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 middle and long-distance running. Background Art

[0002] In the middle and long distance running events, runners will run at a relatively stable speed, and the stride and frequency during running are relatively stable to save energy. At the same time, the body posture is relatively upright so that the center of gravity can move smoothly. Since the middle and long distance running process takes a long time, the runner's feet will be repeatedly subjected to the impact of the ground. Therefore, the existing running shoes suitable for middle and long distance running generally use materials with good shock absorption to make the soles, so as to reduce the impact of the ground on the feet and reduce the damage to the feet, joints and leg muscles. In order to make the sole have good grip, the sole generally adopts a composite structure of an outsole and a midsole. The outsole is made of materials with good wear resistance and high structural strength such as nylon, and the midsole is made of materials with good shock absorption performance. The combination of the two enables the sole to provide a good shock absorption effect for the runner's feet and ensure good grip. However, in actual applications, due to the hard material of the outsole, the sole of this structure still feels a large impact when landing, and the shock absorption effect is not good.

[0014] Technical solution ten based on technical solution two: a limiting protrusion is protruding from the bottom side surface of the upper shock-absorbing component at the front end position, and a limiting groove adapted to the limiting protrusion is provided at the front end position of the lower shock-absorbing component; after the upper shock-absorbing component is fitted with the lower shock-absorbing component, the limiting protrusion is embedded in the limiting groove.

[0015] In addition, the present invention also provides technical solution eleven: a spiked shoe, comprising 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] It can be seen from the above description of the present invention that, compared with the prior art, the present invention has the following beneficial effects:

[0017] Technical solution 1 provides a sole suitable for middle and long distance running, the sole comprising a shock absorbing component, a gripping component and a plurality of spikes, the spikes being arranged on the gripping component and protruding toward the bottom side of the sole, so that the sole can maintain a certain grip;

[0018] The shock absorbing component is arranged according to the shape of the sole and is suitable for making the sole have shock absorbing performance. It can be made of conventional materials with shock absorbing performance, such as EVA foam material, etc.; the gripping component includes a front gripping piece and a rear gripping piece, and the structural strength of the gripping component is higher than that of the shock absorbing component. It can be made of conventional materials with high structural strength, such as nylon, etc., and is used to provide good grip for the sole when the sole contacts the ground; wherein the shock absorbing component is provided with a front mounting portion, a gripping portion and a rear mounting portion, and the front gripping piece and the rear gripping piece of the gripping component are respectively fixed on the front mounting portion and the rear mounting portion The front mounting portion is mounted on the gripping component, and after the gripping component is fixed to the shock absorbing component, the bottom side surfaces of the two are flush at the joint position; at the same time, the gripping portion is higher than the front mounting portion. In this way, the bottom side surface of the sole forms a structure in which the gripping component and the shock absorbing component are arranged at intervals. When the bottom side surface of the sole touches the ground, the gripping component and the shock absorbing component will both contact the ground. Since the shock absorbing component directly contacts the ground, the influence of the hard outsole on the shock absorbing performance of the sole is effectively reduced. At the same time, the gripping component with a harder material also contacts the ground, so that the sole still has good gripping performance and wear resistance.

[0019] Among them, a first protrusion is further arranged on the gripping portion, and a second protrusion and a third protrusion are respectively arranged on the front gripping piece and the rear gripping piece, wherein the first protrusion and the second protrusion are mainly distributed in the forefoot area of ​​the sole. When the runner runs, it is mainly the forefoot area that contacts the ground and provides grip for the sole to drive the runner to move forward. The first protrusion and the second protrusion added to the forefoot area can be embedded in the ground when the sole touches the ground, thereby improving the grip performance of the sole; and due to the different materials of the front gripping piece and the shock-absorbing component, the deformation of the first protrusion and the second protrusion when touching the ground is also different, and the first protrusion is softer and therefore has a better The first protrusion and the second protrusion can cooperate with each other. When the second protrusion is firmly embedded in the ground when the sole touches the ground, the first protrusion can be slightly deformed to increase the contact area between the sole and the ground. At the same time, the impact force of the ground can be transmitted to the entire shock-absorbing component through the protruding structure of the first protrusion, so that the shock-absorbing component can quickly absorb the impact force of the ground. The third protrusion arranged on the rear gripping member can effectively improve the stability of the runner's heel when the runner is doing middle and long-distance running, and improve the anti-slip performance of the heel position.

