Abstract
Description
Technical Field
[0001] This utility model relates to the field of spiked shoe technology, specifically to a sole and spiked shoe suitable for middle and long-distance running. Background Technology
[0002] In middle- and long-distance running, runners maintain a relatively steady pace, with consistent stride length and cadence to conserve energy. Their posture is also relatively upright, allowing for stable center of gravity shifts. Because middle- and long-distance running is time-consuming, runners' feet are repeatedly subjected to impacts from the ground. Therefore, running shoes suitable for this event typically use materials with good cushioning in the sole to reduce the impact on the feet and minimize damage to the feet, joints, and leg muscles. To ensure good grip, the sole usually employs a composite structure of outsole and midsole. The outsole is made of durable and structurally strong materials like nylon, while the midsole uses materials with good cushioning properties. This combination provides both good cushioning and grip. However, in practical use, due to the relatively hard outsole material, runners can still experience significant impact upon landing, resulting in less effective cushioning. Utility Model Content

[0015] In addition, this utility model also provides technical solution eleven: a spiked shoe, which includes a sole suitable for middle and long-distance running as described in any one of technical solutions one to ten, characterized in that it also includes a shoe body, the bottom of which is connected to the top side surface of the sole.
[0016] 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:
[0017] Technical solution one provides a shoe sole suitable for middle and long distance running. The shoe sole includes a cushioning component, a traction component, and several spikes. The spikes are set on the traction component and protrude toward the bottom side of the shoe sole, so that the shoe sole can maintain a certain grip.
[0018] The cushioning component is designed according to the shape of the shoe sole and is adapted to provide cushioning performance. It can be made of conventional cushioning materials, such as EVA foam. The traction component includes a forefoot traction component and a rearfoot traction component, and the structural strength of the traction component is higher than that of the cushioning component. It can be made of conventional high-strength materials, such as nylon, and is used to provide good grip for the shoe sole when it contacts the ground. The cushioning component has a forefoot mounting section, a traction section, and a rearfoot mounting section. The forefoot traction component and the rearfoot traction component are respectively fixed to the forefoot mounting section and the rearfoot mounting section. On the mounting section, after the traction component is fixed to the cushioning component, the bottom surfaces of the two are flush at the joint; at the same time, the traction part is higher than the front mounting part. This arrangement creates a structure on the bottom surface of the sole where the traction component and the cushioning component are arranged alternately. When the bottom surface of the sole touches the ground, both the traction component and the cushioning component will contact the ground. Since the cushioning component is in direct contact with the ground, the impact of the hard outsole on the cushioning performance of the sole is effectively reduced. At the same time, the harder traction component is also in contact with the ground, so that the sole still has good traction and wear resistance.
[0019] Furthermore, a first protrusion is provided on the gripping part, and a second and third protrusion are respectively provided on the forefoot and rearfoot gripping components. The first and second protrusions are mainly distributed in the forefoot area of the sole. When a runner runs, it is mainly the forefoot area that contacts the ground and provides grip to propel the runner forward. The first and second protrusions added to the forefoot area can embed into the ground when the sole hits the ground, thereby improving the grip performance of the sole. Moreover, due to the different materials of the forefoot gripping component and the cushioning component, the deformation of the first and second protrusions upon contact with the ground is also different. The first protrusion is softer and therefore has a stronger grip. Large deformation occurs because the gripping part is located between the first and second extension arms of the forefoot gripping component. Therefore, the first and second protrusions can cooperate with each other. When the sole hits the ground, the second protrusion is firmly embedded in the ground, while the first protrusion can deform slightly to increase the contact area between the sole and the ground. At the same time, the protruding structure of the first protrusion can transmit the impact force of the ground to the entire cushioning component, thereby quickly allowing the cushioning component to absorb the impact force of the ground. The third protrusion on the rear gripping component can effectively improve the stability of the runner's heel when hitting the ground during middle and long-distance running, and improve the anti-slip performance of the heel area.
