Description

Technical Field

[0001] The present application relates to the field of sole structures, and in particular to an anti-slip sole. Background Art

[0002] Shoes are an important necessity in people's daily life. With the development of people's living standards and the footwear industry, the functional requirements for shoes are getting higher and higher. The performance requirements of the sole, an important component of shoes, are also getting higher and higher.

[0003] To improve the anti-slip properties of shoe soles, anti-slip bumps and drainage grooves are often provided on the bottom surface of the soles. The anti-slip bumps increase friction with the ground, while the drainage grooves facilitate the drainage of rainwater and reduce slipping. However, the drainage efficiency of existing soles is low, and the anti-slip properties need to be improved. Summary of the Invention

[0004] In order to improve the anti-slip effect, the present application provides an anti-slip sole.

[0005] The present application provides an anti-slip sole, which adopts the following technical solution:

[0006] A non-slip sole comprises a sole body, wherein the angle between the bottom surface of the sole body and the side surface of the sole body is greater than 90 degrees, the bottom surface of the sole body is provided with a plurality of anti-slip bodies arranged at intervals along the length direction of the sole body, the anti-slip bodies extend along the width direction of the sole body and extend to the side surface of the sole body, and drainage grooves are formed between adjacent anti-slip bodies; the anti-slip bodies comprise an anti-slip strip integrally formed on the bottom surface of the sole body and a plurality of anti-slip blocks, and the anti-slip blocks are arranged at intervals along the length direction of the anti-slip strip.

[0007] By adopting the above technical solution, firstly, by providing an anti-skid body with varying width to form a drainage groove with varying diameter, the water pressure in the drainage groove is changed, thereby accelerating the efficiency of water discharge and further improving the anti-skid property.

[0008] Secondly, the anti-skid body extends to the side of the sole body, that is, when rainwater is pressurized and discharged from the end of the drainage groove, the anti-skid body still maintains the convergence effect on the spraying rainwater, so as to reduce the occurrence of splashing caused by excessive scattering range after the rainwater is sprayed.

[0009] Optionally, there are three anti-slip blocks, and the anti-slip blocks at the ends of each anti-slip strip are arranged along the two long side contour lines of the sole body, and the anti-slip blocks in the middle of each anti-slip strip are arranged along the central axis of the sole body.

[0010] By adopting the above technical solution, the volume of the anti-slip block is larger than that of the anti-slip strip, so it can play a role in strengthening the structure of the sole body, and by limiting the position of the anti-slip block, the ability of the sole body to resist inward and outward rollover can be improved. At the same time, the three anti-slip blocks make the drainage groove have three diameter change points, and the diameter change points are the parts with smaller diameters of the drainage groove. Therefore, the rainwater in the drainage groove can be pressurized twice and have sufficient pressurized flow time, thereby comprehensively improving the drainage speed and drainage volume to improve the anti-slip effect.

[0011] Optionally, the sole main body includes a first sole and a second sole, wherein the second sole is fixed to the upper part of the first sole, and the anti-slip body is arranged on the bottom surface of the first sole; the anti-slip block is provided with two reinforcement strips symmetrically arranged with the anti-slip block as the center, the reinforcement strips are made of carbon fiber material, the reinforcement strips are inclined, and the reinforcement strips are arranged along the length direction of the anti-slip block, one side of the reinforcement strip is integrally formed with a plurality of force transmission thorns arranged at intervals along the length direction of the reinforcement strip, the other side of the reinforcement strip is integrally formed with a first bent portion, the force transmission thorns extend into the interior of the anti-slip block, and the force transmission thorns of the reinforcement strips on both sides of the anti-slip block are staggered, the outer convex arc surface of the first bent portion faces the notch of the drainage groove, and the first bent portion abuts against the bottom surface of the drainage groove.

[0012] By adopting the above technical solution, by setting up reinforcing strips and force-transmitting spikes made of carbon fiber material, and utilizing its high hardness and high strength characteristics to serve as the skeleton of the anti-slip block, the support of the anti-slip body is increased, so as to improve the structural stability of the sole body, thereby reducing the deformation and wear of the anti-slip body due to long-term stepping, thereby ensuring the stability of the anti-slip property.

[0013] Secondly, when the anti-slip block is subjected to pressure from the road surface, the pressure will be transmitted to the sole main structure near the anti-slip block through the force transmission thorns, the reinforcement strip, and the first bent portion in sequence, thereby reducing the pressure on the anti-slip block and improving the durability of the anti-slip block.