[0020] At the same time, the front gripping member is configured to be a bent shape formed by connecting the first extension arm and the second extension arm, and the gripping portion is configured between the first extension arm and the second extension arm of the front gripping member. This configuration enhances the structural strength of the inner and outer edges of the sole, thereby enabling the sole to provide better support for the foot at the inner and outer sides. Furthermore, due to the shape characteristics of the front gripping member, when the sole bends when touching the ground, the first extension arm and the second extension arm will bend, and the empty portion between the first extension arm and the second extension arm will enable the front gripping member to have better bending and rebound performance, thereby avoiding the forefoot area being too hard to bend, thereby preventing the sole from causing excessive impact on the foot when touching the ground.

[0021] Therefore, the sole adopting the above structure can provide runners with good ground grip and better shock absorption performance, and better meet the running needs of middle- and long-distance runners.

[0022] In technical solution two, the shock-absorbing component includes an upper shock-absorbing component and a lower shock-absorbing component, and a reinforcement component is fixedly installed between the two. The reinforcement component extends in the front-to-back direction. When the sole bends when touching the ground, the reinforcement component can bend accordingly and accumulate energy, and then restore the deformation and release energy when the runner pushes off the ground, thereby boosting the foot during the rolling process of the sole touching the ground, which can effectively improve the runner's athletic performance. At the same time, the reinforcement component can effectively improve the overall structural strength of the sole in the front-to-back direction without affecting the shock-absorbing effect of the shock-absorbing component, which can avoid 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 front grip piece 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, and the front grip piece presents a bending shape with inconsistent heights at both ends; such a setting can make the bending of the front grip piece adapt to the shape of the sole of the human foot, further enhancing the supporting effect on the human foot on the outer side of the foot.

[0024] In technical solution four, the front end of the gripping part extends to the middle part of the forefoot area of ​​the sole, and the rear end extends to the arch area of ​​the sole, which reasonably expands the distribution range of the gripping part on the sole, so that it can better play the gripping role during running, especially when the forefoot touches the ground and transitions to the arch support stage.

[0025] In technical solution five, the gripping portion is provided with a plurality of first hollow holes that penetrate the lower shock-absorbing component along the thickness direction, and are arranged in a matrix layout at intervals in a manner of being inclined relative to the length direction of the sole; on the one hand, these first hollow holes can reduce the weight of the sole. For middle and long-distance running, reducing the weight of the shoe helps runners save energy and improve athletic performance; on the other hand, without affecting the overall structural strength and the gripping and shock-absorbing functions, the setting of the first hollow holes enhances the deformation ability of the sole, allowing the runner's feet to move more naturally and adapt to ground changes during running.

[0026] In technical solution six, the first protrusion and the first hollow hole are staggered with each other. Such a setting can reduce the influence of the first protrusion on the deformation enhancement ability of the first hollow hole, thereby avoiding the structural conflict between the two; and when the sole touches the ground, the first protrusion will be embedded in the ground after contacting the ground, 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 sole's grip on the ground.

[0027] In technical solution seven, a second hollow hole is provided on the front gripping piece, which can further reduce the weight of the front gripping piece; at the same time, the second protrusion will be embedded in the ground after contacting the ground, and at the same time, part of the pushed ground will sink into the second hollow hole near the second protrusion, so that the second hollow hole 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 layout density of the first protrusions in the grip portion increases toward the back. Since the front end of the grip portion 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 runs, increasing the layout density of the first protrusions of the grip portion in this area can make the grip performance of this part stronger, while the density of the first protrusions on the rear side can be appropriately reduced so that the sole can have better deformation ability.

[0029] In technical solution nine, the layout density of the first protrusions in the front grip piece first increases and then decreases, that is, the layout density of the first protrusions in the front part of the front grip piece is small, the layout density of the first protrusions in the middle part is large, and the layout density of the first protrusions in the rear part becomes smaller again. This arrangement can make the grip performance of the middle part of the front grip piece stronger, and the part on the rear side close to the arch area has better bending and deformation capabilities.