[0020] Meanwhile, the forefoot grip component is designed as a bent shape formed by the connection of the first and second extension arms, and the gripping part is located between the first and second extension arms of the forefoot grip component. This design enhances the structural strength of the sole along the inner and outer edges of the foot, thereby providing better support for the foot on the inner and outer sides of the foot. Furthermore, due to the shape characteristics of the forefoot grip component, the first and second extension arms bend when the sole hits the ground. The space between the first and second extension arms allows for better bending and rebound performance of the forefoot grip component, preventing the forefoot area from being too hard to bend and resulting in excessive impact on the foot when the sole hits the ground.
[0021] Therefore, the sole with the above structure can provide runners with good ground grip and better cushioning performance, better meeting the running needs of middle and long-distance runners.
[0022] In technical solution two, the cushioning component includes an upper cushioning component and a lower cushioning component, with a reinforcing component fixedly installed between them. The reinforcing component extends in the fore-and-aft direction. When the sole bends upon contact with the ground, the reinforcing component bends accordingly and accumulates energy. Then, when the runner pushes off the ground, it recovers its deformation and releases energy, thereby providing a propulsive effect on the foot during the rolling motion of the sole. This can effectively improve the runner's athletic performance. At the same time, the reinforcing component can effectively improve the overall structural strength of the sole in the fore-and-aft direction without affecting the cushioning effect of the cushioning component. This can prevent excessive bending and deformation of the sole, thereby enhancing the overall structural stability of the sole.
[0023] In technical solution three, the rear end of the first extension arm of the forefoot grip component is located at the junction of the forefoot area and the arch area of the sole, and the rear end of the second extension arm is located in the arch area of the sole. That is, the rear end of the second extension arm is closer to the rear end of the sole than the rear end of the first extension arm. The forefoot grip component presents a bent shape with inconsistent heights at both ends. This design allows the bend of the forefoot grip component to adapt to the shape of the human foot, further enhancing the support effect on the human foot on the outer side.
[0024] In technical solution four, the front end of the grip unit extends to the middle of the forefoot area of the sole, and the rear end extends to the arch area of the sole. This reasonably expands the distribution range of the grip unit on the sole, allowing it to better exert its grip during running, especially during forefoot strike and transition to arch support.
[0025] In technical solution five, the gripping part has several first perforations that run through the lower cushioning component along the thickness direction, and are arranged in a row and column layout at intervals in a way that is inclined relative to the length of the sole. These first perforations can reduce the weight of the sole, which helps runners save energy and improve athletic performance for middle and long-distance running. On the other hand, without affecting the overall structural strength and grip and cushioning functions, the setting of the first perforations enhances the deformation capacity of the sole, allowing the runner's foot to move more naturally and adapt to changes in the ground during running.
[0026] In technical solution six, the first protrusion and the first hollow hole are staggered. This arrangement can reduce the impact of the first protrusion on the deformation enhancement ability of the first hollow hole and avoid structural conflicts between the two. Furthermore, when the sole touches the ground, the first protrusion will embed itself into the ground after contacting it, and at the same time, part of the pushed ground will sink into the first hollow hole near the first protrusion, so that the first hollow hole can also form an interaction with the ground, thereby further enhancing the grip of the sole on the ground.
[0027] In technical solution seven, a second perforation is provided on the front grip component, which can further reduce the weight of the front grip component; at the same time, after the second protrusion contacts the ground, it will embed into the ground, and part of the ground that is pushed will sink into the second perforation near the second protrusion, so that the second perforation can also form an interaction with the ground, thereby further enhancing the grip of the sole on the ground.
[0028] In technical solution eight, the density of the first protrusion in the grip part increases towards the rear. Since the front end of the grip part is located in the middle of the forefoot area, and the forefoot area of the sole is the main contact area with the ground when the runner is running, increasing the density of the first protrusion in this part of the grip part can make the grip performance of this part stronger. The density of the first protrusion on the rear side can be appropriately reduced so that the sole can have better deformation ability.
[0029] In technical solution nine, the density of the first protrusion in the front grip component first increases and then decreases. That is, the density of the first protrusion in the front part of the front grip component is small, the density of the first protrusion in the middle part is large, and the density of the first protrusion in the rear part decreases again. This setting can make the grip performance of the middle part of the front grip component stronger, while the rear part near the arch area has better bending and deformation capabilities.
