti-slip structure according to an embodiment of the present invention is as Figure 9 As shown, the overall structure of the anti-slip structure according to an embodiment of the present invention will be described in detail.

[0137] To make the sole evenly distribute the force, the embedded nail assembly 1 is arranged in the anti-slip unit 21 in a fractal geometric arrangement centered on at least two nail assemblies 1 in the front sole of the shoe, so as to provide the driving force for greater grip required by the sole in the front sole area during movement (such as walking on muddy roads, mountain climbing, walking on ice). The embedded nail assembly 1 is arranged in the anti-slip unit 21 in a fractal geometric arrangement centered on at least one nail assembly 1 in the rear sole of the shoe, so as to provide the stability required by the sole in the rear sole area during movement (such as walking on muddy roads, mountain climbing, walking on ice), to disperse the impact force, and at the same time conform to the force distribution characteristics during human movement, so that the sole can maintain good grip and stability in various sports scenarios.

[0138] To improve production efficiency, the main body 2, the midsole 4, and the nail assembly 1 are processed in a layered manner. The main body 2 and the midsole 4 can be processed first, and then the nail assembly 1 and the main body 2 are processed and assembled. The processing during production is convenient and fast, and each component can be processed with high precision separately, avoiding losses caused by overall processing, thereby significantly improving the product yield, further reducing material waste, and achieving a decrease in production costs.

Usage method of the sole with the anti-slip structure according to the embodiment of the present invention

[0148] Usage method A of the sole with the anti-slip structure

[0149] When used on ice, by installing the nail assembly 1 on the outsole of the shoe sole, a strong anti-slip force can be obtained even on ice. Specifically, the anti-slip nails 131 of the nail assembly 1 first come into contact with the ground to provide a second anti-slip force, increasing the contact area with the ice surface. The nail assembly 1 can penetrate the ice surface and contact the lower layer of the ice surface to provide a stronger anti-slip force. Secondly, the anti-slip unit 21 comes into contact with the ice surface to provide a first anti-slip force, providing more contact area with the ground, achieving double anti-slip. By setting the spring 132, it can adapt to ice surfaces with different unevenness to adapt to the ice surface, effectively improving the anti-slip effect on ice.

[0150] Usage mode B of the shoe sole with anti-slip structure

[0151] When used on mountain stone dirt roads, by installing the nail assembly 1 on the outsole of the shoe sole, a strong anti-slip force can be obtained even on mountain stone dirt roads. Specifically, the anti-slip nails 131 of the nail assembly 1 first come into contact with the ground to provide a second anti-slip force, increasing the contact area with the mountain stone dirt road to provide a stronger anti-slip force. Secondly, the anti-slip unit 21 comes into contact with the mountain stone dirt road to provide a first anti-slip force, providing more contact area with the ground, achieving double anti-slip. By setting the spring 132, it can adapt to different uneven rocks to adapt to the mountain stone dirt road, effectively improving the anti-slip effect on mountain stone dirt roads.

[0152] When walking or exercising on various uneven bumpy roads, any nail assembly 1 will adapt to the ground through the spring 132. The spring 132 continuously makes elastic deformation in response to the change of the center of gravity, providing a height Hn between the first height H1 and the second height H2, where Hn satisfies H1≤Hn≤H1 + H2. This effectively buffers the impact force of the ground on the sole of the foot when walking, and adjusts in real time according to the change of the center of gravity and the unevenness of the ground, providing a strong anti-slip force and reliable sports guarantee.