[0030] In the tenth technical solution, a limiting protrusion is provided on the upper shock-absorbing component, and a limiting groove is provided on the lower shock-absorbing component. The limiting protrusion can be embedded in the limiting groove when the lower shock-absorbing component is in contact with the upper shock-absorbing component, so that the lower shock-absorbing component forms a limiting fit with the upper shock-absorbing component in the forward direction; when the runner runs, the lower shock-absorbing component contacts the ground and will be subjected to a forward reaction force. The limiting protrusion limits the relative displacement between the lower shock-absorbing component and the upper shock-absorbing component, thereby preventing the lower shock-absorbing component from detaching from the upper shock-absorbing component.

[0031] Technical solution eleven provides a spike shoe, which includes the above-mentioned sole suitable for middle and long-distance running and a shoe body, the bottom is connected to the top side surface of the sole, and the sole with excellent performance is applied to the spike shoe product, so that the entire spike shoe has the advantage of a good balance between grip and shock absorption effect brought by the sole, and can provide middle and long-distance runners with a comfortable, safe and reliable wearing experience, and meet the professional requirements of middle and long-distance running events for shoes.

The connection between the sole and the shoe body can be achieved by bonding, and the bonding materials, processes, etc. used are not described in detail here.

[0052] The structure of the shoe sole suitable for middle and long distance running according to the embodiment of the present invention is shown in FIG.

It should be noted that the above division of different areas of the sole is only a rough division based on the bone distribution 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.

[0054] Reference Figure 1 and Figure 2In the sole involved in this embodiment, the shock absorbing component 10 is arranged according to the shape of the sole and is suitable for making the sole have shock absorbing performance, and the bottom surface thereof is provided with a front mounting portion 11, a gripping portion 12 and a rear mounting portion 13; the front mounting portion 11 is recessed in the forefoot area 51 and the arch area 52 of the sole, and is provided with a first extension portion 111 located on the inner foot side 61 of the sole and a second extension portion 112 located on the inner foot side 61 of the sole, the first extension portion 111 and the second extension portion 112 are located at the front end of the sole The front mounting portion 11 is connected to each other so that the front mounting portion 11 forms a bending shape that is adapted to the shape of the outer peripheral edge of the sole; the rear mounting portion 13 is recessed in the heel area 53 of the sole, and the shape of its outer peripheral edge is adapted to the shape of the outer peripheral edge of the heel area 53 of the sole; the gripping 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, and is provided with a plurality of first protrusions 121 protruding toward the bottom side of the sole. The gripping assembly 20 includes a front gripping member 21 and a rear gripping member 22, and its structural strength is higher than that of the shock absorbing assembly 10; the front gripping 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 fixedly mounted on the front mounting portion 11, and is provided with a plurality of second protrusions 211 protruding toward the bottom side of the sole; the shape of the rear gripping member 22 is adapted to the shape of the rear mounting portion 13 and is suitable for being fixedly mounted on the rear mounting portion 13, and is provided with a third protrusion 221 protruding downward toward the bottom side of the sole. The shoe spikes 30 are fixedly mounted on the front gripping member 21 of the gripping assembly 20 and protrude downward toward the bottom side of the sole; wherein, after the gripping assembly 20 is fixedly mounted on the shock absorbing assembly 10, the bottom side surfaces of the two are flush at the joint.

[0055] Among them, the shock-absorbing component 10 includes an upper shock-absorbing component 14 and a lower shock-absorbing component 15 which are connected to each other; the bottom surface of the lower shock-absorbing component 15 is provided with the front mounting portion 11, the gripping portion 12 and the rear mounting portion 13; the upper shock-absorbing component 14 is fixedly connected to the top surface of the lower shock-absorbing component 15; the reinforcement component 40 is fixedly installed between the upper shock-absorbing component 14 and the lower shock-absorbing component 15, and extends from the forefoot area 51 of the sole to the heel area 53, and its bending strength in the front-to-back direction is higher than that of the shock-absorbing component 10.