[0014] Thirdly, the staggered force-transmitting thorns can not only improve the connection strength between the reinforcing strip and the anti-sliding block, but also increase the freedom of the anti-sliding block to bend and deform along its own length, so as to take into account the bendability of the sole body.

[0015] Optionally, a connecting strip is provided in the drainage groove, and the connecting strip is made of carbon fiber. The connecting strip is arranged along the length direction of the drainage groove, and the connecting strip is fixedly connected to the first sole. The upper surface of the connecting strip fits with the bottom of the drainage groove, and both side edges of the connecting strip are integrally formed with a second curved portion, and the concave arc surface of the second curved portion faces the notch of the drainage groove, and the convex arc surface of the second curved portion is arranged tangent to the convex arc surface of the adjacent first curved portion.

[0016] By adopting the above technical solution, a connecting strip is provided, on which the second curved portion is tangentially abutted against the first curved portion of the reinforcing strip to limit the reinforcing strip, thereby reducing the occurrence of the reinforcing strip detaching from the anti-sliding block.

[0017] Furthermore, when the sole body is bent and deformed, the first curved portion and the second curved portion both move to corresponding positions. However, since the first curved portion and the second curved portion are tangentially abutted, while maintaining abutment, the first curved portion and the second curved portion elastically deform and avoid each other by utilizing the strong toughness of the carbon fiber material, so that the abutment point between the first curved portion and the second curved portion will change position along the abutment arc between the two, thereby ensuring that the forces between the reinforcing strip and the connecting strip are kept transmitted to each other, so that the reinforcing strip and the connecting strip form a support structure to improve the structural stability of the sole body, and the use of a separated abutment type can reduce the breakage of the carbon fiber caused by the integrated support structure, thereby improving the durability of the support structure.

[0018] Optionally, there are two connecting strips in the drainage groove and they are arranged along the length direction of the drainage groove. The middle part of the connecting strip is fixedly connected to the first sole by a rivet. The rivet is located between the two anti-slip strips. Both ends of the rivet have an end. The upper end abuts against the upper surface of the first sole, and the lower end abuts against the lower surface of the connecting strip.

[0019] By adopting the above technical solution, firstly, two connecting strips are provided. When the sole turns inward or outward, the two connecting strips can respectively play a supporting role, thereby effectively improving the stability of the sole; secondly, by using rivets for fixing, the installation connection between the connecting strip and the first sole can be achieved quickly and stably; thirdly, the rivets also provide the connecting strip with the freedom to rotate a certain small angle around the rivet axis, so that when the side-turning force of the sole is too large, the connecting strip can adaptively rotate a certain angle according to the force conditions of the sole, and convert the side-turning force to the sole part located on the bottom surface of the drainage groove, thereby reducing damage to the connecting strip and improving durability.

[0020] Optionally, the rivet is a hollow tubular structure, and the side wall of the rivet is penetrated by a plurality of through holes evenly arranged along its own circumference, and the through holes are extended along the axial direction of the rivet. The first sole is provided with a mounting hole for the rivet to pass through, and the hole wall of the mounting hole is provided with a tooth groove corresponding to the through hole. The inner cavity of the rivet is filled with silicone weather-resistant structural colloid.

[0021] By adopting the above technical solution, firstly, the silicone weather-resistant structural colloid has good waterproofness, elasticity and stability, and is filled into the inner cavity, through hole and tooth groove of the rivet, thereby greatly improving the sealing of the first sole; secondly, the part of the silicone weather-resistant structural colloid located in the through hole and tooth groove can play a role of elastic limitation on the rotational freedom of the rivet, thereby reducing the loosening and spinning phenomenon of the rivet; thirdly, the silicone weather-resistant structural colloid can also improve the connection strength between the rivet and the first sole, thereby reducing the occurrence of rivet detachment or vertical movement displacement.

[0022] Optionally, a plurality of deformation grooves are formed on the upper surface of the connecting strip, and the deformation grooves extend along the width direction of the connecting strip. The silicone weather-resistant structural colloid is filled in the deformation grooves and the gap between the connecting strip and the bottom surface of the drainage groove.

[0023] By adopting the above technical solution, the connection strength between the connecting strip and the bottom surface of the first sole can be improved. In addition, the silicone weather-resistant structural colloid has bonding toughness and can buffer the force applied to the connecting strip, thereby improving the comprehensive mechanical properties of the connecting strip and the stability of the first sole.

