Description

Technical Field

[0001] The invention relates to the technical field of spike shoes, and in particular to a sole and spike shoes suitable for sprinting. Background Art

[0002] In track and field sports, sprint events require athletes to quickly accelerate from a stationary state to a maximum speed in a very short period of time, and maintain this speed throughout a given distance. During sprinting, ground grip has a crucial impact on the athlete's performance. For example, when starting, athletes need to accelerate quickly from a stationary state. Higher grip can help athletes better utilize leg strength and reduce slippage, thereby achieving a quick start. During the acceleration process, athletes generate forward propulsion through the interaction between their footsteps and the ground. Good ground grip can increase the friction between the feet and the ground, helping athletes to exert force more effectively and improve acceleration efficiency. In addition, good ground grip can also reduce the risk of sprains or other sports injuries caused by slipping ground during running.

[0003] In order to improve the grip with the ground, sprinters usually wear spiked shoes to increase the grip with the ground. However, current spiked shoes simply add a number of protruding spikes on the sole, which can play a role in improving the grip to a certain extent, but still cannot meet the needs of athletes in sprint events. 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 sole and spikes suitable for sprinting. After the sole is applied to the spikes, the spikes can have good grip and better meet the needs of athletes.

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

[0006] Technical solution 1: A sole suitable for sprinting, comprising: a body, comprising a base and a gripping assembly, wherein the base is arranged in a hollow ring shape in the middle according to the shape of the sole and is located on the periphery of the body, and the gripping assembly is connected to the bottom surface of the base and is located in the middle of the body; the gripping assembly comprises a plurality of gripping units arranged in the extension direction of the body and connected to each other; the gripping unit is provided with a first arm, a second arm and a third arm extending in different directions in the extension direction of the body, the first arm, the second arm and the third arm are connected at the middle position of the gripping unit and form a gripping protrusion protruding toward the bottom side of the body and in a cone shape, and the first arm The angles between the support arm, the second support arm and the third support arm are all obtuse angles; the grip unit is provided with a first connecting portion, a second connecting portion and a third connecting portion between the first support arm and the second support arm, between the second support arm and the third support arm, and between the first support arm and the third support arm, respectively, and the first support arm, the second support arm and the third support arm in each of the grip units are respectively connected to the second connecting portion, the third connecting portion and the first connecting portion in other adjacent grip units, and a hollow hole surrounded by the first support arm, the second support arm and the third support arm is formed between adjacent grip units; a plurality of shoe spikes, which are fixedly mounted on the body and protrude toward the bottom side of the body.

[0007] Technical solution 2 based on technical solution 1: In the gripping unit, the first arm, the second arm and the third arm are formed by an arm seat and an arm edge extending along a preset direction, the arm edge is located on the bottom side of the arm seat and is provided with a ridge protruding toward the bottom side of the main body, and the ridge extends along the extension direction of the arm edge where it is located; the thickness of the arm edge increases as it approaches the gripping protrusion, so that the gripping unit is formed in the middle position by connecting the arm edges of the first arm, the second arm and the third arm to form a triangular pyramid-shaped gripping protrusion.

[0008] Technical solution three based on technical solution one: in the grip units adjacent to each other in the front-to-rear direction of the main body, the extension direction of the first arm of the rear grip unit has a tendency to continue the extension direction of the first arm of the front grip unit, and the first arm of each grip unit as a whole has an extension tendency that is compatible with the extension shape of the main body in the length direction.

[0009] Technical solution four based on technical solution three: the main body corresponds to the distribution of human foot bones from front to back, namely the metatarsal head area, metatarsal body area, cuneiform area and calcaneal area; in the metatarsal head area, based on the extension trend of the first arm of each grip unit, the grip unit close to the inner foot side of the main body is bent toward the outer foot side of the main body in the front-to-back direction of the main body, and the degree of bending decreases as the grip unit approaches the outer foot side of the body.

[0010] Technical solution five based on technical solution four: in the metatarsal body area, based on the extension trend of the first arm of each grip unit, the grip units close to the inner foot side and outer foot side of the main body are bent in the front-to-back direction of the main body, convexly toward the inner foot side and outer foot side of the main body respectively, and the degree of bending decreases as the grip units approach the middle position of the left-right direction of the main body.

[0011] Technical solution 6 based on technical solution 5: in the metatarsal head area, the layout density of each grip unit first increases and then decreases from front to back; the layout density of the grip unit refers to the number of grip units arranged per unit area.

