Description

Technical Field

[0001] This utility model relates to the field of spiked shoe technology, specifically to a sole and spiked shoe suitable for sprinting. Background Technology

[0002] In track and field, sprint events require athletes to rapidly accelerate from a standstill to their maximum speed in a very short time and maintain that speed for a given distance. During sprinting, ground grip has a crucial impact on athlete performance. For example, at the start, athletes need to accelerate quickly from a standstill; higher grip helps athletes better utilize leg power, reduces slippage, and thus achieves a rapid start. During acceleration, athletes generate forward propulsion through the interaction between their feet and the ground; good ground grip increases friction between the foot and the ground, helping athletes generate power more effectively and improving acceleration efficiency. Furthermore, good ground grip can reduce the risk of sprains or other sports injuries caused by slippery surfaces during running.

[0003] To improve grip on the ground, sprinters typically wear spikes. However, current spikes are simply shoes with a few protruding spikes on the sole. While they can improve grip to some extent, they still cannot meet the needs of athletes in sprinting events. Utility Model Content

[0004] The purpose of this invention is to overcome the aforementioned defects or problems in the prior art and to provide a sole and spikes suitable for sprinting. When this sole is applied to spikes, the spikes can have good grip and better meet the needs of athletes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Technical Solution 1: A shoe sole suitable for sprinting, comprising: a body, which includes a base and a grip component; the base is configured as a ring with a hollow center and located on the outer periphery of the body, according to the shape of the sole; the grip component is connected to the bottom surface of the base and located in the middle of the body; the grip component includes a plurality of grip units arranged and interconnected in the extension direction of the body; each grip unit has 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 connect at the middle position of the grip unit and form a cone-shaped grip protrusion protruding towards the bottom side of the body, and the first arm... The included angles between each pair of the first, second, and third arms are all obtuse angles; the grip unit is provided with a first connecting part, a second connecting part, and a third connecting part between the first and second arms, between the second and third arms, and between the first and third arms, respectively, and the first, second, and third arms in each grip unit are respectively connected to the second connecting part, the third connecting part, and the first connecting part in the adjacent grip unit, and a hollow hole formed by the first, second, and third arms is formed between adjacent grip units; a plurality of shoe nails are fixedly installed 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 arm bases and arm ridges extending along a preset direction. The arm ridge is located on the bottom side of the arm base and has a ridge protruding towards the bottom side of the body. The ridge extends along the extension direction of the arm ridge. The thickness of the arm ridge increases as it approaches the gripping protrusion, so that the gripping unit forms a triangular pyramid-shaped gripping protrusion at the middle position by the arm ridges of the first arm, the second arm, and the third arm connecting together.

[0008] Technical Solution 3 based on Technical Solution 1: In the adjacent gripping units in the front-rear direction of the main body, the extension direction of the first arm of the rear gripping unit tends to continue the extension direction of the first arm of the front gripping unit, and the first arm of each gripping unit as a whole has an extension trend that is adapted to the extension shape of the main body in the length direction.

[0009] Technical Solution 4 based on Technical Solution 3: The body corresponds to the distribution of human foot bones from front to back as the metatarsal head region, metatarsal body region, cuneiform region and calcaneal region; in the metatarsal head region, based on the extension trend of the first arm of each gripping unit, the gripping unit near the inner foot side of the body is bent in the front-back direction of the body towards the outer foot side of the body, and the degree of bending decreases as the gripping unit approaches the outer foot side of the body.

[0010] Technical Solution 5 based on Technical Solution 4: In the metatarsal body region, based on the extension trend of the first arm of each gripping unit, the gripping units near the inner foot side and outer foot side of the body are bent in the front-back direction of the body, respectively protruding towards the inner foot side and outer foot side of the body, and the degree of bending decreases as the gripping unit approaches the middle position in the left-right direction of the body.