[0056] Specifically, refer to Figure 1The shock absorbing component 10 includes an upper shock absorbing component 14 and a lower shock absorbing component 15. The bottom surface of the upper shock absorbing component 14 is connected to the top surface of the lower shock absorbing component 15. The connection between the two can be bonding or other appropriate methods. The shock absorbing component 10 formed by the combination of the upper shock absorbing component 14 and the lower shock absorbing component 15 has a conventional sole shape, wherein the thickness of the upper shock absorbing component 14 is greater than that of the lower shock absorbing component 15, and the upper shock absorbing component 14 plays a major role in shock absorbing in the shock absorbing component 10.

[0057] Among them, a mounting groove 142 is recessed on the bottom surface of the upper shock absorbing member 14, the shape of the outer peripheral edge of the mounting groove 142 is adapted to the shape of the outer peripheral edge of the upper shock absorbing member 14, and its shape and size are adapted to the shape and size of the reinforcement member 40, and the depth of the mounting groove 142 is also adapted to the thickness of the reinforcement member 40. The reinforcement member 40 can be installed in the mounting groove 142 and fixed inside the shock absorbing assembly 10 through the connection between the lower shock absorbing member 15 and the upper shock absorbing member 14. The reinforcement member 40 can be made of nylon or carbon fiber material, which has a high structural strength, and can accumulate potential energy and restore deformation after bending. When the sole bends when touching the ground, the reinforcement 40 can bend accordingly and accumulate energy, and then restore its shape and release energy when the runner pushes off the ground, thereby boosting the foot during the rolling process of the sole touching the ground, which can effectively improve the runner's athletic performance. At the same time, the reinforcement 40 can effectively improve the overall structural strength of the sole in the front and rear directions without affecting the cushioning effect of the cushioning component 10, thereby avoiding excessive bending and deformation of the sole, thereby enhancing the overall structural stability of the sole.

[0058] Furthermore, the bottom surface of the upper shock absorbing member 14 is provided with a limiting protrusion 141 at the front end position, and the lower shock absorbing member 15 is provided with a limiting groove adapted to the limiting protrusion 141 at its front end position; after the upper shock absorbing member 14 and the lower shock absorbing member 15 are fitted, the limiting protrusion 141 is embedded in the limiting groove. With such a configuration, the lower shock absorbing member 15 can form a limiting fit with the upper shock absorbing member 14 in the forward direction; when the runner is running, the lower shock absorbing member 15 contacts the ground and is subjected to a forward reaction force, and the limiting protrusion 141 limits the relative displacement between the lower shock absorbing member 15 and the upper shock absorbing member 14, thereby preventing the lower shock absorbing member 15 from being separated from the upper shock absorbing member 14.

[0059] The bottom surface of the lower shock absorbing member 15 is provided with the front mounting portion 11, the gripping portion 12 and the rear mounting portion 13. Figure 5The front mounting portion 11 has a first extension portion 111 and a second extension portion 112, both of which extend in the length direction of the sole and are connected at the front end of the lower shock absorbing member 15, thereby forming a bent structure protruding toward the front end of the sole. In this embodiment, the first extension portion 111 and the second extension portion 112 are respectively arranged near the inner foot side 61 and the outer foot side 62 of the sole, and their outer edges are connected to the side edges of the sole, and their inner edges also extend inward for a distance, thereby forming a structure surrounding the forefoot area 51 of the lower shock absorbing member 15. Among them, a plurality of clearance holes 113 are also provided on the front mounting portion 11, and these clearance holes 113 are used to make way for the spikes 30 when the grip assembly 20 is installed with the spikes 30.

[0060] Continue to refer to Figure 5 The lower shock absorbing member 15 is provided with a gripping portion 12 in the portion between the first extension portion 111 and the second extension portion 112 of the front mounting portion 11. The front end of the gripping portion 12 extends to the middle portion of the forefoot area 51 of the sole, and the rear end thereof extends to the arch area 52 of the sole. The gripping portion 12 is also provided with a plurality of first hollow holes 122 that penetrate the lower shock absorbing member 15 in the thickness direction. The first hollow holes 122 are arranged in multiple groups at intervals in a manner of being arranged obliquely relative to the length direction of the sole, and form a matrix layout. Part of the first protrusions 121 are located between adjacent first hollow holes 122, and are staggered with the first hollow holes 122 in the matrix direction to form a matrix layout similar to the first hollow holes 122. Moreover, in the gripping portion 12, the arrangement density of each first protrusion 121 has a tendency to gradually increase with the position going backward; the arrangement density of the first protrusions 121 refers to the number of the first protrusions 121 arranged per unit area.