[0030] In technical solution ten, the upper cushioning component is provided with a limiting protrusion, and the lower cushioning component is provided with a limiting groove. The limiting protrusion can be embedded into the limiting groove when the lower cushioning component and the upper cushioning component are in contact, so that the lower cushioning component and the upper cushioning component form a limiting engagement in the forward direction. When the runner is running, the lower cushioning component contacts the ground and will be subjected to a forward reaction force. The limiting protrusion restricts the relative displacement between the lower cushioning component and the upper cushioning component, which can prevent the lower cushioning component from detaching from the upper cushioning component.
[0031] Technical solution eleven provides a spiked shoe, which includes the aforementioned sole and upper suitable for middle and long-distance running. The bottom is connected to the top side surface of the sole. The application of a high-performance sole to the spiked shoe product gives the entire spiked shoe the advantage of a good balance between grip and cushioning provided by the sole. It can provide middle and long-distance runners with a comfortable, safe and reliable wearing experience, meeting the professional requirements of middle and long-distance running for footwear.

[0050] Example
[0051] This utility model relates to a spiked shoe, which includes a sole suitable for middle- and long-distance running as provided by this utility model, and also includes 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 are not detailed here.
[0052] The structure of the shoe sole suitable for middle- and long-distance running involved in this embodiment of the utility model is as follows: Figure 1 The sole includes a cushioning component 10, a traction component 20, a reinforcement component 40, and several spikes 30. The cushioning component 10 can be made of a material with cushioning properties, such as EVA foam; the traction component 20 can be made of a high-strength material, such as nylon; the reinforcement component 40 can be made of nylon or carbon fiber; and the spikes 30 can be made of metal materials such as steel.
[0053] Reference Figure 2 This is a schematic diagram of the assembly state of the shoe sole, and also refers to... Figure 3 , Figure 3 The document indicates that the sole corresponds to the human foot structure from front to back as the forefoot region 51, the arch region 52, and the heel region 53. It should be noted that the above division of the different regions of the sole is only a rough division based on the skeletal distribution of the human foot; 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 sole structure involved in this embodiment.
[0054] Reference Figure 1 and Figure 2In the shoe sole of this embodiment, the cushioning component 10 is configured according to the shape of the shoe sole and adapted to give the shoe sole cushioning performance. Its bottom side surface is provided with a forefoot mounting portion 11, a gripping portion 12, and a rear mounting portion 13. The forefoot mounting portion 11 is recessed into the forefoot region 51 and the arch region 52 of the shoe sole, and is provided with a first extension portion 111 located on the inner foot side 61 of the shoe sole and a second extension portion 112 located on the inner foot side 61 of the shoe sole. The first extension portion 111 and the second extension portion 112 are located at the front end of the shoe sole. The front mounting portion 11 is connected to the rear mounting portion 13, which is bent to fit the shape of the outer periphery of the sole. The rear mounting portion 13 is recessed in the heel area 53 of the sole, and the shape of its outer periphery fits the shape of the outer periphery of the heel area 53 of the sole. The grip portion 12 is higher than the front mounting portion 11 and is located between the first extension portion 111 and the second extension portion 112 of the front mounting portion 11 in the left-right direction of the sole. It is provided with a plurality of first protrusions 121 protruding toward the bottom side of the sole. The traction component 20 includes a front traction member 21 and a rear traction member 22, and its structural strength is higher than that of the cushioning component 10. The front traction member 21 is adapted to the shape of the front mounting portion 11 and is provided with a first extension arm and a second extension arm corresponding to the first extension portion 111 and the second extension portion 112, respectively, and is fixed to the front mounting portion 11. It also has a plurality of second protrusions 211 protruding towards the bottom side of the sole. The rear traction member 22 is adapted to the shape of the rear mounting portion 13 and is suitable for being fixed to the rear mounting portion 13. It also has a third protrusion 221 protruding towards the bottom side of the sole. The cleat 30 is fixedly mounted on the front traction member 21 of the traction component 20 and protrudes towards the bottom side of the sole. After the traction component 20 is fixed to the cushioning component 10, the bottom surfaces of the two are flush at the joint.