[0011] Technical Solution Six based on Technical Solution Five: In the metatarsal head region, the deployment density of each of the gripping units increases from front to back and then decreases; the deployment density of the gripping units refers to the number of gripping units deployed per unit area.

[0012] Technical solution seven based on technical solution six: In the metatarsal body region, a reinforcement section is formed in the part near the inner foot side where the density of the gripping unit is greater than that in other parts.

[0013] Technical solution eight based on technical solution seven: In the wedge bone region, the deployment density of each of the gripping units first increases and then decreases from the inner foot side to the outer foot side of the body.

[0014] Technical solution nine based on technical solution eight: In the calcaneal region, the arrangement density of each of the gripping units is equivalent.

[0015] Technical Solution 10 based on Technical Solution 4: The arrangement density of the gripping units in the cuneiform and calcaneal regions is less than the arrangement density of the gripping units in the metatarsal head and metatarsal body regions.

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

[0017] Technical solution 12 based on technical solution 4: The shoe nails are arranged in multiple ways along the edge of the metatarsal head region.

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

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

[0020] As can be seen from the above description of this utility model, compared with the prior art, this utility model has the following beneficial effects:

[0021] Technical solution one provides a shoe sole suitable for sprinting, the shoe sole including a body and a number of spikes, the spikes can be set on the body and protrude toward the bottom side of the body, so that the shoe sole has basic grip;

[0022] Simultaneously, in conjunction with the cleats, the main body includes a base and a traction component. The base serves as a stable foundation for the traction component, and its shape, based on the sole, is a hollowed-out ring. This allows the traction component to be installed in the central space, and this structure of the base initially reduces the weight of the main body. The traction component is formed by multiple traction units arranged and interconnected along the extension direction of the main body, which can be considered as the direction in which the sole unfolds, and the sole is roughly flat. Each traction unit has a first arm, a second arm, and a third arm, which connect at the middle to form a conical traction protrusion. This structure allows the entire bottom of the main body to be covered with conical traction protrusions, which embed into the ground when the sole touches the ground, thereby increasing the grip between the sole and the ground. Each traction unit's traction protrusion is supported by three arms. The interconnected structure of these three arms not only effectively improves the structural stability of the grip protrusions and reduces their deformation under stress, but also, when the grip protrusions are embedded in the ground, they can cooperate with adjacent grip units to form a mesh-like force transmission structure. This transfers the interaction force between the contact points between the sole and the ground to the entire sole, allowing athletes to generate more power. Furthermore, the obtuse angle between each pair of grip units' arms allows each unit to better withstand forces in different directions, effectively handling forward momentum at the start and lateral forces during running. Simultaneously, this interconnected structure reduces sole weight while effectively increasing the overall structural strength and rigidity of the sole, preventing excessive bending of the sole during running.

[0023] In addition, the grip units are interconnected through the first, second, and third connecting parts, forming perforations. On the one hand, the connecting parts ensure the integrity between the grip units, enabling the entire grip assembly to work together and improve the overall grip effect. On the other hand, the perforations can reduce the weight of the sole without affecting the grip force, meeting the requirements of sprinting for lightweight shoes, and helping athletes swing their feet more flexibly during running, reducing energy loss.

[0024] Therefore, the sole with the above structure can provide athletes with good ground grip, better meeting the grip needs of sprinters when they need to accelerate rapidly in a very short time and maintain high speed.

[0025] In technical solution two, the support arm in the grip unit is formed by the support arm base and the support arm ridge. The support arm base, as the foundation of the support arm, can provide good structural strength. Ridges are formed on the support arm ridge. The ridges extend along the extension direction of the support arm and connect at the middle position of the grip unit to form a triangular pyramid-shaped grip protrusion. The ridges make the grip protrusion not only connected to the base part of the grip unit at the middle position of the grip unit, but also connected to the three support arms, thereby further enhancing the structural strength of the grip protrusion. This can further reduce the deformation of the grip protrusion under force, allowing the grip protrusion to better embed into 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 component creates a continuous and adaptable grip layout along the length of the sole. This better matches the athlete's footwork sequence and movement trajectory from back to front during running, ensuring continuous, stable, and effective grip during each step. This avoids slippage caused by discontinuous grip or uneven force distribution, helping athletes accelerate smoothly and maintain high-speed running.

