Description

Technical Field

[0001] The invention relates to the technical field of soles, and in particular to a sole high-resilience structure and a sole. Background Art

[0002] With the development of social economy and the continuous improvement of people's material level, more and more people pay attention to health and participate more in sports and fitness in daily life. In particular, during running and other sports, due to the effect of inertia, when the sole of the athlete's shoe touches the ground, the sole will be subjected to the downward pressure exerted by the body's own gravity on the sole, and the anti-impact force exerted by the bottom surface (generally equivalent to 3 to 5 times the body weight), which can easily cause certain damage to the athlete's knee joints and / or ankle joints and other human structures. Therefore, shoes are foot products that protect the legs and feet from injury, and the rebound and shock-absorbing function of shoes is very important and necessary.

[0003] Many shoes with rebound and shock-absorbing functions on the market are generally improved in the material or structure of the soles, such as using foamed thermoplastic polyurethane materials on the soles, and designing air columns, shock-absorbing pads and other structures on the soles. However, the current rebound and shock-absorbing soles often have a large hysteresis in the face of more intense sports, which cannot meet the needs of users. Summary of the invention

[0004] The purpose of the present invention is to overcome the above-mentioned defects or problems existing in the background technology and to provide a high-rebound sole structure and a sole, which have the advantages of rapid rebound and excellent shock-absorbing performance.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] Technical solution 1: A high-rebound structure of a sole, comprising: a support component, which has a plurality of support layers arranged in the up-down direction, and is provided with a rebound layer that extends continuously and obliquely from top to bottom toward the circumferential side, the rebound layer is arched and isolates the support layers on its upper and lower sides; and an outer covering layer that closes the outer side of the support component; in the support component, for each of the support layers, mutually perpendicular arrangement directions and channel directions are defined, each of the support layers is provided with a plurality of support channels arranged in sequence along the arrangement direction, and each of the support channels located in the same support layer extends along the channel direction; adjacent support layers are connected to each other, and their corresponding arrangement directions are perpendicular to each other, and the channel directions are also perpendicular to each other.

[0007] Technical solution 2 based on technical solution 1: the top of the resilience layer is closed to separate the support assembly into an upper support portion located on its upper side and a lower support portion located on its lower side.

[0008] Technical solution three based on technical solution two: the top of the resilience layer is connected to the top wall of the outer covering layer.

[0009] Technical solution 4 based on technical solution 3: the bottom edge of the resilience layer is connected to the bottom wall or side wall of the outer covering layer.

[0010] Technical solution 5 based on any one of technical solutions 1 to 4: in each supporting layer of the supporting assembly, the supporting channel is formed by two opposite side walls arranged along the arrangement direction corresponding to the supporting layer; the side walls are periodically arranged with a first curved segment and a second curved segment connected end to end along the channel direction corresponding to the supporting layer in which they are located, and the bending directions of the first curved segment and the second curved segment are opposite; between two adjacent side walls in the same supporting layer, the positions of their respective first curved segments are staggered, and the positions of their respective second curved segments are also staggered.

[0011] Technical solution six based on technical solution five: in the same supporting layer, the adjacent side walls have a tendency to lean closer to each other as they are closer to the junction of the adjacent supporting layers; and at the junction of adjacent supporting layers, in the same supporting layer, the starting point of the first curved section of the side wall is connected to the end point of the first curved section of the other adjacent side wall that is staggered therewith, and the starting point of the second curved section of the side wall is connected to the end point of the second curved section of the other adjacent side wall that is staggered therewith, so that the support channels in the adjacent supporting layers are connected.

[0012] Technical solution seven based on technical solution six: the starting points and end points of the first curved section and the second curved section in the side wall are inclined along the extension direction of the corresponding support channel, and the corresponding inclination directions of the first curved section and the second curved section in the same side wall are the same, and the corresponding inclination directions in adjacent side walls are opposite.

[0013] Technical solution eight based on technical solution seven: the closer the side wall is to the junction of adjacent support layers, the greater its curvature.

[0014] In addition, the present invention also provides technical solution nine: a sole, which adopts the high-rebound structure of the sole as described in any one of technical solutions one to eight.

[0015] Technical solution ten based on technical solution nine: the high-resilience structure of the sole is applied to the heel of the sole.