[0024] Optionally, the connecting strip is located in the arch portion of the first sole, the rivet is a hollow tubular structure, the inner cavity wall of the rivet is provided with an internal thread, the internal thread of the rivet is connected to a screw, the upper end of the screw is fixed with a support plate, and the support plate is located in the gap between the first sole and the second sole.

[0025] By adopting the above technical solution, multiple height-adjustable support plates can support the arch of the second sole to adapt to the different flat feet of different users.

[0026] Optionally, an air cavity is formed between the heel portion of the second sole, a sac-shaped elastomer is provided in the air cavity, an air channel extending along the length direction of the second sole is opened on the lower surface of the second sole, one end of the air channel is connected to the air cavity, and an air hole connected to the air channel is opened through the upper surface of the forefoot portion of the second sole.

[0027] By adopting the above technical solution, when the user walks, the heel touches the ground first. Therefore, the air cavity is squeezed first, so that the air in the air cavity is discharged from the air hole through the air channel to blow air between the user's toes, thereby dissipating the heat in the toe gap. When the heel leaves the ground, the sac-shaped elastomer recovers its deformation, the volume of the air cavity is restored, and negative pressure is formed. The air in the shoe flows back into the air cavity through the air hole, and this reciprocating process allows air to flow between the user's toes, thereby reducing the discomfort caused by heat accumulation.

[0028] Optionally, the support plate is located in the air duct, and there are four support plates located on the arch of the first sole. The support plate is a fan-shaped structure, and the center of the support plate is coaxially fixedly connected to the screw. When the outer arc surfaces of two adjacent support plates are tangent, the air duct is closed.

[0029] By adopting the above technical solution, firstly, the support area formed by the four support plates will change its position according to the different rotation angles of different support plates, thereby meeting the support needs of different parts of the user; secondly, according to the different rotation angles of two adjacent support plates, the distance between the outer arc surfaces of the two support plates will also be different, so that the diameter of the airway can be controlled to control the flow rate and flow rate of the air hole, thereby achieving good heat dissipation or maintaining the air pressure in the air cavity, so as to take into account both heat dissipation and the rebound effect of the heel.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. By setting up anti-skid bodies with varying widths to form variable diameter drainage grooves, the water pressure in the drainage grooves is changed, thereby accelerating the efficiency of water discharge and improving anti-skid performance;

[0032] 2. By setting up carbon fiber reinforcement strips and force-transmitting spikes, taking advantage of their high hardness and strength, they serve as the skeleton of the anti-slip member, thereby increasing the support of the anti-slip body and improving the structural stability of the sole body, thereby reducing the deformation and wear of the anti-slip body due to long-term pressure, thereby ensuring the stability of the anti-slip performance;

[0033] 3. By providing a reinforcing strip and a connecting strip, and utilizing the tangential contact between the first curved portion and the second curved portion, it is ensured that the forces between the reinforcing strip and the connecting strip are transmitted to each other, so that the reinforcing strip and the connecting strip form a durable support structure, thereby improving the structural stability of the sole body;

[0034] 4. By providing a sac-like elastic body and an air cavity, the air is squeezed when the user walks, so that the air flows between the user's toes, thereby reducing the discomfort caused by heat accumulation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0047] The following is combined with Figure 1-11 This application is described in further detail.

[0048] Example 1 of the present application discloses an anti-slip sole.

[0049] Reference Figure 1 and Figure 2 The anti-slip sole includes a sole body 10, which is made of ETPU material. The side of the sole body 10 is an outward convex arc surface, so that the angle between the bottom surface of the sole body 10 and the side surface of the sole body 10 is greater than 90 degrees.

[0050] like Figure 1As shown, the bottom surface of the sole body 10 is provided with multiple anti-skid bodies 20, and the anti-skid bodies 20 are arranged at intervals along the length direction of the sole body 10. The anti-skid bodies 20 extend along the width direction of the sole body 10. Drainage grooves 30 are formed between adjacent anti-skid bodies 20, and the anti-skid bodies 20 extend to the side of the sole body 10, that is, the drainage grooves 30 also extend to the side of the sole body 10.