[0027] In technical solution four, the metatarsal head area is the main area of ​​contact between the athlete and the ground when running. Therefore, the grip unit in the metatarsal head area has a flexed structure, which allows the sole to adapt to the rolling motion and force exertion of the athlete's foot in this area. The change in the degree of flexion adapts to the force differences in different positions of the athlete's foot in the metatarsal head area during running, which allows the grip unit to better fit the ground and makes the grip force more even and effective in this key force exertion area of ​​the foot.

[0028] In technical solution five, the grip unit in the metatarsal body region has a structure that is bent on both sides and straight in the middle. This structure can better transfer the force of the grip unit in the metatarsal head region to the calcaneal region and can match the force of the foot in different positions. Whether it is the force exerted on the inner or outer side of the foot or the transition movement in this area, it can get good grip support.

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

[0030] In technical solution seven, a reinforcement section with a higher density of grip units is formed in the metatarsal body region, near the inner foot side, compared to other parts. This reinforcement section is located at a key position for transmitting force from the metatarsal head region of the sole to other areas on the rear side. Furthermore, due to the bending of the athlete's forefoot, this area experiences relatively greater pressure and uneven force distribution. By increasing the density of grip units in this area, not only can the grip be strengthened, preventing slippage or affecting the force exertion due to insufficient grip on the inner foot side, but the strength of the sole in this area can also be enhanced, improving the rolling and rebound effect of the sole on the athlete's foot.

[0031] In technical solution eight, in the cuneiform region, the density of each gripping unit increases and then decreases from the inner foot side to the outer foot side of the body, forming a strip-shaped area with higher structural strength in the middle position. This strip-shaped area can effectively transfer the force from the metatarsal head region and the metatarsal body region to the calcaneal region, ensuring a smooth transition and effective force exertion of the athlete's foot in this area.

[0032] In technical solution nine, the density of each grip unit in the calcaneal region is relatively uniform, enabling the sole to provide stable and balanced support in the calcaneal region, allowing the athlete's heel to make smooth contact with the ground and transfer power during landing and push-off.

[0033] In technical solution ten, the density of grip units in the cuneiform and calcaneal regions is lower than that in the metatarsal head and metatarsal body regions. This is because the metatarsal head and metatarsal body regions are the main force exertion areas for athletes during sprinting, requiring stronger and denser grip to meet the needs of rapid start and acceleration. In contrast, the cuneiform and calcaneal regions mainly focus on stability and support. The relatively lower density ensures basic grip while avoiding unnecessary weight increase, making the overall performance of the sole more suitable for the characteristics of sprinting, optimizing the functional distribution of each region, and improving the overall running performance.

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

[0035] In technical solution twelve, multiple spikes are arranged along the edge of the metatarsal head area, which enables the spikes and the grip units in the metatarsal head area to work together to enhance grip performance during the start and acceleration phases.

[0036] In technical solution thirteen, the main body is equipped with a spike holder for fixing the spikes. The grip component makes way for the spike holder and is connected to the spike holder 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 reasonable cooperation between the grip component and the spike holder, realizing the compactness and integrity of the sole structure, avoiding mutual interference between the components, and ensuring that the grip component and the spikes can fully play their respective roles in improving grip.

[0037] Technical solution fourteen provides a spiked shoe that, by applying a sole with excellent grip performance to the overall structure of the spiked shoe, enables the spiked shoe to comprehensively utilize the advantages of various aspects of the sole, meet the high grip requirements of sprinters throughout the sprint, help athletes perform better, reduce the risk of sports injuries caused by insufficient grip, and is more adaptable to the characteristics of sprint events and improve athletes' athletic performance compared to existing simple spiked shoes.