[0016] It can be seen from the above description of the present invention that, compared with the prior art, the present invention has the following beneficial effects:

[0017] Technical solution 1 provides a high-rebound structure of a sole, which includes a support component and an outer covering layer, wherein the support component is provided with a support layer and a rebound layer, and the outer covering layer seals the outer side of the support component, so that the support component forms a seal; the support layer in the support component is provided with a support channel, the support channel can accommodate air, and the channel directions of the support channels of adjacent support layers are perpendicular to each other, and the adjacent support layers are interconnected; when the support component is subjected to downward pressure, the support component will be squeezed as a whole, so that the air in the support channel is compressed, and when the pressure is removed, the air will restore its original volume, and in this process, the compression and recovery of the air will play a certain shock-absorbing role;

[0018] At the same time, the adjacent support layers in the vertical direction support each other, and because the support channels of the adjacent support layers are interlaced, when the support assembly is squeezed, the force received will be quickly and evenly dispersed throughout the entire support assembly, thereby providing a better shock-absorbing effect through the entire support assembly;

[0019] In addition, a rebound layer is provided in the support component, and the rebound layer is continuously inclined toward the circumference from top to bottom to form an arched structure, and the rebound layer is arranged between the support layers, thereby isolating the support layers on the upper and lower sides of the rebound layer; when the support component is subjected to force, due to the arched shape characteristics of the rebound layer, the rebound layer will be subjected to force through the support layer and open to the circumference, at this time the rebound layer will accumulate elastic potential energy, and when the force is removed, the rebound layer will quickly restore the deformation, thereby making the rebound speed of the high-rebound structure of the sole faster; and, the upper surface of the rebound layer will receive the force applied by the support layer above it, and the rebound layer will transfer the force to the support layer below it, which is equivalent to quickly and evenly dispersing the force applied to the support component to the entire support layer component through the rebound layer, thereby providing better rebound and shock-absorbing effects through the entire support component; at the same time, the rebound layer will also play a role in pulling the support layer in the horizontal direction, thereby improving the supporting performance of the support layer and better absorbing impact energy.

[0020] In technical solution two, the top of the rebound layer is closed, thereby separating the support assembly into an upper support part and a lower support part. In this process, since the rebound layer divides the entire support assembly into two isolated parts, the upper support part and the lower support part can independently compress and restore the air inside, which is equivalent to dividing the support assembly into two smaller spaces to form a chamber, making the compression and recovery of the air faster, and the overall rebound rate of the high-rebound structure of the sole is also faster, and the rebound and shock-absorbing effects are better.

[0021] In technical solution three, the top of the rebound layer is connected to the top wall of the outer covering layer. When the top wall of the outer covering layer receives external force, the force can be directly transferred to the rebound layer, and then transferred to the lower support part through the rebound layer. At the same time, the upper support part will also receive this force, thereby forming a rapid transmission of force, thereby improving the overall rebound and shock-absorbing performance of the high-rebound structure of the sole.

[0022] In technical solution four, the bottom edge of the rebound layer is connected to the bottom wall or side wall of the outer covering layer, and the boundary of the rebound layer is limited by the outer covering layer to prevent the rebound layer from excessive outward deformation. At the same time, the force of the top wall of the outer covering layer can be transferred to the side wall or bottom wall of the outer covering layer through the rebound layer, thereby improving the overall support performance of the high rebound structure of the sole.

[0023] In technical solution five, a support channel is formed by the cooperation of the side walls, and a first curved section and a second curved section are provided on the side walls. Compared with the straight side walls, the curved side walls have a larger equivalent support area in the arrangement direction. When subjected to downward pressure, the side walls themselves can form a certain support, which can then be fed back to the entire support assembly, thereby improving the shock-absorbing effect of the sole rebound boosting structure.

[0024] In technical solution six, in the same supporting layer, adjacent side walls have a tendency to lean closer, and there are connected parts between adjacent side walls. The mutually leaning structure makes the force transmission faster and can make the supporting performance of the side walls better. The adjacent side walls are connected, which can make the connecting parts between adjacent supporting layers more stable and increase the equivalent contact area of ​​the connecting parts, thereby improving the supporting performance and thus improving the overall shock absorbing effect.

[0025] In technical solution seven, the first curved section and the second curved section are inclined, which can make it easier for adjacent side walls to be connected as a whole, and the connecting positions are staggered, reducing the impact of excessive stress concentration, thereby improving the overall shock-absorbing effect.