[0012] Technical solution seven based on technical solution six: in the metatarsal body area, a reinforced portion is formed near the inner foot side, where the layout density of the grip unit is greater than that of other portions.

[0013] Technical Solution 8 based on Technical Solution 7: In the cuneiform area, the layout density of each grip unit first increases and then decreases from the inner foot side to the outer foot side of the main body.

[0014] Technical solution nine based on technical solution eight: in the calcaneal region, the layout density of each grip unit is similar.

[0015] Technical solution 10 based on technical solution 4: the arrangement density of the gripping units in the cuneiform area and the calcaneal area is smaller than the arrangement density of the gripping units in the metatarsal head area and the metatarsal body area.

[0016] Technical Solution 11 based on Technical Solution 4: The sharpness of the gripping protrusions of the gripping units in the cuneiform area and the calcaneal area is less than the sharpness of the gripping protrusions of the gripping units in the metatarsal head area and the metatarsal body area.

[0017] Technical solution 12 based on technical solution 4: a plurality of the studs are arranged along the edge of the metatarsal head area.

[0018] Technical solution thirteen based on technical solution twelve: the main body also includes a spike seat, which is connected to the base or the grip assembly and is used to fix the spikes; the grip assembly makes way for the spike seat at the position where the spike seat is provided on the main body, and is connected to the spike seat through the first arm, the second arm and / or the third arm of the grip unit.

[0019] In addition, the present invention also provides technical solution fourteen: a spiked shoe, comprising the sole as described in any one of technical solutions one to thirteen, and also comprising a shoe body, the bottom of which is connected to the top side surface of the sole.

[0020] 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:

[0021] Technical solution 1 provides a sole suitable for sprinting, the sole comprising a body and a plurality of spikes, the spikes can be arranged on the body and protrude toward the bottom side of the body, so that the sole has basic grip;

[0022] At the same time, in coordination with the spikes, the body includes a base and a gripping assembly, the base is used to form a foundation for a stable connection for the gripping assembly, wherein the base is set to a hollowed-out ring shape according to the shape of the sole, so that the vacant position in the middle of the base can be used to set the gripping assembly, and this structure of the base can preliminarily reduce the weight of the body; the gripping assembly is formed by a plurality of gripping units arranged and interconnected in the extension direction of the body, where the extension direction of the body can be regarded as the direction in which the sole is spread out, and the sole is a roughly flat structure; in each gripping unit, a first arm, a second arm and a third arm are provided, and these arms are connected in the middle position to form a conical gripping protrusion, and this structure allows the bottom of the entire body to be covered with conical gripping protrusions, which can be embedded in the ground when the sole touches the ground, thereby increasing the grip of the sole with the ground; and the gripping protrusion of each gripping unit has three arms. The three arms are connected to form a structure, which not only effectively improves the structural stability of the gripping protrusion and reduces the deformation of the gripping protrusion when subjected to force; and when the gripping protrusion is embedded in the ground, it can cooperate with other adjacent gripping units to form a mesh force transmission structure, thereby transmitting the interaction force between the contact part of the sole and the ground to the entire sole, so that the athlete can better exert force; wherein, the angle between the arms of each gripping unit is an obtuse angle, which enables each gripping unit to better withstand the force in different directions, whether it is the forward force at the start or the lateral force during running, etc., can be effectively dealt with; at the same time, the gripping unit of this structure is set, through the mutual connection between the gripping units, while reducing the weight of the sole, it can also effectively improve the structural strength and rigidity of the entire sole, and avoid excessive bending of the sole of the athlete during running;

[0023] In addition, the gripping units are connected to each other through the first, second and third connecting parts to form hollow holes. On the one hand, the connecting parts ensure the integrity of the gripping units, so that the entire gripping assembly works together to improve the overall gripping effect. On the other hand, the hollow holes can reduce the weight of the sole without affecting the gripping force, which meets the requirements of sprinting for the lightness of the shoe body, and helps athletes to swing their feet more flexibly during running and reduce energy loss.

[0024] Therefore, the sole adopting the above structure can provide athletes with good ground grip, and better meet the needs of sprinters for grip when they burst into acceleration in a very short time and maintain high-speed running.