[0052] Example

[0053] This utility model relates to a spiked shoe, which includes a sole suitable for sprinting provided by this utility model, and a shoe body. The bottom of the shoe body is connected to the top side surface of the sole. The shoe body used here is a conventional spiked shoe body, which forms a cavity for accommodating the athlete's foot and has a tightening structure such as laces to prevent the foot from slipping out of the spiked shoe by tightening the shoe body. The connection between the sole and the shoe body can be achieved by adhesive bonding; the adhesive materials and processes used will not be described in detail here.

[0054] The structure of a shoe sole suitable for sprinting, as described in this embodiment, is referenced. Figure 1 and Figure 2 The sole includes a body 10 and several cleats. The body 10 may be made of high-strength nylon material, and the cleats may be made of metal, such as steel. The cleats are fixedly mounted on the body 10 and protrude towards the bottom side of the body 10. The cleats may be non-removably fixed to the body 10 or detachably mounted on the body 10. The shape, structure, and assembly method of the cleats are conventional techniques in the art and will not be described in detail here.

[0055] Reference Figure 1 and Figure 2 The body 10 includes a base 11 and a gripping assembly 12. The base 11 is designed as a ring with a hollow center, according to the shape of the sole, and is located on the outer 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 and interconnected in the extension direction of the body 10. 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 that protrudes towards the bottom side of the body 10 and is cone-shaped. The included angles between each pair of the second arm 132 and the third arm 133 are obtuse angles; the gripping unit 13 is provided with a first connecting part 135, a second connecting part 136 and a third connecting part 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. The first arm 131, the second arm 132 and the third arm 133 in each gripping unit 13 are respectively connected to the second connecting part 136, the third connecting part 137 and the first connecting part 135 in the adjacent gripping unit 13, and a hollow hole 14 formed by the first arm 131, the second arm 132 and the third arm 133 is formed between the adjacent gripping units 13.

[0056] Specifically, first refer to Figure 1 andFigure 2 The body 10 includes a base 11 and a gripping component 12. The base 11 is a ring-shaped structure, with its outer periphery shaped according to the desired sole shape and extending inwards to form a hollow in the middle portion. The gripping component 12 includes several gripping units 13, which are arranged and interconnected in the extension direction of the body 10. The shape of the outer edge of the gripping component 12 is adapted to the shape of the base 11, and the outermost gripping units 13 of the gripping component 12 are connected to the bottom surface of the base 11, thus connecting the gripping component 12 and the base 11. In practical applications, the base 11 and the gripping component 12 can be molded together.

[0057] The structure of the grip unit 13 in the grip assembly 12 is referenced. Figure 3 and Figure 4 Each grip unit 13 is provided with a first arm 131, a second arm 132, and a third arm 133. The extension of the first arm 131, second arm 132, and third arm 133 forms an open structure for the grip unit 13. Each of the first arm 131, second arm 132, and third arm 133 has its own extension direction, and the included angles between any two arms are obtuse angles. This gives each grip unit 13 good structural strength in multiple directions. The first arm 131, second arm 132, and third arm 133 connect at the middle of the grip unit 13, forming a grip protrusion 134 protruding towards the bottom side of the body 10. The grip protrusion 134 is cone-shaped and can embed into the ground when the sole contacts the ground to improve 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. (Refer to...) Figure 4Taking the middle gripping unit 13 as an example, a gripping unit 13 is provided at the upper left, upper right, lower left, lower right, above, and below the middle gripping unit 13. The end of the third arm 133 of the upper left gripping unit 13 is connected to the first connecting part 135 of the gripping unit 13. The end of the second arm 132 of the upper right gripping unit 13 is connected to the third connecting part 137 of the gripping unit 13. The end of the first arm 131 of the lower gripping unit 13 is connected to the second connecting part 136 of the gripping unit 13. The end of 31 is connected to the second connecting part 136 of the gripping unit 13 above it. The end of the second arm 132 of the gripping unit 13 is connected to the third connecting part 137 of the gripping unit 13 to its lower left. The end of the third arm 133 of the gripping unit 13 is connected to the first connecting part 135 of the gripping unit 13 to its lower right. Meanwhile, a hollow hole 14 is formed between the three adjacent gripping units 13 by the first arm 131 of one gripping unit 13, the second arm 132 of another gripping unit 13, and the third arm 133 of the third gripping unit 13. Similarly, the first arm 131, the second arm 132, and the third arm 133 of each gripping unit 13 are connected to the second connecting portion 136, the third connecting portion 137, and the first connecting portion 135 of three other adjacent gripping units 13. Simultaneously, the first connecting portion 135, the second connecting portion 136, and the third connecting portion 137 of each gripping unit 13 are also connected to the third arm 133, the first arm 131, and the second arm 132 of three other adjacent gripping units 13. This arrangement interconnects the gripping units 13 in the gripping assembly 12 to form a mesh structure.