[0026] In technical solution eight, the curvature of the side wall closer to the support layer is increased, so that the connection between adjacent side walls can be smoother, sudden changes in the structure can be avoided, and the resilience of the support assembly can be enhanced.

[0027] Technical solution nine provides a sole that adopts the above-mentioned high-rebound structure of the sole, has a faster rebound rate and better shock-absorbing and supporting performance.

[0028] In technical solution ten, the high-rebound structure of the sole is applied to the heel of the sole. When a user jumps and lands wearing shoes with the sole, the heel with the high-rebound structure can better absorb impact energy and provide quick rebound. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] In the claims, description and drawings of the present invention, if the terms "include", "have" and their variations are used, they are intended to mean "including but not limited to".

[0044] The embodiment of the present invention relates to a high-resilience structure of a sole, which can be applied to a sole and used as a midsole of the sole. This embodiment is mainly described with the high-resilience structure of the sole as the main body.

[0045] Reference Figure 1 The high-rebound structure of the sole involved in this embodiment includes a support component 10 and an outer covering layer 20, wherein the support component 10 is arranged with a plurality of support layers in the up-down direction, and is provided with a rebound layer 11 which extends continuously and obliquely from top to bottom toward the circumferential side, the rebound layer 11 is arched and isolates the support layers above and below it; the outer covering layer 20 closes the outer side of the support layer component.

[0046] In this embodiment, the high-rebound structure of the sole is prepared by 3D printing, and the material used can be thermoplastic polyurethane elastomer, and the thermoplastic polyurethane elastomer material can be selected from commercially available products, such as Detron AU brand polyurethane material, Covestro UT-AU brand polyurethane material and Lubrizol BF- brand polyurethane material. Alternatively, the material used can also be nylon, and the material brand can be selected according to actual needs. It should be understood that in this embodiment, when the sole rebound boosting structure is made of different materials, its shock absorbing performance will inevitably be different, but this difference will not affect the sole rebound boosting structure to achieve its function.

[0047] Furthermore, the materials used for the support assembly 10 and the outer covering layer 20 can be the same or different, and the materials used for the outer covering layer 20 at different positions can also be different. For example, the top wall of the outer covering layer 20 can be made of a material with higher elasticity, while the bottom wall of the outer covering layer 20 can be made of a material with higher hardness; at the same time, the material of the support assembly 10 can also be different from that of the outer covering layer 20, which will not affect the functional realization of the sole rebound boosting structure. However, it should be noted that the outer covering layer 20 should be an airtight material, and when it covers the upper, lower and surrounding sides of the support assembly 10, it can cooperate with the support assembly 10 to form a closed air chamber.

[0048] The support assembly 10 has several support layers arranged in the up-down direction. The uppermost and lowermost support layers are both enclosed by the outer covering layer 20. The outer covering layer 20 also encloses the surroundings of the support assembly. For each support layer, mutually perpendicular arrangement directions and channel directions are defined. Each support layer is provided with several support channels 12 arranged in sequence along the arrangement direction. Each support channel 12 located in the same support layer extends along the channel direction. Adjacent support layers are interconnected, and their corresponding arrangement directions are mutually perpendicular, and the channel directions are also mutually perpendicular. In addition, referring to Figure 2 and Figure 3 The resilience layer 11 in the support assembly 10 separates each support layer in the support assembly 10 in the up-down direction into two parts. Since the resilience layer 11 is in a shape that continuously extends from top to bottom toward the circumferential side, support layers at different heights are separated at different positions in the radial direction, and support layers belonging to the same layer are also separated. Therefore, although the resilience layer 11 separates the support layers belonging to the same layer into different up-down parts, the two parts still belong to the same support layer.

[0049] Firstly, the structure of the support layer in the high-resilience structure of the sole according to the embodiment of the present invention is described in detail below.

[0050] In each supporting layer of the supporting assembly 10, the supporting channel 12 is formed by two opposite side walls 13 arranged along the arrangement direction corresponding to the supporting layer; the side walls 13 are periodically arranged with first curved segments 14 and second curved segments 15 connected end to end along the channel direction corresponding to the supporting layer where they are located, and the bending directions of the first curved segments 14 and the second curved segments 15 are opposite; between two adjacent side walls 13 in the same supporting layer, the positions of the respective first curved segments 14 are staggered, and the positions of the respective second curved segments 15 are also staggered.