[0051] The anti-slip body 20 includes an anti-slip strip 1 integrally formed on the bottom surface of the sole main body 10, and multiple anti-slip blocks 2 are integrally formed on the anti-slip strip 1. In this embodiment, there are three anti-slip blocks 2, and each anti-slip block 2 is arranged at intervals along the length direction of the anti-slip strip 1. The anti-slip blocks 2 located at the ends of each anti-slip strip 1 are respectively arranged along the two long side contour lines of the sole main body 10, and the anti-slip blocks 2 located in the middle of each anti-slip strip 1 are arranged along the central axis of the sole main body 10.

[0052] The width of the anti-slip block 2 is greater than the width of the anti-slip strip 1, so that the groove width of the drainage groove 30 located on the two opposite anti-slip blocks 2 is smaller, and the groove width of the drainage groove 30 located on the two opposite anti-slip strips 1 is larger, ultimately making the groove width of the drainage groove 30 along its own length direction large-small-large-small-large-small-large. In this embodiment, the anti-slip block 2 is elliptical, and the long axis of the elliptical anti-slip block 2 is set along the length of the anti-slip strip 1.

[0053] At the same time, the surfaces of the anti-slip strip 1 and the anti-slip block 2 are both protruded with a plurality of anti-slip bumps (not shown in the figure) to further enhance the anti-slip property.

[0054] The working principle of Example 1 is as follows: First, by providing anti-skid bodies 20 of varying width to form a variable-diameter drainage channel 30, the water pressure within the channel 30 is varied, thereby accelerating water drainage efficiency and improving anti-skid performance. Furthermore, the three anti-slip blocks 2 provide the channel 30 with three diameter-varying points, ensuring that rainwater in the channel 30 is pressurized twice and has sufficient time to flow, thereby improving both drainage speed and volume, and enhancing the anti-skid effect.

[0055] Thirdly, by utilizing the anti-slip block 2 to strengthen the structure of the sole body 10 and limiting the position of the anti-slip block 2 , the anti-inward and anti-outward turning capabilities of the sole body 10 can be effectively improved.

[0056] Example 2

[0057] The difference between Example 2 and Example 1 is that Figure 3 、 Figure 4As shown, the sole body 10 includes a first sole 101 and a second sole 102, wherein the first sole 101 is made of rubber, which has strong wear resistance, and the anti-slip body 20 is arranged on the bottom surface of the first sole 101, and the second sole 102 is made of ETPU, and the second sole 102 is fixed to the upper part of the first sole 101 by bonding.

[0058] The anti-sliding block 2 is provided with two reinforcing strips 3, which are located in the drainage groove 30. The two reinforcing strips 3 are symmetrically arranged with the anti-sliding block 2 as the center. The length direction of the reinforcing strips 3 is arranged along the long axis of the anti-sliding block 2. The reinforcing strips 3 are made of carbon fiber material, and the cross section of the reinforcing strips 3 is inclined.

[0059] A plurality of force-transmitting spikes 31 are integrally formed on one side of the reinforcing strip 3 close to the anti-sliding block 2. The force-transmitting spikes 31 are arranged at intervals along the length direction of the reinforcing strip 3. The force-transmitting spikes 31 extend into the interior of the anti-sliding block 2. In addition, the force-transmitting spikes 31 of the reinforcing strips 3 on both sides of the anti-sliding block 2 are staggered.

[0060] The force transmission spikes 31 and the anti-slip block 2 can be installed by pre-opening a hole in the anti-slip block 2 to allow the force transmission spikes 31 to pass through the hole, or by placing the reinforcing strip 3 with the force transmission spikes 31 into a mold, injection molding the first sole 101, and the injection-molded anti-slip block 2 wrapping the force transmission spikes 31 therein.

[0061] A first curved portion 32 is integrally formed on one side of the reinforcing strip 3 away from the anti-slip block 2, and the convex arc surface of the first curved portion 32 faces the groove opening of the drainage groove 30, and the first curved portion 32 abuts against the groove bottom surface of the drainage groove 30, and an adapter portion 21 is integrally formed on the bottom surface of the first sole 101, and the surface of the adapter portion 21 fits with the concave arc surface of the first curved portion 32.

[0062] When the anti-slip block 2 is subjected to road pressure, the pressure will be transmitted to the structure of the first sole 101 near the anti-slip block 2 through the force transmission thorns 31, the reinforcement strip 3, and the first bent portion 32 in sequence, thereby reducing the pressure on the anti-slip block 2 and improving the durability of the anti-slip block 2.