[0025] In technical solution two, the support arm in the grip unit is formed by an arm seat and an arm edge. The arm seat, as the basis of the support arm, can provide good structural strength. A ridge is formed on the arm edge. The ridge extends along the extension direction of the support arm and connects in the middle position of the grip unit to form a triangular pyramid-shaped grip protrusion. The setting of the ridge makes the grip protrusion not only connected to the base part of the grip unit in the middle position of the grip unit, but also connected to the three arms, thereby further enhancing the structural strength of the grip protrusion, and can further reduce the deformation of the grip protrusion when subjected to force, so that the grip protrusion can be better embedded in the ground and improve the grip of the sole with the ground.

[0026] In technical solution three, the arrangement of the grip units in the grip assembly allows the grip units to form a continuous and adaptive grip layout along the length direction of the sole, which can better fit the force sequence and movement trajectory of the athlete's feet from back to front during running, ensuring that continuous, stable and effective grip can be provided during the connection process of each step, avoiding slipping due to discontinuous grip or uneven force, and helping athletes to accelerate smoothly and maintain high-speed running.

[0027] In technical solution four, the metatarsal head area is the main area where athletes come into contact with the ground when running. Therefore, the grip unit in the metatarsal head area has a bent structure, which can enable the sole to adapt to the rolling movement and force state of the athlete's foot in this area, and the change in the degree of bending adapts to the force differences at different positions of the metatarsal head area of ​​the athlete's foot during running, which can enable the grip unit to better fit the ground and make the grip more uniform and effective in this critical foot force area.

[0028] In technical solution five, the grip unit in the metatarsal body area presents a structure that is bent on both sides and straight in the middle, which can better transfer the force of the grip unit in the metatarsal head area to the calcaneal area, and can match the force conditions of the foot at different positions. Whether it is the inner and outer sides of the foot that exert force or the transition movement in this area, good grip support can be obtained.

[0029] In technical solution six, in the metatarsal head area, the layout density of each grip unit first increases and then decreases from front to back. During the athlete's running, the middle position in the front-to-back direction of the metatarsal head area is the more important area in contact with the ground. Increasing the layout density of the grip units in this area can make the grip protrusions denser in this area, thereby providing a stronger grip. At the same time, in the part outside this area, the density of the grip protrusions can be slightly reduced, thereby reducing the weight of the main body of the metatarsal head area.

[0030] In Technical Solution 7, a reinforced portion with a higher density of grip units than other portions is formed in the metatarsal body area, near the inner foot side. The reinforced portion is located at a key position for transmitting force from the metatarsal head area to other posterior areas of the sole. In addition, due to the bending of the forefoot of the athlete's foot, this area will be subjected to relatively greater pressure and unbalanced force. By increasing the density of grip units in this area, not only can the grip here be strengthened to prevent slipping or affecting the force effect due to insufficient grip on the inner foot side, but also the strength of the sole in this area can be enhanced, thereby improving the rolling and rebound effects of the sole on the athlete's foot.

[0031] In Technical Solution 8, in the cuneiform area, the layout density of each grip unit first increases and then decreases from the inner foot side to the outer foot side of the body, that is, a strip-shaped area with higher structural strength is formed in the middle position. This strip-shaped area can effectively transfer the force of the metatarsal head area and the metatarsal body area to the calcaneal area, ensuring a smooth transition and effective force of the athlete's foot here.

[0032] In technical solution nine, in the calcaneal area, the layout density of each grip unit is similar, so that the sole can provide stable and balanced support in the calcaneal area, so that the athlete's heel can smoothly contact the ground and transmit force during landing and pushing off the ground.

[0033] In Technical Solution 10, the layout density of the grip units in the cuneiform area and the calcaneal area is lower than that in the metatarsal head area and the metatarsal body area. Since the metatarsal head area and the metatarsal body area are the main force-generating parts of athletes during sprinting, stronger and denser grip is required to meet the needs of quick start and acceleration; while the cuneiform area and the calcaneal area mainly focus on stable support, the relatively low layout density ensures basic grip while avoiding unnecessary weight increase, making the overall performance of the sole more in line with the characteristics of sprinting, optimizing the functional distribution of each area, and improving the overall running effect.

[0034] In technical solution eleven, the gripping protrusions of the gripping units in the cuneiform area and the calcaneal area are sharper than the gripping protrusions of the gripping units in the metatarsal head area and the metatarsal body area. The sharper gripping protrusions can provide better gripping and embedding effects, thereby achieving rapid force and acceleration. The cuneiform area and the calcaneal area mainly play a role in stabilizing support, and the relatively blunt gripping protrusions are sufficient to ensure stable contact with the ground.

[0035] In technical solution twelfth, multiple studs are arranged along the edge of the metatarsal head area, which can enable the studs to work synergistically with the gripping units in the metatarsal head area to enhance the gripping performance during the starting and acceleration stages.