[0061] Specifically, refer to Figure 1, the gripping portion 12 is higher than the front mounting portion 11. Here, "higher" means that the bottom surface of the gripping portion 12 is protruding from the bottom surface of the front mounting portion 11 based on the bottom surface of the front mounting portion 11. The shape of the outer peripheral edge of the gripping portion 12 is adapted to the shape of the inner edge of the front mounting portion 11, and the gripping portion 12 can be regarded as being embedded between the first extension portion 111 and the second extension portion 112 of the front mounting portion 11 in the front-to-back direction. A plurality of first protrusions 121 are protruding from the gripping portion 12. In this embodiment, the first protrusions 121 are pyramid-shaped, preferably quadrangular pyramid-shaped. In other embodiments, the first protrusions 121 can also be set to be cone-shaped or other similar shapes. At the same time, a plurality of first hollow holes 122 are also protruding from the gripping portion 12. In this embodiment, the first hollow holes 122 are quadrilateral. The front end of the gripping portion 12 extends to the middle part of the forefoot area 51 of the sole, and the rear end extends to the arch area 52 of the sole, which reasonably expands the distribution range of the gripping portion 12 on the sole, so that it can better play a gripping role during running, especially in the stage of forefoot landing and transition to arch support. On the one hand, the first hollow hole 122 can reduce the weight of the sole. For middle and long-distance running, reducing the weight of the shoe helps runners save energy and improve their athletic performance; on the other hand, without affecting the overall structural strength and gripping and shock-absorbing functions, the setting of the first hollow hole 122 enhances the deformation ability of the sole, allowing the runner's feet to move more naturally and adapt to ground changes during running.

[0062] The layout of the first hollow holes 122 and the first protrusions 121 in the gripping portion 12 is designed to be a matrix layout. Figure 5, which shows the position of the first hollow holes 122 belonging to the same column or the same row by means of dotted lines. The first hollow holes 122 belonging to the same column will be represented by a dotted line extending from the inner foot side 61 to the outer foot side 62 from front to back, and the first hollow holes 122 belonging to the same row will be represented by a dotted line extending from the outer foot side 62 to the inner foot side 61 from front to back. In this way, the layout of the first hollow holes 122 can be regarded as extending obliquely relative to the length direction of the sole. Similarly, the layout of the first protrusion 121 can also be regarded as extending obliquely relative to the length direction of the sole. Moreover, in the process of the first protrusion 121 and the first hollow hole 122 being arranged obliquely and extending, the extension arrangement trend of the first protrusion 121 and the second hollow hole 212 can also be bent to better fit the shape of the outer peripheral edge of the sole. It should be noted that the length direction referred to in this specification and claims refers to the direction adapted to the shape of the outer peripheral edge of the sole, and the front-to-back direction referred to refers to the direction from the front end of the sole to the rear end thereof. The arrangement of the first hollow hole 122 and the first protrusion 121 can reduce the influence of the first protrusion 121 on the deformation enhancement ability of the first hollow hole 122, thereby avoiding the structural conflict between the two; and when the sole touches the ground, the first protrusion 121 will be embedded in the ground after contacting the ground, and at the same time, part of the pushed ground will sink into the first hollow hole 122 near the first protrusion 121, so that the first hollow hole 122 can also form an interaction with the ground, thereby further enhancing the sole's grip on the ground.

[0063] In addition, refer to Figure 5 The arrangement density of the first protrusions 121 in the grip portion 12 increases toward the rear. Since the front end of the grip portion 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 runs, increasing the arrangement density of the first protrusions 121 of the grip portion 12 in this area can make the grip performance of this part stronger, while the density of the first protrusions 121 on the rear side can be appropriately reduced so that the sole can have better deformation ability.