[0063] Secondly, the reinforcing strips 3 and the force-transmitting spikes 31 made of carbon fiber material have the characteristics of high hardness and high strength, and serve as the skeleton of the anti-slip block 2, thereby increasing the support of the anti-slip body 20, so as to improve the structural stability of the sole body 10, thereby reducing the deformation and wear of the anti-slip body 20 due to long-term stepping, thereby ensuring the stability of the anti-slip property.

[0064] Example 3

[0065] Example 3 makes the following settings based on Example 2: Figure 5As shown, two connecting strips 4 are further provided in the drainage groove 30. The connecting strips 4 are made of carbon fiber. The length direction of the connecting strip 4 is arranged along the length direction of the drainage groove 30. The two connecting strips 4 are arranged along the length direction of the drainage groove 30. The cross-section of the connecting strip 4 is V-shaped, and the upper surface of the connecting strip 4 fits with the bottom of the drainage groove 30. The arch portion of the first sole 101 is arranged corresponding to the arch portion of the foot. In this embodiment, the connecting strip 4 is arranged in the drainage groove 30 of the arch portion of the first sole 101. In other embodiments, the drainage groove 30 in each part can be provided with a connecting strip 4.

[0066] The connecting strip 4 is a structure that is wide in the middle and narrow at both ends. The middle part of the connecting strip 4 is named the connecting part 41, and the ends of the connecting strip 4 are named the abutting part 42. The connecting part 41 is located between two opposite anti-slip strips 1, and the abutting part 42 is located between two opposite anti-slip blocks 2.

[0067] like Figure 6 、 Figure 7 As shown, the two side edges of the connecting portion 41 respectively abut against the side walls of the anti-slip strip 1 on one side, and the connecting portion 41 is fixedly connected to the first sole 101. The specific fixing method is that the first sole 101 is vertically provided with a mounting hole 103, and the mounting hole 103 is located between the two relative anti-slip strips 1. The connecting portion 41 and the first sole 101 are vertically penetrated by a rivet 5, and the rivet 5 passes through the mounting hole 103. Both ends of the rivet 5 have an end 51, and the size of the end 51 is larger than the mounting hole 103. The upper end 51 abuts against the upper surface of the first sole 101, and the lower end 51 abuts against the lower surface of the connecting strip 4, thereby connecting the connecting strip 4 to the first sole 101. Since the bottom surface of the second sole 102 fits the top surface of the first sole 101, it covers the rivet 5 to reduce the external mud and water of the first sole 101 from entering the foot through the rivet 5.

[0068] In addition, the rivet 5 is hollow and tubular, and a plurality of through holes 52 are provided on the side wall of the rivet 5 along its own radial direction. The through holes 52 are long holes arranged along the axial direction of the rivet 5, and the through holes 52 are evenly arranged around the circumference; a plurality of tooth grooves 104 are provided on the hole wall of the mounting hole 103, and the tooth grooves 104 are arranged one-to-one corresponding to the through holes 52; a plurality of deformation grooves 411 are provided on the upper surface of the connecting portion 41, and the deformation grooves 411 are connected to the tooth grooves 104.

[0069] like Figure 5 、 Figure 8 As shown, both side edges of the abutment portion 42 are integrally formed with a second curved portion 43, the concave arc surface of the second curved portion 43 faces the notch of the drainage groove 30, and the convex arc surface of the second curved portion 43 is tangent to the convex arc surface of the adjacent first curved portion 32. This tangent abutment is utilized to limit the reinforcing strip 3, thereby reducing the occurrence of the reinforcing strip 3 detaching from the anti-sliding block 2.

[0070] After the rivet 5 is driven in, the lower end of the rivet 5 is sealed, and then the silicone weather-resistant structural adhesive is injected into the inner cavity of the rivet 5. At this time, the silicone weather-resistant structural adhesive will overflow into the tooth groove 104, the deformation groove 411, and the gap between the connecting strip 4 and the bottom surface of the drainage groove 30 through the through hole 52 to solidify and form a silicone weather-resistant structural colloid (not marked in the figure).

[0071] The silicone weather-resistant structural colloid has good waterproofness, elasticity and stability, and can greatly improve the sealing performance of the first sole 101. Secondly, the portion of the silicone weather-resistant structural colloid located in the through hole 52 and the tooth groove 104 can play a role in elastically limiting the rotational freedom of the rivet 5, thereby reducing the loosening and spinning phenomenon of the rivet 5.