[0036] In the technical solution thirteen, the main body is provided with a spike seat for fixing the spikes, the grip assembly makes way for the spike seat at the position where the spike seat is provided, and is connected to the spike seat through the support arm of the grip unit; this design not only ensures that the spikes can be firmly installed on the sole, but also makes the grip assembly and the spike seat reasonably cooperate, realizes the compactness and integrity of the sole structure, avoids mutual interference between the various components, and ensures that the grip assembly and the spikes can fully play their respective roles in improving grip.

[0037] Technical Solution 14 provides a spike shoe. By applying a sole with excellent grip performance to the overall structure of the spike shoe, the spike shoe can comprehensively exert the advantages of the sole in all aspects, meet the high requirements of sprinters for grip during the entire sprint process, help athletes to better perform their levels, and reduce the risk of sports injuries caused by insufficient grip. Compared with the existing spike shoes with simple designs, it can better adapt to the characteristics of sprint events and improve athletes' sports performance. BRIEF DESCRIPTION OF THE DRAWINGS

The base 11 is set to be a hollow ring in the middle according to the shape of the sole and is located at the periphery of the body 10. The gripping assembly 12 is connected to the bottom surface of the base 11 and is located in the middle of the body 10; the gripping assembly 12 includes a plurality of gripping units 13 arranged in the extension direction of the body 10 and connected to each other; the gripping unit 13 is provided with a first arm 131, a second arm 132 and a third arm 133 extending in different directions in the extension direction of the body 10, the first arm 131, the second arm 132 and the third arm 133 are connected at the middle position of the gripping unit 13 and form a gripping protrusion 134 protruding toward the bottom side of the body 10 and in a cone shape, and the first arm 131, The angles between the second arm 132 and the third arm 133 are both obtuse angles; the gripping unit 13 is provided with a first connecting portion 135, a second connecting portion 136 and a third connecting portion 137 between the first arm 131 and the second arm 132, between the second arm 132 and the third arm 133, and between the first arm 131 and the third arm 133, respectively, and the first arm 131, the second arm 132 and the third arm 133 in each of the gripping units 13 are respectively connected to the second connecting portion 136, the third connecting portion 137 and the first connecting portion 135 in other adjacent gripping units 13, and a hollow hole 14 enclosed by the first arm 131, the second arm 132 and the third arm 133 is formed between adjacent gripping units 13.

[0056] Specifically, first refer to Figure 1 and Figure 2The body 10 includes a base 11 and a grip assembly 12, wherein the base 11 is an annular structure, the periphery of which is set according to the shape required by the sole, and extends inward by a certain distance to form a hollow in the middle part of the base 11. The grip assembly 12 includes a plurality of grip units 13, which are arranged and connected to each other in the extension direction of the body 10, and the shape of the outer edge of the grip assembly 12 is adapted to the shape of the base 11, and the grip units 13 on the outer side of the grip assembly 12 are connected to the bottom surface of the base 11, so that the grip assembly 12 is connected to the base 11. In practical applications, the base 11 and the grip assembly 12 can be formed together.