[0058] Continue to refer to Figure 3 and Figure 4 In the grip unit 13, the first arm 131, the second arm 132, and the third arm 133 are formed by the arm base 15 and the arm ridge 16 extending in a preset direction. The arm ridge 16 is located on the bottom side of the arm base 15 and has a ridge 161 protruding toward the bottom side of the body 10. The ridge 161 extends along the extension direction of the arm ridge 16. The thickness of the arm ridge 16 increases as it approaches the grip protrusion 134, so that the grip unit 13 forms a triangular pyramid-shaped grip protrusion 134 at the middle position by the arm ridges 16 of the first arm 131, the second arm 132, and the third arm 133 connecting together.

[0059] Specifically, the support arm base 15 can be considered as the base portion on the first support arm 131, the second support arm 132, and the third support arm 133. It has a certain thickness and can be considered as having a structure that extends approximately in a plane. The support arm ridge 16 can be considered as the part connected to the support arm base 15 and located on the bottom side of the support arm base 15. In fact, the gripping unit 13 is integrally formed and is not divided into two different components in the actual structure. Among them, the support arm ridge 16 is a protruding structure on the support arm base 15. It extends from the free end of the support arm base 15 toward the middle position of the gripping unit 13 and gradually thickens. At the same time, the support arm ridge 16 forms a ridge 161 similar to a mountain ridge. The two sides of the ridge 161 are inclined slopes, thus 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 grip unit 13, and the three ridges 161 cooperate to form a triangular pyramid-shaped grip protrusion 134. The end of the grip protrusion 134 is the point where the three ridges 161 overlap. The support arm in the grip unit 13 is formed by the support arm base 15 and the support arm ridge 16. The support arm base 15, as the foundation of the support arm, can provide good structural strength. The support arm ridge 16 has a ridge 161 formed on it. 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 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 support arms, thereby further enhancing the structural strength of the grip protrusion 134. This can further reduce the deformation of the grip protrusion 134 under force, allowing the grip protrusion 134 to better embed into the ground and improve the grip of the sole with the ground.

[0060] As one aspect of the sprint shoe sole involved in this embodiment, among the adjacent grip units 13 in the front-rear direction of the body 10, the extension direction of the first arm 131 of the rear grip unit 13 tends 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 generally has an extension tendency that is adapted to the extension shape of the body 10 in the length direction.