[0051] In the same supporting layer, the adjacent side walls 13 have a tendency to lean closer to each other as they approach the joint 16 of the adjacent supporting layers; and at the joint 16 of the adjacent supporting layers, in the same supporting layer, the starting point of the first curved section 14 of the side wall 13 is connected to the end point of the first curved section 14 of the other adjacent side wall 13 that is staggered therewith, and the starting point of the second curved section 15 of the side wall 13 is connected to the end point of the second curved section 15 of the other adjacent side wall 13 that is staggered therewith, so that the support channels 12 in the adjacent supporting layers are connected.

[0052] The starting points and end points of the first curved section 14 and the second curved section 15 in the side wall 13 are inclined along the extension direction of the corresponding support channel 12, and the corresponding inclination directions of the first curved section 14 and the second curved section 15 in the same side wall 13 are the same, and the corresponding inclination directions in adjacent side walls 13 are opposite.

[0053] The closer the side wall 13 is to the joint 16 of the adjacent support layers, the greater the curvature thereof.

[0054] Among them, Figure 1 The orientation shown is used as a reference to define the top and the bottom, and to define mutually perpendicular arrangement directions and channel directions in the horizontal direction. The arrangement directions and channel directions here are relative to each supporting layer, and are not absolute directions.

[0055] Reference Figure 2 and Figure 3 , which is a schematic cross-sectional view of the high-resilience structure of the sole involved in this embodiment at different heights in the horizontal direction, Figure 2 The cross section in Figure 3 Because the sole rebound boosting structure provided in this embodiment is prepared by 3D printing, the overall structure is built by stacking layers from bottom to top, and this specification also describes the structure in this way.

[0056] Reference Figure 2 The part located in the outline is the support layer, the main body of the support layer is the side wall 1342 used to form the support channel 1241, and the space between the two side walls 1342 is the support channel 1241. Although the side wall 1342 has a curved structure, the support channel 1241 generally extends in a fixed direction, and its extension direction is the channel direction of the support layer.

[0057] At the same time, refer to Figure 4, which shows the structure of the bottom support layer in the high-resilience structure of the sole. The bottom support layer includes a plurality of support channels 1241, which are arranged along a fixed direction, that is, the arrangement direction corresponding to the support layer. Figure 4 As an example, in this top view, there are defined left-right direction and front-back direction. Here, the front-back direction is Figure 3 The up-down direction in the view, but to distinguish it from the up-down direction mentioned above, it is defined as the front-to-back direction. At this time, the channel direction of the bottom support layer is the front-to-back direction, and the arrangement direction is the left-to-right direction. Figure 5 , which also shows the structure of the bottom support layer of the high-resilience structure of the sole, and Figure 4 The difference is that Figure 5 Compared with the support layer Figure 4 The support layers in the stack are higher and closer to the penultimate support layer.

[0058] Reference Figure 6 , which shows the situation of the penultimate support layer in the high-rebound structure of the sole. It can be seen that in this support layer, the channel direction becomes the left-right direction, and the arrangement direction becomes the up-down direction. It can be seen that for adjacent support layers, the channel direction and arrangement direction are periodically changed. At the same time, the adjacent support layers are interconnected, so the support layers above the rebound layer 11 are interconnected, and the support layers below the rebound layer 11 are also interconnected.

[0059] Reference Figure 4 , the side wall 13 is periodically arranged with the first curved section 14 and the second curved section 15 connected end to end along the front-to-back direction, that is, the channel direction of the support layer. Taking the marked side wall 13 as an example, starting from the front end, the first curved section 14, the second curved section 15, the first curved section 14, the second curved section 15... are arranged in sequence to the rear end, wherein the first curved section 14 starts from the front end and smoothly bends and extends forward to the left, and the second curved section 15 starts from the end point of the first curved section 14, and smoothly bends and extends backward to the right, and the starting point of the first curved section 14 and the end point of the second curved section 15 are at the same position in the left-right direction. Thus, the side wall 13 forms a periodic curved structure.

[0060] The support channel 12 is formed by the cooperation of the side wall 13, and the side wall 13 is provided with a first curved section 14 and a second curved section 15. Compared with the straight side wall 13, the curved side wall 13 has a larger equivalent support area in the arrangement direction. When subjected to downward pressure, the side wall 13 itself can form a certain support, which can then be fed back to the entire support assembly 10, thereby improving the shock-absorbing effect of the sole rebound boosting structure.