[0072] The implementation principle of Example 3 is: when the sole body 10 undergoes bending deformation (bending along its own length direction), the first bending portion 32 and the second bending portion 43 both move to corresponding positions, but since the first bending portion 32 and the second bending portion 43 are tangentially abutted, while maintaining abutment, utilizing the strong toughness of the carbon fiber material, the first bending portion 32 and the second bending portion 43 elastically deform and avoid each other, so that the abutment point between the first bending portion 32 and the second bending portion 43 will change position along the abutment arc between the two, thereby ensuring that the acting force between the reinforcing strip 3 and the connecting strip 4 remains transmitted to each other, so that the reinforcing strip 3 and the connecting strip 4 form a support structure to improve the structural stability of the sole body 10.

[0073] When the sole is deformed sideways, the first curved portion 32 and the second curved portion 43 will also undergo elastic deformation to avoid each other, so that the contact point between the first curved portion 32 and the second curved portion 43 will move along the contact arc between the two (along the length direction of the connecting strip 4), thereby ensuring that the reinforcing strip 3 and the connecting strip 4 form a support structure to improve the structural stability of the sole body 10.

[0074] Secondly, the connecting strip 4 is connected to the first sole 101 through the rivet 5, and the rivet 5 allows the connecting strip 4 to elastically rotate around the axis of the rivet 5 at a certain small angle of freedom. Therefore, when the rollover force of the sole is too large, the connecting strip 4 can adaptively rotate to a certain angle according to the force conditions of the sole, and convert the rollover force to the sole part located on the bottom surface of the drainage groove 30, thereby reducing damage to the connecting strip 4 and improving durability.

[0075] Example 4

[0076] The difference between Example 4 and Example 3 is that Figure 9 、 Figure 10As shown, a groove is provided at the heel of the second sole 102, and the first sole 101 blocks the notch of the groove to form an air cavity 105. A sac-like elastomer 108 is provided in the air cavity 105. The sac of the sac-like elastomer 108 is made of rubber and is filled with gas. The sac-like elastomer 108 is used to make the air cavity 105 have elastic deformation recovery force.

[0077] An air channel 106 extending along the length direction of the second sole 102 is provided on the lower surface of the second sole 102, and one end of the air channel 106 is connected to the air cavity 105. An air hole 107 connected to the air channel 106 is provided on the upper surface of the forefoot portion of the second sole 102, so that the air hole 107 is connected to the air cavity 105. There are multiple air holes 107, and the openings of the air holes 107 are set toward the toe gap of the foot.

[0078] like Figure 10 、 Figure 11 As shown, in this embodiment, there are four connecting strips 4 located at the arch part of the first sole 101, the inner cavity wall of the rivet 5 is provided with an internal thread (not shown in the figure), the inner cavity thread of the rivet 5 is connected to a screw rod 7, one end of the screw rod 7 is fixed with a support piece 6, the support piece 6 is a fan-shaped structure, the center of the support piece 6 is coaxially fixed with the screw rod 7, the other end face of the screw rod 7 is provided with a cross pattern (not shown in the figure), the cross pattern is used for a cross screwdriver to rotate to drive the support piece 6 to change the angle and height.

[0079] When the user walks, the heel touches the ground first, squeezing the air cavity 105 first, so that the air in the air cavity 105 is discharged from the air hole 107 through the air channel 106 to blow air between the user's toes, thereby dissipating the heat in the toe gap. When the heel leaves the ground, the bladder-like elastomer 108 recovers its deformation, and the volume of the air cavity 105 is restored, forming a negative pressure. The air in the shoe flows back to the air cavity 105 through the air hole 107, and this reciprocating process allows the air to flow between the user's toes, thereby reducing the discomfort caused by heat accumulation.

[0080] The function of the support plate 6 is that the support plate 6 can support the arch of the second sole 102, so as to adapt to the flat feet of different users in different situations; secondly, according to the different rotation angles of the two adjacent support plates 6, the distance between the outer arc surfaces of the two support plates 6 is also different, so that the diameter of the air channel 106 can be controlled (when the outer arc surfaces of the two adjacent support plates 6 are tangent, the air channel 106 is closed) to control the flow and flow rate of the air hole 107, so as to achieve good heat dissipation or maintain the air pressure in the air cavity 105, so as to take into account both heat dissipation and the rebound effect of the heel.

[0081] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