[0061] Specifically, refer to Figure 3 As can be seen in the gripping assembly 12, the first arm 131 extends approximately along the front-rear direction of the body 10, and the extension direction of the first arm 131 of each gripping unit 13 corresponds to the position of the second connecting portion 136 on that gripping unit 13. Therefore, when the first arm 131 of the next gripping unit 13 connects to the second connecting portion 136 of the previous gripping unit 13, the first arms 131 of these two gripping units 13 tend to form the extension direction of these two gripping units 13. Of course, the other second arms 132 and third arms 133 can also form a similar extension trend, but referring to...Figure 1 and Figure 2 In the sole of this embodiment, the arrangement of the gripping units 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, and its inner foot side 31 and outer foot side 32 are bent to different degrees and in different directions in the front-back direction, 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 adapted to 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 component 12 creates a continuous and adaptable grip layout along the length of the sole, which better matches the athlete's footwork sequence and movement trajectory from back to front during running. This ensures continuous, stable and effective grip during each step, avoiding slippage caused by discontinuous grip or uneven force, and helps athletes accelerate smoothly and maintain high-speed running.

[0062] Among them, reference Figure 2 The body 10 corresponds to the distribution of human foot bones from front to back as the metatarsal head region 21, metatarsal body region 22, cuneiform region 23, and calcaneus region 24. It should be understood that the above division of different regions on the body 10 is only a rough division based on the distribution of human foot bones; there are no strict boundaries between adjacent regions. Those skilled in the art can understand the approximate extent of each region and thus implement 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 gripping unit 13, the gripping unit 13 near the inner foot side 31 of the body 10 is bent in a convex shape towards the outer foot side 32 of the body 10 in the front-back direction, and the degree of bending decreases as the gripping unit 13 gets closer to the outer foot side 32 of the body 10. Furthermore, in the metatarsal head region 21, the density of each gripping unit 13 increases first and then decreases from front to back; the density of the gripping unit 13 refers to the number of gripping units 13 deployed 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 near the inner foot side 31 and outer foot side 32 of the body 10 are bent in the front-rear direction of the body 10, respectively protruding towards the inner foot side 31 and outer foot side 32 of the body 10, and the degree of bending decreases as the gripping unit 13 approaches the middle position in the left-right direction of the body 10. Furthermore, in the metatarsal body region 22, a reinforcing portion 17 with a higher density of gripping units 13 is formed near the inner foot side 31 compared to other portions.

[0065] Specifically, refer to Figure 2 In the metatarsal head region 21, multiple gripping units 13 near the inner foot side 31 of the body 10 protrude and bend towards the outer foot side 32 of the body 10, with the extension trend of the first arm 131 of the gripping unit 13 as a reference. The bending of the gripping unit 13 here is formed by the cooperation of the first arms 131 of multiple gripping units 13. Specifically, the first arm 131 of the foremost gripping unit 13 can first extend obliquely from the inner foot side 31 towards the outer foot side 32 from front to back. The oblique angle of the first arm 131 of the next gripping unit 13 after this gripping unit 13 is slightly reduced, and so on, until the oblique angle of the first arm 131 on the gripping unit 13 becomes that it extends from the inner foot side 31 towards the outer foot side 32 from front to back. During the bending process, the first arm 131 of each grip unit 13 can be slightly bent, or the position of the second connecting part 136 connecting the first arm 131 of each grip unit 13 to the previous grip unit 13 can be slightly offset from the first arm 131 of that grip unit 13. The metatarsal head region 21 is the main area of ​​contact between the athlete and the ground when running. Therefore, the grip unit 13 in the metatarsal head region 21 has a bent structure, which allows the sole to adapt to the rolling motion and force exertion of the athlete's foot in this area. The change in the degree of bending adapts to the force difference of different positions of the metatarsal head region 21 during the athlete's foot running, which allows the grip unit 13 to better fit the ground and makes the grip force more even and effective in this key foot force exertion area.

[0066] Similarly, the arrangement of the gripping units 13 in the metatarsal body region 22 and the cuneiform region 23 can be the same as that in the metatarsal head region 21, and will not be elaborated further here. The gripping units 13 in the metatarsal body region 22 have 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 of the foot in different positions. Whether it is the force exerted on the inner and outer sides of the foot or the transition movement in this area, it can get good grip support.