[0061] At the same time, refer to Figure 4 , the position of the first curved section 14 on the other side wall 13 to the left of the marked side wall 13, that is, the other side wall 13 adjacent to the marked side wall 13, is staggered, and the position of the second curved section 15 is also staggered. The staggered here means that the position of the start of the first curved section 14 of the marked side wall 13 in the front-to-back direction roughly corresponds to the position of the end of the corresponding first curved section 14 of the adjacent side wall 13. The corresponding position here is not completely opposite, but there is a certain inclination, so that the side wall 13 is inclined in the front-to-back direction.

[0062] Reference Figure 5 , the side wall 13 of the bottom support layer is gradually stacked upward. It can be seen from the figure that the starting and ending points of the first curved section 14 and the second curved section 15 in the side wall 13 of the support layer are inclined along the extension direction of the corresponding support channel 12. In the bottom support layer, the starting and ending points of the first curved section 14 and the second curved section 15 of the marked side wall 13 are inclined toward the rear side, while the starting and ending points of the first curved section 14 and the second curved section 15 of the other side wall 13 adjacent to the marked side wall 13 are inclined toward the front side. In this way, in the same support layer, adjacent side walls 13 have a tendency to be closer to each other as they are closer to the joint 16 of the adjacent support layer.

[0063] Reference Figure 6 , the bottom support layer and the penultimate support layer intersect, and at this time, the top of the side wall 13 of the bottom support layer begins to connect with the adjacent side wall 13, and the connecting position is that the starting point of the first curved section 14 on the side wall 13 connects with the end point of the first curved section 14 on the other side wall 13, and the starting point of the second curved section 15 on the side wall 13 connects with the starting point of the second curved section 15 on the other side wall 13. At the position of the connecting point 16, the side wall 13 of the penultimate support layer begins to extend in the left-right direction. After that, the side walls 13 of the penultimate support layer will gradually lean towards each other until they are connected to form the connecting point 16.

[0064] In the same support layer, adjacent side walls 13 have a tendency to lean closer, and there are connecting parts between adjacent side walls 13. The mutually leaning structures make the force transmission faster and can make the supporting performance of the side walls 13 better. The adjacent side walls 13 are connected, which can make the connecting parts between adjacent support layers more stable, and increase the equivalent contact area of ​​the connecting parts, improve the supporting performance, and thus improve the overall shock absorbing effect. The first curved section 14 and the second curved section 15 are inclined, which can make it easier for adjacent side walls 13 to be connected as a whole, and the connecting positions are staggered to reduce the influence of excessive stress concentration, thereby improving the overall shock absorbing effect. The closer the part of the side wall 13 is to the support layer connection 16, the greater the degree of curvature, which can make the connection between adjacent side walls 13 smoother, avoid sudden changes in the structure, and enhance the resilience of the support assembly 10.

[0065] Reference Figure 2 or Figure 3 , which shows the structure of the rebound layer 11 at different height sections, while referring to Figure 1 It can be seen that the resilience layer 11 has an arched structure, and the upper surface of the resilience layer 11 is connected to the support layer above it, and the lower surface of the resilience layer 11 is connected to the support layer below it. The resilience layer 11 has an arched structure, which can be compared to an inverted bowl for easy understanding.

[0066] The rebound layer 11 is continuously inclined toward the circumference from top to bottom to form an arched structure, and the rebound layer 11 is arranged between the support layers, thereby isolating the support layers on the upper and lower sides of the rebound layer 11; when the support assembly 10 is subjected to force, due to the arched shape of the rebound layer 11, the rebound layer 11 will be subjected to force through the support layer and open to the circumference, at this time, the rebound layer 11 will accumulate elastic potential energy, and when the force is removed, the rebound layer 11 will quickly restore the deformation, thereby making the rebound speed of the high-rebound structure of the sole faster; and, the upper surface of the rebound layer 11 will receive the force of the support layer above it, and the rebound layer 11 will transfer the force to the support layer below it, which is equivalent to quickly and evenly dispersing the force received by the support assembly 10 to the entire support layer assembly through the rebound layer 11, thereby providing better rebound and shock-absorbing effects through the entire support assembly 10; at the same time, the rebound layer 11 will also play a role in pulling the support layer in the horizontal direction, thereby improving the support performance of the support layer and better absorbing impact energy.