[0064] Reference Figure 1 The grip assembly 20 includes a front grip member 21 and a rear grip member 22. Figure 4 and Figure 5 The shape of the front gripping member 21 is adapted to the shape of the front mounting portion 11 of the lower shock-absorbing member 15, and a first extension arm is provided corresponding to the first extension portion 111, and a second extension arm is provided corresponding to the second extension portion 112. The first extension arm and the second extension arm are connected at the front end position of the sole, so that the shape of the front gripping member 21 is a bent shape protruding toward 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 gripping member 21 is fixedly installed to the front mounting portion 11, the gripping portion 12 can be embedded in the bending groove 214.

[0065] The bottom surface of the front gripping member 21 is provided with a plurality of second protrusions 211 protruding toward the bottom side of the sole, and is also provided with a plurality of second hollow holes 212 penetrating the front gripping member 21 in the thickness direction, and the second hollow holes 212 are arranged at intervals in a manner of being inclined relative to the length direction of the sole. The second protrusions 211 are also arranged roughly staggered with the second hollow holes 212, and the second protrusions 211 are pyramid-shaped, preferably quadrangular pyramid-shaped. In other embodiments, the second protrusions 211 can also be set to a cone or other similar shapes. The shape of the second hollow hole 212 is a quadrilateral. In addition, a nail stand 213 that is the same number as the shoe spikes 30 is also provided on the front gripping member 21, and the nail stand 213 can be used for the shoe spikes 30 to be installed and fixed. A second hollow hole 212 is provided on the front gripping member 21, which can further reduce the weight of the front gripping member 21; at the same time, the second protrusion 211 will be embedded in the ground after contacting the ground, and at the same time, part of the pushed ground 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, refer to Figure 3 and Figure 4 The rear end of the first extension arm of the front gripping member 21 is located at the connection between the forefoot area 51 and the arch area 52 of the sole, and the rear end of the second extension arm is located at 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 front gripping member 21 is bent with inconsistent heights at both ends; such a configuration enables the bending of the front gripping member 21 to adapt to the shape of the sole of the human foot, further enhancing the support effect on the human foot at the outer foot side 62.

[0067] In addition, refer to Figure 4 In the front gripping member 21, the arrangement density of each of the second protrusions 211 has a tendency to increase first and then decrease; the arrangement density of the second protrusions 211 refers to the number of the second protrusions 211 arranged per unit area. The arrangement density of the first protrusions 121 in the front gripping member 21 increases first and then decreases, that is, the arrangement density of the first protrusions 121 in the front part of the front gripping member 21 is small, the arrangement density of the first protrusions 121 in the middle part is large, and the arrangement density of the first protrusions 121 in the rear part becomes small again. This arrangement can make the grip performance of the middle part of the front gripping member 21 stronger, and the part near the arch area 52 at the rear side 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. The spike seat 32 is fixed on the spike platform 213 of the front gripping member 21. According to different situations, different lengths of the spike body 31 can be selected to be installed in the spike seat 32 to expand the application range of the spike shoe.