[0057] The structure of the grip unit 13 in the grip assembly 12 is shown in FIG. Figure 3 and Figure 4 Each gripping unit 13 is provided with a first arm 131, a second arm 132 and a third arm 133. Through the extension of the first arm 131, the second arm 132 and the third arm 133, the gripping unit 13 forms an open structure. The first arm 131, the second arm 132 and the third arm 133 each have their own extension direction, and the angles between them are all obtuse angles, which makes each gripping unit 13 have good structural strength in multiple directions. The first arm 131, the second arm 132 and the third arm 133 are connected at the middle position of the gripping unit 13, and form a gripping protrusion 134 protruding toward the bottom side of the body 10. The gripping protrusion 134 is cone-shaped and can be embedded in the ground when the sole contacts the ground to improve the grip. A first connecting portion 135 is formed between the first arm 131 and the second arm 132, a second connecting portion 136 is formed between the second arm 132 and the third arm 133, and a third connecting portion 137 is formed between the first arm 131 and the third arm 133. Figure 4Taking the grip unit 13 in the middle as an example, a grip unit 13 is provided at the upper left corner, the upper right corner, the lower left corner, the lower right corner, the upper part, and the lower part of the grip unit 13, wherein the end of the third arm 133 of the grip unit 13 at the upper left corner is connected to the first connection part 135 of the grip unit 13, the end of the second arm 132 of the grip unit 13 at the upper right corner is connected to the third connection part 137 of the grip unit 13, the end of the first arm 131 of the grip unit 13 at the lower part is connected to the second connection part 136 of the grip unit 13, and the first arm 133 of the grip unit 13 at the upper right corner is connected to the third connection part 137 of the grip unit 13. The end of the grip unit 131 is connected to the second connection part 136 of the grip unit 13 above it, the end of the second arm 132 of the grip unit 13 is connected to the third connection part 137 of the grip unit 13 below it, and the end of the third arm 133 of the grip unit 13 is connected to the first connection part 135 of the grip unit 13 below it. At the same time, between the three adjacent grip units 13, a hollow hole 14 is formed by the first arm 131 of one of the grip units 13, the second arm 132 of another grip unit 13 and the third arm 133 of the third grip unit 13. By analogy, the first arm 131, the second arm 132 and the third arm 133 of each grip unit 13 are connected to the second connection portion 136, the third connection portion 137 and the first connection portion 135 of the other three adjacent grip units 13, and the first connection portion 135, the second connection portion 136 and the third connection portion 137 of each grip unit 13 are also connected to the third arm 133, the first arm 131 and the second arm 132 of the other three adjacent grip units 13. In this way, the grip units 13 in the grip assembly 12 are connected to each other to form a mesh structure.

[0058] Continue to refer to Figure 3 and Figure 4 In the gripping unit 13, the first arm 131, the second arm 132 and the third arm 133 are formed by an arm seat 15 and an arm ridge 16 extending along a preset direction, the arm ridge 16 is located at the bottom side of the arm seat 15 and is provided with a ridge 161 protruding toward the bottom side of the body 10, and the ridge 161 extends along the extension direction of the arm ridge 16 where it is located; the thickness of the arm ridge 16 increases as it approaches the gripping protrusion 134, so that the gripping unit 13 is connected at the middle position by the arm ridges 16 of the first arm 131, the second arm 132 and the third arm 133 to form a triangular pyramid-shaped gripping protrusion 134.

[0059] Specifically, the arm seat 15 can be regarded as the base part on the first arm 131, the second arm 132 and the third arm 133, which has a certain thickness and can be regarded as a structure extending roughly on a plane. The arm ridge 16 can be regarded as a part connected to the arm seat 15 and located on the bottom side of the arm seat 15. In fact, the grip unit 13 is integrally formed and is not divided into two different components in the actual structure. Among them, the arm ridge 16 is a protruding structure on the arm seat 15, which extends from the free end of the arm seat 15 toward the middle position of the grip unit 13 and gradually thickens. At the same time, the arm ridge 16 forms a ridge 161 similar to a ridge, and the two sides of the ridge 161 are inclined slopes, thereby protruding to form a ridge-like structure. The ridges 161 of the first arm 131 , the second arm 132 and the third arm 133 are connected at the middle position of the gripping unit 13 , and the three ridges 161 cooperate to form a triangular pyramid-shaped gripping protrusion 134 , and the end of the gripping protrusion 134 is the overlapping point of the three ridges 161 . The support arm in the grip unit 13 is formed by an arm seat 15 and an arm ridge 16. The arm seat 15, as the basis of the support arm, can provide good structural strength. A ridge 161 is formed on the arm ridge 16. The ridge 161 extends along the extension direction of the support arm and connects at the middle position of the grip unit 13 to form a triangular pyramid-shaped grip protrusion 134. The setting of the ridge 161 makes the grip protrusion 134 not only connected to the base part of the grip unit 13 at the middle position of the grip unit 13, but also connected to the three arms, thereby further enhancing the structural strength of the grip protrusion 134, and can further reduce the deformation of the grip protrusion 134 when subjected to force, so that the grip protrusion 134 can be better embedded in the ground and improve the grip of the sole with the ground.

[0060] As one aspect of the sole suitable for sprinting involved in the present embodiment, in the grip units 13 adjacent to each other in the front-to-rear direction of the main body 10, the extension direction of the first arm 131 of the rear grip unit 13 has a tendency to continue the extension direction of the first arm 131 of the front grip unit 13, and the first arm 131 of each grip unit 13 as a whole has an extension tendency that is compatible with the extension shape of the main body 10 in the length direction.

