Description

A sports shoe sole Technical Field

[0001] The present application relates to the technical field of sports shoes, and in particular to a sports shoe sole. Background Art

[0002] Shoes are essential daily necessities, and the sole is a crucial component. It not only provides the primary protective function, but also the shoe's elasticity, slip resistance, and comfort all depend on its structure and material. To increase friction between the shoe and the ground during walking and reduce the impact of the ground on the foot joints, particularly in Frisbee, the sole must not only provide a certain degree of elasticity but, most importantly, sufficient friction and grip to support the athlete's explosive movements in all directions. For example, when catching a flying disc that is taller than the athlete, the athlete needs to retreat quickly. During this retreat, the athlete primarily relies on the forefoot and toes for friction. When avoiding obstacles or chasing a Frisbee, the athlete must make sudden stops and turns, and the forefoot must provide not only sufficient grip but also lateral friction. When diving forward, the heel of the backfoot needs to withstand the pressure exerted by the leg muscles and generate significant friction. Furthermore, when jumping mid-air to catch a Frisbee, the sole requires a relatively light weight. Technical issues

[0034] The realization of the objectives, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. Modes for Carrying Out the Invention

[0035] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0036] The present application provides a sports shoe sole.

[0037] In the embodiment of the present application, the sports shoe sole is shown in Figures 1 to 6 and includes:

[0038] midsole 10; and

[0039] The outsole 20 is provided on the bottom surface of the midsole 10. The outsole 20 includes a forefoot portion 30 and a rearfoot portion 40 spaced apart from each other. The space between the forefoot portion 30 and the rearfoot portion 40 corresponds to the midfoot region 80 of the foot. The forefoot portion 30 and the rearfoot portion 40 are each provided with a plurality of anti-slip studs 50. At least two anti-slip studs 50 located on the forefoot portion 30 extend forward, and at least one anti-slip stud 50 extends rearward. At least two anti-slip studs 50 located on the rearfoot portion 40 extend rearward, and at least one anti-slip stud 50 extends forward.

[0040] Both the forefoot portion 30 and the rear foot portion 40 are provided with weight-reducing holes 60 , and the forefoot portion 30 is further provided with a torsion ring groove 70 corresponding to the rear area of ​​the big toe of the foot.

[0041] The technical solution of this application utilizes anti-slip spikes 50, making the sole of the sports shoe more suitable for outdoor use on grass and other surfaces. This increases the grip of the sole with the ground and allows it to adapt to changes in grip in multiple directions. The spaced-apart forefoot 30 and rearfoot 40 allow the sole to bend and deform more easily, better adapting to the athlete's forefoot-driven movements, such as jumps, thereby ensuring a better fit between the sole and the foot. Furthermore, the torsion ring groove 70, acting as a torsion point, provides multi-directional friction for sharp turns initiated from the inner forefoot area. This, in conjunction with the anti-slip spikes 50, prevents athletes from slipping and falling during these turns. Furthermore, the weight-reducing holes 60 reduce the weight of the outsole 20, making the overall sports shoe lighter and more portable, facilitating easy and flexible use for movements such as quick movements and jumps.

[0042] The inner side and outer side of the sole correspond to the inner side and outer side of the sole of the foot respectively. Generally speaking, the side of the sole with the thumb is defined as the inner side, and the side of the sole with the little toe is defined as the outer side.

[0043] Optionally, the plurality of anti-slip spikes 50 located on the forefoot portion 30 include a first spike body 51, a second spike body 52, a third spike body 53, and a fourth spike body 54. The first spike body 51 is located on the inner side of the forefoot portion 30, the second spike body 52 is located on the outer side of the forefoot portion 30, the third spike body 53 is located at the front end of the central axis of the forefoot portion 30 and extends forward, and the fourth spike body 54 is located at the rear end of the central axis of the forefoot portion 30 and extends backward. In the forward direction, the first spike body 51 and the second spike body 52 are both arranged to extend obliquely in a direction close to the central axis of the forefoot portion 30. The first spike body 51 is used to support the inner side of the sole, and the second spike body 52 is used to support the outer side of the sole. This can also prevent the athlete from slipping when performing an emergency stop. When the athlete performs an emergency stop and turn, the first spike body 51 and the second spike body 52 cooperate with each other to enable the athlete to turn smoothly and quickly. The third nail 53 prevents the front end of the sole from slipping. Since the toes of the forefoot rub against the ground when an athlete performs a quick backward movement, the third nail 53 helps the athlete maintain a stable backward motion. The fourth nail 54 prevents the rear end of the forefoot 30 from slipping. When athletes run quickly, the forefoot is often the last to leave the ground. The first, second, and fourth nails 51, 52, and 54 work together to provide a boost to the forefoot. In other embodiments, the forefoot 30 may not include the fourth nail 54.