[0069] The shoe sole suitable for middle and long distance running involved in the embodiment of the present invention comprises a shock absorbing component 10, a gripping component 20 and a plurality of spikes 30, wherein the spikes 30 are arranged on the gripping component 20 and protrude toward the bottom side of the sole, so that the sole can maintain a certain grip; the shock absorbing component 10 is arranged according to the shape of the sole and is suitable for making the sole have a shock absorbing performance, and it can be made of a conventional material with a shock absorbing performance, such as EVA foam material, etc.; the gripping component 20 comprises a front gripping piece 21 and a rear gripping piece 22, and the structural strength of the gripping component 20 is higher than that of the shock absorbing component 10, and it can be made of a conventional material with high structural strength, such as nylon, etc., which is used to provide good grip for the sole when the sole contacts the ground; wherein the shock absorbing component 10 is provided with a front mounting portion 1 1. The gripping portion 12 and the rear mounting portion 13. The front gripping member 21 and the rear gripping member 22 of the gripping assembly 20 are fixedly mounted on the front mounting portion 11 and the rear mounting portion 13, respectively. After the gripping assembly 20 is fixedly mounted on the shock absorbing assembly 10, the bottom surfaces of the two are flush at the joint. At the same time, the gripping portion 12 is higher than the front mounting portion 11. This arrangement enables the bottom surface of the sole to form a structure in which the gripping assembly 20 and the shock absorbing assembly 10 are arranged at intervals. When the bottom surface of the sole touches the ground, the gripping assembly 20 and the shock absorbing assembly 10 will both contact the ground. Since the shock absorbing assembly 10 directly contacts the ground, the influence of the hard outsole on the shock absorbing performance of the sole is effectively reduced. At the same time, the gripping assembly 20 made of a harder material also contacts the ground, so that the sole still has good Grip performance and wear resistance; wherein, a first protrusion 121 is further provided on the grip portion 12, and a second protrusion 211 and a third protrusion 221 are respectively provided on the front grip piece 21 and the rear grip piece 22, wherein the first protrusion 121 and the second protrusion 211 are mainly distributed in the forefoot area 51 of the sole, and when the runner runs, it is mainly the forefoot area 51 that contacts the ground and provides grip for the sole to drive the runner to move forward, and the first protrusion 121 and the second protrusion 211 added to the forefoot area 51 can be embedded in the ground when the sole touches the ground, thereby improving the grip performance of the sole; and due to the different materials of the front grip piece 21 and the shock absorbing component 10, the deformation of the first protrusion 121 and the second protrusion 211 when touching the ground is also different, and the first protrusion 121 and the second protrusion 211 are different. The first protrusion 121 is softer and thus has a greater deformation. Since the gripping portion 12 is located between the first extension arm and the second extension arm of the front gripping member 21, the first protrusion 121 and the second protrusion 211 can cooperate with each other. When the second protrusion 211 is firmly embedded in the ground when the sole touches the ground, the first protrusion 121 can be slightly deformed to increase the contact area between the sole and the ground. At the same time, the impact force of the ground can be transmitted to the entire shock-absorbing component 10 through the protruding structure of the first protrusion 121, so that the shock-absorbing component 10 can quickly absorb the impact force of the ground. The third protrusion 221 provided on the rear gripping member 22 can effectively improve the stability of the runner's heel when the runner is performing middle and long-distance running, and improve the anti-slip performance of the heel position.At the same time, the front gripping member 21 is configured to be a bent shape formed by connecting the first extension arm and the second extension arm, and the gripping portion 12 is configured between the first extension arm and the second extension arm of the front gripping member 21. This configuration enhances the structural strength of the sole at the inner foot side 61 edge and the outer foot side 62 edge, so that the sole can provide better support for the foot at the inner foot side 61 and the outer foot side 62; and, due to the shape characteristics of the front gripping member 21, when the sole touches the ground and bends, the first extension arm and the second extension arm will bend, and the empty part between the first extension arm and the second extension arm will make the bending and rebound performance of the front gripping member 21 better, avoiding the forefoot area 51 being too hard to bend, resulting in excessive impact force on the foot when the sole touches the ground; therefore, the sole adopting the above structure can provide runners with good ground grip and better shock absorption performance, and better meet the running needs of middle and long-distance runners. ;

[0070] The spiked shoes involved in the embodiments of the present invention include the above-mentioned sole suitable for middle and long-distance running and a shoe body, the bottom is connected to the top side surface of the sole, and the sole with excellent performance is applied to the spiked shoe product, so that the entire spiked shoe has the advantage of a good balance between grip and shock absorption effect brought by the sole, and can provide middle and long-distance runners with a comfortable, safe and reliable wearing experience, and meet the professional requirements of middle and long-distance running events for shoes.

[0071] The description of the above specification and embodiments is used to explain the protection scope of the present invention, but does not constitute a limitation on the protection scope of the present invention. Through the enlightenment of the present invention or the above embodiments, ordinary technicians in this field can obtain modifications, equivalent substitutions or other improvements to the embodiments of the present invention or part of the technical features thereof through logical analysis, reasoning or limited experiments, which should be included in the protection scope of the present invention.