[0061] Specifically, refer to Figure 3 It can be seen that in the grip assembly 12, the first arm 131 extends roughly along the front-to-back direction of the body 10, and the extension direction of the first arm 131 of each grip unit 13 corresponds to the position of the second connection portion 136 on the grip unit 13, so when the first arm 131 of the next grip unit 13 is connected to the second connection portion 136 of the previous grip unit 13, the first arms 131 of the two grip units 13 have a tendency to form the extension direction of the two grip units 13. Of course, the other second arms 132 and third arms 133 can also form a similar extension tendency, but refer to Figure 1 and Figure 2 In the sole of the present embodiment, the arrangement of the gripping unit 13 formed by the extension direction of the first arm 131 has a specific function. It should be noted that since the extension shape of the body 10 in the length direction is not straight, the inner foot side 31 and the outer foot side 32 thereof are bent to different degrees and in different directions in the front-back direction, and the first arm 131 of each gripping unit 13 is designed as a whole to have an extension trend that matches the extension shape of the body 10 in the length direction, that is, each gripping unit 13 is designed to have an extension trend that is more suitable for the shape of the inner foot side 31 and the outer foot side 32 according to its position relative to the inner foot side 31 and the outer foot side 32. The arrangement of the grip units 13 in the grip assembly 12 enables the grip units 13 to form a continuous and adaptive grip layout in the length direction of the sole, which can better fit the force sequence and movement trajectory of the athlete's feet from back to front during running, ensuring that continuous, stable and effective grip can be provided during the connection process of each step, avoiding slipping due to discontinuous grip or uneven force, and helping athletes to accelerate smoothly and maintain high-speed running.

[0062] Among them, refer to Figure 2 , the body 10 corresponds to the distribution of bones of the human foot from front to back, namely the metatarsal head area 21, the metatarsal body area 22, the cuneiform area 22 and the calcaneal area 24. It should be understood that the above division of different areas on the body 10 is only a rough division based on the distribution of bones of the human foot, and there is no strict dividing line between adjacent areas. Those skilled in the art can understand the approximate range of each area and use it to realize the structure of the sole involved in this embodiment.

[0063] In the metatarsal head region 21, based on the extension trend of the first arm 131 of each grip unit 13, the grip unit 13 close to the inner foot side 31 of the body 10 is bent toward the outer foot side 32 of the body 10 in the front-to-back direction of the body 10, and the degree of bending decreases as the grip unit 13 approaches the outer foot side 32 of the body 10. In addition, in the metatarsal head region 21, the layout density of each grip unit 13 increases first and then decreases from front to back; the layout density of the grip unit 13 refers to the number of grip units 13 laid out per unit area.

[0064] In the metatarsal body region 22, based on the extension trend of the first arm 131 of each gripping unit 13, the gripping units 13 close to the inner foot side 31 and the outer foot side 32 of the body 10 are bent in the front-back direction of the body 10, protruding toward the inner foot side 31 and the outer foot side 32 of the body 10, respectively, and the bending degree decreases as the gripping unit 13 approaches the middle position in the left-right direction of the body 10. In addition, in the metatarsal body region 22, a reinforcement portion 17 is formed near the inner foot side 31, where the layout density of the gripping units 13 is greater than that of other portions.

[0065] Specifically, refer to Figure 2 In the metatarsal head region 21, the plurality of gripping units 13 near the inner foot side 31 of the body 10, with the extension trend of the first arm 131 of the gripping unit 13 as a reference, these gripping units 13 are convex and bent toward the outer foot side 32 of the body 10. The bending of the gripping unit 13 here is formed by the mutual cooperation of the first arms 131 of the plurality of gripping units 13. The specific setting method can be that the first arm 131 of the gripping unit 13 located at the front end first extends obliquely from the inner foot side 31 to the outer foot side 32 from front to back, and the inclination angle of the first arm 131 of the next gripping unit 13 located after the gripping unit 13 is slightly reduced, and the subsequent gripping units 13 are set in the same way until the inclination angle of the first arm 131 on the gripping unit 13 is changed to extend from the inner foot side 31 to the outer foot side 32 from front to back. During the bending process, the first arm 131 of each grip unit 13 may be slightly bent, or the position where the first arm 131 of each grip unit 13 is connected to the second connection portion 136 of the previous grip unit 13 may be slightly offset from the first arm 131 of the grip unit 13. The metatarsal head area 21 is the main area where athletes contact the ground when running, so the grip unit 13 in the metatarsal head area 21 has a bent structure, which can make the sole adapt to the rolling action and force state of the athlete's foot at this position, and the change in the degree of bending adapts to the force difference at different positions of the metatarsal head area 21 of the athlete's foot during running, which can make the grip unit 13 better fit the ground, and make the grip force in this key foot force area more uniform and effective.