[0067] Furthermore, in the metatarsal head region 21, the density of the gripping units 13 exhibits a trend of increasing and then decreasing from front to back. That is, the density of gripping units 13 is low in the front and rear parts of the metatarsal head region 21, and high in the middle part. During an athlete's running, the middle position of the metatarsal head region 21 in the front-back direction is the area that is in more contact with the ground. Increasing the density of gripping units 13 in this part of the region allows the gripping protrusions 134 to be more densely packed in this area, thereby providing stronger grip. At the same time, the density of gripping protrusions 134 can be slightly reduced in the parts outside this part of the region, thereby reducing the weight of the metatarsal head region 21 body 10.

[0068] Meanwhile, in the metatarsal body region 22, a reinforced section 17 with increased density of grip units 13 is provided near the inner foot side 31. The density of grip units 13 decreases in the area outside this reinforced section 17. This reinforced section 17 is located at a critical position for transmitting force from the metatarsal head region 21 of the sole to other areas on the rear side. In this area, due to the bending of the athlete's forefoot, the foot will bear relatively greater pressure and uneven force distribution. By increasing the density of grip units 13 in this area, not only can the grip be strengthened, preventing slippage or affecting the force exertion due to insufficient grip on the inner foot side 31, but the strength of the sole in this area can also be enhanced, improving the rolling and rebound effect of the sole on the athlete's foot.

[0069] Furthermore, in the cuneiform region 23, the density of each gripping unit 13 increases and then decreases from the inner foot side 31 to the outer foot side 32 of the body 10. This creates a strip-shaped region with higher structural strength in the middle position, which can effectively transfer the force from the metatarsal head region 21 and the metatarsal body region 22 to the calcaneal region 24, ensuring a smooth transition and effective force application for the athlete's foot in this area.

[0070] Furthermore, in the heel region 24, the density of each of the gripping units 13 is relatively uniform, so that the sole can provide stable and balanced support in the heel region 24, allowing the athlete's heel to make smooth contact with the ground and transmit force during landing and pushing off.

[0071] Furthermore, the density of grip units 13 in the cuneiform region 23 and calcaneal region 24 is lower than that in the metatarsal head region 21 and metatarsal body region 22. Since the metatarsal head region 21 and metatarsal body region 22 are the main power-generating areas for athletes during sprinting, they require stronger and denser grip to meet the demands of rapid start and acceleration. In contrast, the cuneiform region 23 and calcaneal region 24 primarily focus on stable support, and their relatively lower density ensures basic grip while avoiding unnecessary weight increase. This makes the overall performance of the sole more suitable for the characteristics of sprinting, optimizes the functional distribution of each region, and improves overall running performance.

[0072] Furthermore, the sharpness of the grip protrusions 134 of the gripping unit 13 in the wedge region 23 and the calcaneal region 24 is less than that of the gripping protrusions 134 of the gripping unit 13 in the metatarsal head region 21 and the metatarsal body region 22. Here, sharpness can be considered as the trend of the angle change of the three ridges 161 relative to the extension direction of the sole, starting from the end of the grip protrusion 134. A larger angle change trend indicates greater sharpness, and a smaller angle change trend indicates less sharpness. A sharper grip protrusion 134 provides better grip embedding, thereby enabling rapid force application and acceleration. The wedge region 23 and the calcaneal region 24 mainly provide stable support, while the relatively blunt grip protrusions 134 are sufficient to ensure stable contact with the ground.