[0044] Optionally, the plurality of anti-slip studs 50 located on the rear sole portion 40 include a fifth stud 55, a sixth stud 56, and a seventh stud 57. The fifth stud 55 is located on the inner side of the rear sole portion 40, the sixth stud 56 is located on the outer side of the rear sole portion 40, and the seventh stud 57 is located forward of the central axis of the rear sole portion 40 and extends forward. In the forward direction, the fifth and sixth studs 55, 56 are both arranged to extend obliquely toward the central axis of the rear sole portion 40. The fifth, sixth, and seventh studs 55, 56, 57 collectively provide anti-slip support for the rear sole, with the sixth stud 56 providing lateral friction during turning motion. In other embodiments, the fifth stud 55 may not be provided.

[0045] Optionally, the cross-section of the first and second nail bodies 51, 52 is triangular, with the sharp corners of the triangle facing forward along its long axis. This triangle provides greater force stability and can exert multi-directional friction on the ground without damaging the grass. When the athlete runs forward, the hypotenuse of the triangle along its long axis is subjected to forward-directed friction from the ground, which helps propel the forefoot. In other embodiments, the cross-section of the first and second nail bodies 51, 52 can also be circular.

[0046] Optionally, the cross-section of the fifth and sixth nail bodies 55, 56 is triangular, with the sharp corners of the triangle facing rearward along its major axis. When an athlete runs forward, the forces acting on the forefoot and the rearfoot are in opposite directions. Therefore, when the sharp corners of the triangle face rearward along its major axis, the athlete's running is facilitated. In other embodiments, the cross-section of the fifth and sixth nail bodies 55, 56 can also be circular.

[0047] Optionally, the cross-sectional shape of the third and seventh nail bodies 53 and 57 is a concave quadrilateral, with the concave quadrilateral protruding forward. When an athlete turns, the outer side of the forefoot portion 30 is subjected to frictional forces in multiple directions. Since the front end of the forefoot portion 30 is relatively small, to ensure that the front end of the forefoot portion 30 withstands frictional forces in multiple directions, the cross-sectional shape of the third nail body 53 is a concave quadrilateral, with the concave quadrilateral protruding forward. Specifically, the concave quadrilateral has two adjacent side edges arranged along the front contour of the sole. These two adjacent side edges can respectively withstand frictional forces directed from the front end toward the rear end of the sole, as well as frictional forces transmitted from the left and right side surfaces of the sole. On the rearfoot portion 40 of the sole, the seven nail body 57 has two adjacent side edges arranged along the front contour of the rearfoot portion 40. When an athlete turns, these two adjacent side edges can respectively withstand frictional forces directed from the front end toward the rear end of the sole, as well as frictional forces transmitted from the left and right side surfaces of the sole. In other embodiments, the cross-sectional shape of the third nail body 53 and the seventh nail body 57 may be configured as a parallelogram, and both sides of the obtuse angle in the parallelogram may be arranged to protrude forward.

[0048] Optionally, the cross-sectional shape of the fourth nail body 54 is configured as a concave quadrilateral, with the concave quadrilateral protruding rearward. When the athlete turns, the rear end of the forefoot portion 30 will also be subjected to frictional forces in a more directional manner. Therefore, the cross-sectional shape of the fourth nail body 54 is configured as a concave quadrilateral, with the concave quadrilateral protruding rearward. In other words, the two adjacent sides of the concave quadrilateral are arranged along the rear end contour of the forefoot portion 30. These two adjacent sides can respectively withstand frictional forces directed from the rear end of the sole toward the front end, as well as frictional forces transmitted from the two side surfaces of the sole in the left-right direction. In other embodiments, the cross-sectional shape of the fourth nail body 54 can also be configured as a parallelogram, with the two sides of the obtuse angle of the parallelogram protruding rearward.

[0049] Optionally, the rear end surface of the third nail body 53 in the direction of its mid-axis is provided with a third sloped surface 531, which is configured as an inwardly concave arc. When the third nail body 53 is subjected to frictional force directed from the front end of the sole toward the rear end, the third nail body 53 will deform to a certain extent, that is, the third sloped surface 531 will be squeezed. Therefore, the third sloped surface 531 is configured as an inwardly concave arc, so that the third sloped surface 531 has space to deform toward the center of the inwardly concave arc, thereby preventing damage to the third nail body 53. In this case, the third nail body 53 has a "V"-shaped structure, and the thickness of the "V"-shaped protrusion gradually increases from its open end to its tip. This ensures that the sole of the shoe provides sufficient backward friction when the athlete performs a backward movement, while also ensuring the athlete's stability during the backward movement. In other embodiments, there may be two third nail bodies 53, which are arranged at intervals along the left and right directions of the sole, wherein the one located on the left side of the sole has a third slope surface 531 on the right side in the direction of its central axis, and the one located on the right side of the sole has a third slope surface 531 on the left side in the direction of its central axis, and the third slope surface 531 is arranged as an inwardly concave arc surface.