[0066] Similarly, the arrangement of the gripping units 13 in the metatarsal body region 22 and the cuneiform region 22 can be set with reference to the arrangement of the gripping units 13 in the metatarsal head region 21, and no further details are given here. The gripping units 13 in the metatarsal body region 22 present a structure that is bent on both sides and straight in the middle, which can better transfer the force of the gripping units 13 in the metatarsal head region 21 to the calcaneal region 24, and can match the force conditions of the foot at different positions, so that good gripping support can be obtained regardless of the inner and outer side force of the foot or the transitional movement in this area.

[0067] Moreover, in the metatarsal head region 21, the arrangement density of the gripping units 13 also shows a trend of increasing first and then decreasing from front to back, that is, the arrangement density of the gripping units 13 is small in the front and rear parts of the metatarsal head region 21, and the arrangement density of the gripping units 13 is large in the middle part. During the running process of the athlete, the middle position in the front-to-back direction of the metatarsal head region 21 is the more important area in contact with the ground. Increasing the arrangement density of the gripping units 13 in this part of the region can make the gripping protrusions 134 denser in this part of the region, thereby providing a stronger gripping force. At the same time, the density of the gripping protrusions 134 outside this part of the region can be slightly reduced, thereby reducing the weight of the body 10 of the metatarsal head region 21.

[0068] At the same time, in the metatarsal body area 22, a reinforcement part 17 with a concentrated and increased density of the gripping units 13 is arranged near the inner foot side 31, and the arrangement density of the gripping units 13 is reduced in the part outside the reinforcement part 17. The reinforcement part 17 is just at the key position of transmitting force from the metatarsal head area 21 of the sole to other areas on the rear side, and in this area, due to the bending of the forefoot of the athlete's foot, it will bear relatively greater pressure and uneven force. By increasing the arrangement density of the gripping units 13 in this part of the area, not only can the gripping force here be strengthened to prevent problems such as slipping or affecting the force effect due to insufficient gripping force on the inner foot side 31, but also the strength of the sole in this part of the area can be enhanced to improve the rolling and rebounding effects of the sole on the athlete's foot.

[0069] In addition, in the cuneiform region 22, the layout density of the gripping units 13 increases first and then decreases from the inner foot side 31 to the outer foot side 32 of the body 10. Thus, a strip-shaped region with higher structural strength is formed in the middle position, and the strip-shaped region can effectively transfer the force of the metatarsal head region 21 and the metatarsal body region 22 to the calcaneal region 24, ensuring the smooth transition and effective force of the athlete's foot at this location.

[0070] Furthermore, in the calcaneal region 24, the layout density of each of the gripping units 13 is similar, so that the sole can provide stable and balanced support in the calcaneal region 24, so that the athlete's heel can stably contact the ground and transmit power during landing and pushing off the ground.

[0071] Furthermore, the arrangement density of the gripping units 13 in the cuneiform region 22 and the calcaneal region 24 is lower than that in the metatarsal head region 21 and the metatarsal body region 22. Since the metatarsal head region 21 and the metatarsal body region 22 are the main force generating parts of athletes during sprinting, stronger and denser gripping forces are required to meet the requirements of rapid start and acceleration; while the cuneiform region 22 and the calcaneal region 24 mainly focus on stable support, the relatively low arrangement density ensures basic gripping forces while avoiding unnecessary weight increase, making the overall performance of the sole more in line with the characteristics of sprinting, optimizing the functional distribution of each region, and improving the overall running effect.

[0072] In addition, the sharpness of the gripping protrusions 134 of the gripping unit 13 in the cuneiform region 22 and the calcaneal region 24 is less than the sharpness of the gripping protrusions 134 of the gripping unit 13 in the metatarsal head region 21 and the metatarsal body region 22. The sharpness referred to here can be regarded as the trend of the angle change of the three ridges 161 starting from the end of the gripping protrusion 134 compared with the extension direction of the sole. If the angle change trend is large, it is considered to be sharp. If the angle change trend is small, it is considered to be small. The sharper gripping protrusions 134 can provide a better gripping embedding effect, thereby achieving rapid force and acceleration. The cuneiform region 22 and the calcaneal region 24 mainly play a stable supporting role, and the relatively blunt gripping protrusions 134 are sufficient to ensure stable contact with the ground.