[0073] Reference Figure 2 Multiple spikes are arranged along the edge of the metatarsal head region 21. The body 10 also includes spike seats 18, which are connected to the base 11 or the grip assembly 12 and are used to fix the spikes. The grip assembly 12 makes way for the spike seats 18 at the location where the spike seats 18 are located on the body 10, and is connected to the spike seats 18 through the first arm 131, the second arm 132, and / or the third arm 133 of the grip unit 13. In this embodiment, there are seven spikes, three located on the inner foot side 31, three on the outer foot side 32, and one in the middle position. The spike in the middle position is approximately at the junction of the metatarsal head region 21 and the metatarsal body region 22. By setting the spikes, the spikes and the grip unit 13 of the metatarsal head region 21 can work together to enhance the grip performance during the start and acceleration phases. Meanwhile, a spike holder 18 is provided on the main body 10 to ensure that the spikes can be firmly installed on the sole, and to make reasonable cooperation between the grip component 12 and the spike holder 18, thereby achieving the compactness and integrity of the sole structure, avoiding mutual interference between the components, and ensuring that the grip component 12 and the spikes can fully play their respective roles in improving grip.

[0074] The present invention relates to a sprint shoe sole suitable for short-distance running, comprising a body 10 and a plurality of spikes. The spikes are disposed on the body 10 and protrude toward the bottom side of the body 10, thereby providing the sole with basic grip. Simultaneously, in cooperation with the spikes, the body 10 includes a base 11 and a grip component 12. The base 11 serves as a stable foundation for the grip component 12. The base 11 is designed as a ring with a hollow center, according to the shape of the sole, so that the empty space in the center of the base 11 can be used to house the grip component 12. This structure of the base 11 can initially reduce the weight of the body 10. The grip component 12 is formed by multiple grip units 13 arranged and interconnected in the extension direction of the body 10. The extension direction of 0 can be considered as the direction in which the sole unfolds, and the sole has a roughly flat structure. In each grip unit 13, a first arm 131, a second arm 132, and a third arm 133 are provided. These arms connect at 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. The grip protrusions 134 can embed into the ground when the sole contacts the ground, thereby increasing the grip force between the sole and the ground. Furthermore, each grip unit 13's grip protrusion 134 is formed by three arms connected together. These three arms not only effectively improve the structural stability of the grip protrusion 134 and reduce the deformation of the grip protrusion 134 under stress, but also... When the 134 grip unit embeds itself into the ground, it can cooperate with other adjacent grip units 13 to form a mesh-like force transmission structure, thereby transferring the interaction force between the contact points between the sole and the ground to the entire sole, allowing the athlete to generate more power. The angle between the arms of each grip unit 13 is obtuse, which allows each grip unit 13 to better withstand forces in different directions, effectively handling forward force during the start and lateral forces during running. Simultaneously, this structure, through the interconnection of the grip units 13, reduces the weight of the sole while effectively improving the overall structural strength and rigidity of the sole, preventing damage during running. During running, the sole of the shoe may be excessively bent. In addition, the grip units 13 are interconnected through the first, second, and third connecting parts, forming a perforated hole 14. On the one hand, the connecting parts ensure the integrity between the grip units 13, so that the entire grip assembly 12 works together to improve the overall grip effect. On the other hand, the perforated hole 14 can reduce the weight of the sole without affecting the grip, which meets the requirements of sprinting for lightweight shoes and helps athletes swing their feet more flexibly during running, reducing energy loss. Therefore, the sole with the above structure can provide athletes with good ground grip and better meet the grip needs of sprinters when they need to accelerate in a very short time and maintain high speed.

[0075] The spikes described in this utility model, by incorporating a sole with excellent grip into the overall structure of the spikes, allow the spikes to comprehensively leverage the advantages of the sole, meeting the high grip requirements of sprinters throughout the sprint process. This helps athletes perform better, reduces the risk of sports injuries caused by insufficient grip, and is more adaptable to the characteristics of sprint events compared to existing simple spikes, thus improving athletes' athletic performance.

[0076] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this utility model, but does not constitute a limitation on the scope of protection of this utility model. Modifications, equivalent substitutions, or other improvements to the embodiments of this utility model or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this utility model or the foregoing embodiments, should all be included within the scope of protection of this utility model.