[0055] The cushioning assembly 10 includes an upper cushioning member 14 and a lower cushioning member 15 connected to each other; the bottom side surface of the lower cushioning member 15 is provided with the front mounting part 11, the gripping part 12 and the rear mounting part 13; the upper cushioning member 14 is fixed to the top side surface of the lower cushioning member 15; the reinforcing member 40 is fixedly installed between the upper cushioning member 14 and the lower cushioning member 15, and extends from the forefoot area 51 of the sole to the heel area 53, and its bending strength in the front-back direction is higher than that of the cushioning assembly 10.
[0056] Specifically, refer to Figure 1The cushioning component 10 includes an upper cushioning element 14 and a lower cushioning element 15. The bottom surface of the upper cushioning element 14 is in contact with the top surface of the lower cushioning element 15, and the connection method can be adhesive or other suitable methods. The cushioning component 10 formed by the combination of the upper cushioning element 14 and the lower cushioning element 15 has a conventional sole shape, wherein the thickness of the upper cushioning element 14 is greater than the thickness of the lower cushioning element 15, and the upper cushioning element 14 plays the main cushioning role in the cushioning component 10.
[0057] A mounting groove 142 is recessed on the bottom surface of the upper damping member 14. The shape of the outer periphery of the mounting groove 142 matches the shape of the outer periphery of the upper damping member 14, and its shape and size match the shape and size of the reinforcing member 40. The depth of the mounting groove 142 also matches the thickness of the reinforcing member 40. The reinforcing member 40 can be installed in the mounting groove 142 and fixed inside the damping assembly 10 through the engagement between the lower damping member 15 and the upper damping member 14. The reinforcing member 40 can be made of nylon or carbon fiber, which has high structural strength and can accumulate potential energy and recover its deformation after bending. When the sole bends upon contact with the ground, the reinforcement 40 bends accordingly and stores energy. Then, when the runner pushes off the ground, it recovers its deformation and releases the energy, thus providing a boost to the foot during the rolling motion of the sole. This effectively improves the runner's athletic performance. At the same time, the reinforcement 40 can effectively improve the overall structural strength of the sole in the forefoot and hindfoot directions without affecting the cushioning effect of the cushioning component 10. This can prevent excessive bending and deformation of the sole, thereby enhancing the overall structural stability of the sole.
[0058] Furthermore, the bottom surface of the upper cushioning member 14 has a limiting protrusion 141 protruding at its front end, and the lower cushioning member 15 has a limiting groove at its front end that matches the limiting protrusion 141. After the upper cushioning member 14 and the lower cushioning member 15 are in contact, the limiting protrusion 141 is embedded in the limiting groove. This arrangement allows the lower cushioning member 15 to form a limiting engagement with the upper cushioning member 14 in the forward direction. When a runner is running, the lower cushioning member 15 contacts the ground and receives a forward reaction force. The limiting protrusion 141 restricts the relative displacement between the lower cushioning member 15 and the upper cushioning member 14, thus preventing the lower cushioning member 15 from detaching from the upper cushioning member 14.
[0059] The bottom surface of the lower shock absorber 15 is provided with the aforementioned front mounting portion 11, gripping portion 12, and rear mounting portion 13. (Refer to...) Figure 5The front mounting portion 11 has a first extension 111 and a second extension 112, both extending along the length of the sole and meeting at the front end of the lower cushioning member 15, thus forming a bent structure protruding towards the front end of the sole. In this embodiment, the first extension 111 and the second extension 112 are respectively located near the inner foot side 61 and the outer foot side 62 of the sole, and their outer edges meet the side edges of the sole, while their inner edges extend inward by a certain distance, thus forming a structure surrounding the forefoot area 51 of the lower cushioning member 15. The front mounting portion 11 also has several clearance holes 113, which are used to allow space for the cleats 30 when the traction assembly 20 is fitted with cleats 30.