[0073] Reference Figure 2 , the spikes are arranged in plurality along the edge of the metatarsal head region 21. The body 10 further comprises a spike seat 18, the spike seat 18 is connected to the base 11 or the gripping assembly 12, and is used to fix and install the spikes; the gripping assembly 12 makes way for the spike seat 18 at the position where the body 10 is provided with the spike seat 18, and is connected to the spike seat 18 through the first arm 131, the second arm 132 and / or the third arm 133 of the gripping unit 13. In this embodiment, the number of spikes is seven, three of which are located on the inner foot side 31, three are located on the outer foot side 32, and one is located in the middle position, and the spike located in the middle position is roughly at the connection position between the metatarsal head region 21 and the metatarsal body region 22. By arranging the spikes, the spikes can cooperate with the gripping unit 13 of the metatarsal head region 21 to enhance the gripping performance in the starting and acceleration stages. At the same time, a spike seat 18 is provided on the main body 10, which ensures that the spikes can be firmly installed on the sole, and makes the gripping assembly 12 and the spike seat 18 cooperate reasonably, thereby realizing the compactness and integrity of the sole structure, avoiding mutual interference between the various components, and ensuring that the gripping assembly 12 and the spikes can fully play their respective roles in improving grip.

[0074] The shoe sole suitable for sprinting involved in the embodiment of the present invention includes a body 10 and a plurality of spikes. The spikes can be arranged on the body 10 and protrude toward the bottom side of the body 10, so that the sole has basic grip. At the same time, in cooperation with the spikes, the body 10 includes a base 11 and a grip assembly 12. The base 11 is used to form a foundation for a stable connection for the grip assembly 12, wherein the base 11 is arranged as a hollow ring in the middle according to the shape of the sole, so that the empty position in the middle of the base 11 can be used to set the grip assembly 12, and this structure of the base 11 can initially reduce the weight of the body 10; the grip assembly 12 is formed by a plurality of grip units 13 arranged in the extension direction of the body 10 and connected to each other, and the body 10 here is The extension direction can be regarded as the direction in which the sole is spread out, and the sole is roughly a flat structure; in each grip unit 13, a first arm 131, a second arm 132 and a third arm 133 are provided, and these arms are connected in the middle position to form a conical grip protrusion 134. This structure allows the bottom of the entire body 10 to be covered with conical grip protrusions 134, and the grip protrusions 134 can be embedded in the ground when the sole touches the ground, thereby increasing the grip of the sole with the ground; and the grip protrusions 134 of each grip unit 13 are formed by connecting three arms, which not only effectively improve the structural stability of the grip protrusions 134, but also reduce the deformation of the grip protrusions 134 when subjected to force; and in the grip protrusions When 134 is embedded in the ground, it can cooperate with other adjacent gripping units 13 to form a mesh-like force transmission structure, so as to transmit the interaction force between the contact part of the sole and the ground to the entire sole, so that the athlete can better exert force; wherein, the angle between the two arms of each gripping unit 13 is an obtuse angle, which enables each gripping unit 13 to better withstand the force in different directions, whether it is the forward force at the start or the lateral force during running, etc., can be effectively dealt with; at the same time, the gripping units 13 of this structure are arranged, and the gripping units 13 are interconnected, while reducing the weight of the sole, the structural strength and rigidity of the entire sole can also be effectively improved to avoid movement. In addition, the gripping units 13 are connected to each other through the first, second and third connecting parts to form hollow holes 14. On the one hand, the connecting parts ensure the integrity of the gripping units 13, so that the entire gripping assembly 12 works together to improve the overall gripping effect. On the other hand, the hollow holes 14 can reduce the weight of the sole without affecting the gripping force, which meets the requirements of sprinting for lightness of the shoe body, helps athletes to swing their feet more flexibly during running and reduce energy loss. Therefore, the sole adopting the above structure can provide athletes with good ground grip and better meet the needs of sprinters for grip when they burst into acceleration in a very short time and maintain high-speed running.

[0075] The spike shoes involved in the embodiments of the present invention, by applying a sole with excellent grip performance to the overall structure of the spike shoes, enable the spike shoes to comprehensively exert the advantages of the soles in various aspects, meet the high requirements of sprinters for grip during the entire sprinting process, help athletes to better perform their skills, and reduce the risk of sports injuries caused by insufficient grip. Compared with existing spike shoes with simple designs, the spike shoes can better adapt to the characteristics of sprinting events and improve athletes' sports performance.

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.