[0067] As one aspect of the high-rebound structure of the sole involved in the present invention, when the top of the rebound layer 11 is an open structure, that is, the rebound layer 11 has an opening at the center position, the support layer in the support assembly 10 will not be isolated by the rebound layer 11, and the support layer will be separated by the rebound layer 11 only in the position with the rebound layer 11.

[0068] Alternatively, as another aspect of the high-resilience sole structure of the present invention, the top of the resilience layer 11 is closed to separate the support assembly 10 into an upper support portion 18 located on its upper side and a lower support portion 17 located on its lower side. Figure 1 , Figure 1 In the high-rebound structure of the sole shown, the top of the rebound layer 11 is closed, and the closure here means that there is no opening in the middle of the rebound layer 11, and it also extends continuously on its circumferential side, and is a fully closed structure in the circumferential direction. In this way, the upper support part 18 and the lower support part 17 can only be connected through the rebound layer 11 and the outer cover 20. In this, since the rebound layer 11 divides the entire support assembly 10 into two parts that are isolated from each other, the upper support part 18 and the lower support part 17 can independently compress and restore the air inside, which is equivalent to dividing the support assembly 10 into two smaller spaces to form a chamber, so that the compression and recovery of the air are faster, and the overall rebound rate of the high-rebound structure of the sole is also faster, and the rebound and shock-absorbing effects are better.

[0069] In addition, refer to Figure 2 or Figure 3 , the top of the rebound layer 11 is connected to the top wall of the outer covering layer 20, and the bottom edge of the rebound layer 11 is connected to the bottom wall or side wall 13 of the outer covering layer 20. When the top wall of the outer covering layer 20 receives external force, the force can be directly transferred to the rebound layer 11, and then the force is transferred to the lower support part 17 through the rebound layer 11. At the same time, the upper support part 18 will also receive this force, thereby forming a rapid transmission of force, improving the overall rebound and shock-absorbing performance of the high-rebound structure of the sole. At the same time, the boundary of the rebound layer 11 is limited by the outer covering layer 20 to prevent the rebound layer 11 from excessively deforming outwards. At the same time, the force on the top wall of the outer covering layer 20 can also be transferred to the side wall 13 or bottom wall of the outer covering layer 20 through the rebound layer 11, thereby improving the overall support performance of the high-rebound structure of the sole.

[0070] The high-rebound structure of the sole involved in the embodiment of the present invention includes a support component 10 and an outer covering layer 20, wherein the support component 10 is provided with a support layer and a rebound layer 11, and the outer covering layer 20 closes the outer side of the support component 10, so that the support component 10 forms a seal; the support layer in the support component 10 is provided with a support channel 12, the support channel 12 can accommodate air, and the channel directions of the support channels 12 of adjacent support layers are perpendicular to each other, and the adjacent support layers are interconnected; when the support component 10 is subjected to downward pressure, the support component 10 will be squeezed as a whole, so that the air in the support channel 12 is compressed, and when the pressure is removed, the air will restore its original volume. In this process, the compression and recovery of the air will play a certain shock-absorbing role; at the same time, the adjacent support layers in the up and down directions will support each other, and because the support channels 12 of the adjacent support layers are in a mutually staggered form, when the support component 10 is squeezed, the force received will be quickly and evenly dispersed to the entire support component 10, thereby providing a better shock-absorbing effect through the entire support component 10.

[0071] In addition, an embodiment of the present invention also relates to a sole, which adopts the above-mentioned sole rebound boosting structure, so it has a better wearing feel and shock-absorbing support performance.

[0072] Specifically, the heel portion of the midsole of the sole can adopt the high-rebound structure of the sole involved in the above-mentioned embodiment, and the forefoot and arch portions of the midsole of the sole can adopt other materials, or the same components as the above-mentioned high-rebound structure of the sole can be adopted throughout the palm. However, it should be noted that the external shape of the high-rebound structure of the sole needs to be modified and adjusted accordingly corresponding to the forefoot and arch portions of the midsole.

[0073] The description of the above specification and embodiments is used to explain the protection scope of the present invention, but does not constitute a limitation on the protection scope of the present invention. Through the enlightenment of the present invention or the above embodiments, ordinary technicians in this field can obtain modifications, equivalent substitutions or other improvements to the embodiments of the present invention or part of the technical features thereof through logical analysis, reasoning or limited experiments, which should be included in the protection scope of the present invention.