[0060] Continue to refer to Figure 5 The lower cushioning member 15 has a gripping portion 12 in the portion between the first extension 111 and the second extension 112 of the front mounting portion 11. The front end of the gripping portion 12 extends to the middle of the forefoot area 51 of the sole, and its rear end extends to the arch area 52 of the sole. The gripping portion 12 also has a plurality of first perforated holes 122 penetrating the lower cushioning member 15 along the thickness direction. These first perforated holes 122 are arranged in multiple groups at intervals with an oblique arrangement relative to the length direction of the sole, forming a row and column layout. Among them, some of the first protrusions 121 are located between adjacent first perforated holes 122 and are offset from the first perforated holes 122 in the row and column direction to form a row and column layout similar to the first perforated holes 122. Furthermore, in the gripping portion 12, the arrangement density of each first protrusion 121 has a tendency to gradually increase with the position; the arrangement density of the first protrusions 121 refers to the number of first protrusions 121 arranged per unit area.
[0061] Specifically, refer to Figure 1The gripping portion 12 is higher than the front mounting portion 11. "Higher" here means that, based on the bottom surface of the front mounting portion 11, the bottom surface of the gripping portion 12 protrudes beyond the bottom surface of the front mounting portion 11. The shape of the outer periphery of the gripping portion 12 matches the shape of the inner edge of the front mounting portion 11, which can be considered as the gripping portion 12 being embedded between the first extension 111 and the second extension 112 of the front mounting portion 11 in the front-rear direction. A plurality of first protrusions 121 protrude from the gripping portion 12. In this embodiment, the first protrusions 121 are pyramidal, preferably quadrangular pyramidal. In other embodiments, the first protrusions 121 may also be conical or other similar shapes. Simultaneously, a plurality of first perforated holes 122 protrude from the gripping portion 12. In this embodiment, the first perforated holes 122 are quadrilateral. The front end of the gripping section 12 extends to the middle of the forefoot area 51 of the sole, and the rear end extends to the arch area 52 of the sole. This reasonably expands the distribution range of the gripping section 12 on the sole, allowing it to better exert its gripping effect during running, especially during forefoot strike and the transition to arch support. The first perforation 122 reduces the weight of the sole, which helps runners conserve energy and improve athletic performance, especially for middle- and long-distance running. Furthermore, without compromising the overall structural strength and grip / cushioning functions, the first perforation 122 enhances the sole's deformability, allowing the runner's foot to move more naturally and adapt to changes in the ground during running.
[0062] The first perforated hole 122 and the first protrusion 121 in the gripping part 12 are both designed in a row-and-column layout. (Refer to...) Figure 5The location of the first perforated holes 122 belonging to the same column or row is indicated by dashed lines. The first perforated holes 122 belonging to the same column are represented by a dashed line extending from the inner foot side 61 towards the outer foot side 62 from front to back, and the first perforated holes 122 belonging to the same row are represented by a dashed line extending from the outer foot side 62 towards the inner foot side 61 from front to back. With this arrangement, the layout of the first perforated holes 122 can be considered as extending obliquely relative to the length direction of the sole. Similarly, the layout of the first protrusions 121 can also be considered as extending obliquely relative to the length direction of the sole. Furthermore, during the oblique extension arrangement of the first protrusions 121 and the first perforated holes 122, the extension trend of the first protrusions 121 and the second perforated holes 212 can be bent to better adapt to the shape of the outer periphery of the sole. It should be noted that the length direction referred to in this specification and claims refers to the direction that adapts to the shape of the outer periphery of the sole, while the front-to-back direction refers to the direction from the front end of the sole to its rear end. The arrangement of the first perforated hole 122 and the first protrusion 121 can reduce the influence of the first protrusion 121 on the deformation enhancement ability of the first perforated hole 122 and avoid structural conflicts between the two. Furthermore, when the sole touches the ground, the first protrusion 121 will embed into the ground after contacting the ground, and at the same time, part of the pushed ground will sink into the first perforated hole 122 near the first protrusion 121, so that the first perforated hole 122 can also form an interaction with the ground, thereby further enhancing the grip of the sole on the ground.
[0063] In addition, refer to Figure 5 The density of the first protrusion 121 in the grip part 12 increases towards the rear. Since the front end of the grip part 12 is located in the middle of the forefoot area 51, and the forefoot area 51 of the sole is the main contact area with the ground when the runner is running, increasing the density of the first protrusion 121 in this part of the grip part 12 can make the grip performance of this part stronger. The density of the first protrusion 121 in the rear part can be appropriately reduced so that the sole can have better deformation ability.
[0064] Reference Figure 1 The grip assembly 20 includes a front gripper 21 and a rear gripper 22. (See reference...) Figure 4 and Figure 5 The shape of the front grip component 21 is adapted to the shape of the front mounting portion 11 of the lower cushioning component 15. It has a first extension arm corresponding to the first extension portion 111 and a second extension arm corresponding to the second extension portion 112. The first extension arm and the second extension arm are connected at the front end of the sole, so that the shape of the front grip component 21 is a bent shape protruding towards the front end of the sole, and a bending groove 214 is formed between the first extension arm and the second extension arm. When the front grip component 21 is fixedly installed to the front mounting portion 11, the grip portion 12 can be embedded into the bending groove 214.
[0065] The bottom surface of the forefoot grip member 21 has several second protrusions 211 protruding towards the bottom side of the sole, and also has several second perforated holes 212 penetrating the forefoot grip member 21 along its thickness direction. These second perforated holes 212 are arranged at intervals with an oblique arrangement relative to the length direction of the sole. The second protrusions 211 are also generally offset from the second perforated holes 212, and the second protrusions 211 are pyramidal, preferably quadrangular pyramidal. In other embodiments, the second protrusions 211 may also be conical or other similar shapes. The second perforated holes 212 are quadrilateral in shape. In addition, the forefoot grip member 21 also has nail stations 213 in the same number as the number of cleats 30, which are used to install and fix the cleats 30. The front grip component 21 is provided with a second hollow hole 212, which can further reduce the weight of the front grip component 21; at the same time, after the second protrusion 211 contacts the ground, it will embed into the ground, and part of the ground that is pushed will sink into the second hollow hole 212 near the second protrusion 211, so that the second hollow hole 212 can also form an interaction with the ground, thereby further enhancing the grip of the sole on the ground.
[0066] Among them, reference Figure 3 and Figure 4 The rear end of the first extension arm of the forefoot grip component 21 is located at the junction of the forefoot area 51 and the arch area 52 of the sole, while the rear end of the second extension arm is located in the arch area 52 of the sole. Specifically, the rear end of the second extension arm is closer to the rear end of the sole than the rear end of the first extension arm, and the forefoot grip component 21 has a bent shape with inconsistent heights at both ends. This design allows the bend of the forefoot grip component 21 to adapt to the shape of the human foot, further enhancing the support effect on the human foot on the outer side 62.
[0067] In addition, refer to Figure 4 In the front grip component 21, the density of each of the second protrusions 211 first increases and then decreases; the density of the second protrusions 211 refers to the number of second protrusions 211 arranged per unit area. The density of the first protrusions 121 in the front grip component 21 first increases and then decreases, that is, the density of the first protrusions 121 in the front part of the front grip component 21 is small, the density of the first protrusions 121 in the middle part is large, and the density of the first protrusions 121 in the rear part decreases again. This arrangement makes the grip performance of the middle part of the front grip component 21 stronger, while the rear part near the arch area 52 has better bending and deformation capabilities.
[0068] Reference Figure 1The spike 30 includes a spike body 31 and a spike seat 32. The spike body 31 is detachably fixed in the spike seat 32, and the spike seat 32 is fixed on the spike platform 213 of the front grip member 21. Depending on the situation, spike bodies 31 of different lengths can be selected and installed in the spike seat 32 to expand the applicability of the spiked shoe.
[0069] The present invention relates to a shoe sole suitable for middle- and long-distance running, comprising a cushioning component 10, a traction component 20, and several spikes 30. The spikes 30 are disposed on the traction component 20 and protrude toward the bottom side of the sole, thereby enabling the sole to maintain a certain grip. The cushioning component 10 is designed according to the shape of the sole and is adapted to provide cushioning performance. It can be made of conventional cushioning materials, such as EVA foam. The traction component 20 includes a forefoot traction member 21 and a rearfoot traction member 22, and the structural strength of the traction component 20 is higher than that of the cushioning component 10. It can be made of conventional high-strength materials, such as nylon, and is used to provide good grip when the sole contacts the ground. The cushioning component 10 is provided with a front mounting portion. 11. The gripping section 12 and the rear mounting section 13: The front gripping component 21 and the rear gripping component 22 of the gripping assembly 20 are respectively fixed on the front mounting section 11 and the rear mounting section 13. After the gripping assembly 20 is fixed to the cushioning assembly 10, the bottom side surfaces of the two are flush at the contact point. At the same time, the gripping section 12 is higher than the front mounting section 11. This arrangement creates a structure on the bottom side surface of the sole where the gripping assembly 20 and the cushioning assembly 10 are arranged alternately. When the bottom side surface of the sole touches the ground, both the gripping assembly 20 and the cushioning assembly 10 will contact the ground. Since the cushioning assembly 10 is in direct contact with the ground, the impact of the hard outsole on the cushioning performance of the sole is effectively reduced. At the same time, the relatively hard gripping component 20 is also in contact with the ground, allowing the sole to still have good cushioning performance. The shoe improves grip and abrasion resistance. Specifically, a first protrusion 121 is provided on the gripping part 12, and a second protrusion 211 and a third protrusion 221 are respectively provided on the forefoot gripping component 21 and the rear gripping component 22. The first protrusion 121 and the second protrusion 211 are mainly distributed in the forefoot area 51 of the sole. When a runner runs, the forefoot area 51 is the primary contact point with the ground, providing grip to propel the runner forward. The first protrusion 121 and the second protrusion 211 added to the forefoot area 51 can embed into the ground when the sole contacts the ground, thereby improving the grip performance of the sole. Furthermore, due to the different materials of the forefoot gripping component 21 and the cushioning component 10, the deformation of the first protrusion 121 and the second protrusion 211 upon contact with the ground also differs. The first protrusion 121 is softer and therefore has greater deformation. Since the gripping part 12 is located between the first and second extension arms of the front gripping part 21, the first protrusion 121 and the second protrusion 211 can cooperate with each other. When the sole hits the ground, the second protrusion 211 is firmly embedded in the ground, and the first protrusion 121 can deform slightly to increase the contact area between the sole and the ground. At the same time, the protruding structure of the first protrusion 121 can transmit the impact force of the ground to the entire cushioning component 10, thereby quickly allowing the cushioning component 10 to absorb the impact force of the ground. The third protrusion 221 provided on the rear gripping part 22 can effectively improve the stability of the runner's heel when hitting the ground and improve the anti-slip performance of the heel position when the runner is engaged in middle and long-distance running.Meanwhile, the forefoot gripper 21 is configured as a bent shape formed by the connection of the first and second extension arms, and the gripping part 12 is located between the first and second extension arms of the forefoot gripper 21. This configuration enhances the structural strength of the sole along the edges of the inner foot side 61 and the outer foot side 62, thereby providing better support for the foot on the inner and outer foot sides 61 and 62. Furthermore, due to the shape characteristics of the forefoot gripper 21, the first and second extension arms bend when the sole hits the ground, and the space between the first and second extension arms allows for better bending and rebound performance of the forefoot gripper 21, preventing the forefoot area 51 from being too stiff and difficult to bend, which would result in excessive impact on the foot when the sole hits the ground. Therefore, the sole with the above structure can provide runners with good ground grip and better cushioning performance, better meeting the running needs of middle and long-distance runners.
[0070] The spikes described in this embodiment include the aforementioned sole and upper suitable for middle and long-distance running. The bottom is connected to the top side surface of the sole. By applying a high-performance sole to the spikes, the entire spike possesses the advantage of a good balance between grip and cushioning provided by the sole. This provides middle and long-distance runners with a comfortable, safe, and reliable wearing experience, meeting the professional requirements of middle and long-distance running for footwear.

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.