[0050] Optionally, the front end surface of the fourth nail body 54 in the axial direction thereof is provided with a third slope surface 531 , and the rear end surface of the seventh nail body 57 in the axial direction thereof is provided with a third slope surface 531 , and the third slope surface 531 is provided in an inwardly concave arc surface.

[0051] Optionally, the weight-reducing holes 60 located in the forefoot portion 30 include a first hole 61 and a second hole 62 spaced apart in the front-to-back direction. The first hole 61 is positioned forward, and the torsion ring groove 70 is located between the first hole 61 and the second hole 62. An anti-slip stud 50 is located in the gap between the first and second holes 61, 62. This provides sufficient support for the inner side of the forefoot portion 30 while reducing the weight of the forefoot portion 30. In other embodiments, the weight-reducing holes 60 located in the forefoot portion 30 may include a first hole 61 and a second hole 62 spaced apart in the left-to-right direction.

[0052] Optionally, the weight-reducing holes further include a fourth hole 64, which is located between the first hole 61 and the second hole 62 and spaced apart from both the first hole 61 and the second hole 62. A row of anti-slip studs 50 is provided in the space between the first hole 61 and the fourth hole 64, and another row of anti-slip studs 50 is provided in the space between the fourth hole 64 and the second hole 62. The first, second, and fourth holes 61, 62, and the anti-slip studs 50 are evenly distributed across the forefoot portion 30, minimizing the weight of the forefoot portion 30. In other embodiments, the fourth hole 64 may be omitted, and the second hole 62 may be located near the rear end of the forefoot portion 30, so that at least two rows of anti-slip studs 50 are provided in the space between the first and second holes 61, 62.

[0053] Optionally, the first holes 61 are shaped as a parallelogram, and the second holes 62 are shaped as a concave quadrilateral. This allows the first nails 51 to be arranged in a V-shaped configuration. This means that while the first nails 51 provide support, shock absorption, and anti-slip functions, the arrangement also offers a certain degree of anti-slip properties. In other embodiments, the second holes 62 can be configured as elongated strips.

[0054] Optionally, the front end of the second nail body 52 along its longitudinal axis is provided with a first sloped surface 521. Since an athlete typically leaves the ground with their forefoot when pushing off, the bottom contour of the midsole 10 is designed to resemble a boat shape, with both front and rear ends curved upward to better conform to the curvature of the forefoot. When the forefoot pushes off the ground, the first sloped surface 521 contacts the ground. This reduces the slope and extends the slope of the first sloped surface 521, which helps increase the contact area between the second nail body 52 and the ground, enhancing grip. Furthermore, the structure of the first sloped surface 521 creates a trapezoidal vertical cross-section of the second nail body 52, meaning that the contact area between the second nail body 52 and the outsole 20 is greater than the contact area between the second nail body 52 and the ground. This structure provides a shock-absorbing and cushioning effect. In other embodiments, the second nail body 52 may not be provided with the first sloped surface 521.

[0055] Further optionally, the front end of the first nail body 51 along its longitudinal axis is provided with a first slope 521. When the forefoot pushes off the ground, the first slope 521 contacts the ground, making the first slope 521 have a small slope and a long slope, thereby increasing the contact area between the first nail body 51 and the ground and enhancing grip. The arrangement of the first slope 521 and the second slope 522 results in a trapezoidal vertical cross-section of the first nail body 51. This means that the contact area between the first nail body 51 and the outsole 20 is greater than the contact area with the ground, providing a shock-absorbing and cushioning effect. In other embodiments, the first nail body 51 may not be provided with the first slope 521.

[0056] Optionally, the rear end surface of the second nail body 52 located behind the second hole 62 is provided with a second slope 522, and the slope of the first slope 521 is equal to the slope of the second slope 522. When the forefoot pushes off the ground, the second nail body 52 located behind the second hole 62 is lifted off the ground, so the first slope 521 does not contact the ground. Furthermore, the structure of the first slope 521 and the second slope 522 gives the second nail body 52 a trapezoidal vertical cross-section. This means that the contact area of ​​the second nail body 52 with the outsole 20 is greater than the contact area with the ground, providing a shock-absorbing and cushioning effect. In other embodiments, the second nail body 52 located behind the second hole 62 may not be provided with the first slope 521 and the second slope 522.

[0057] Further optionally, the rear end surface of the first nail body 51 located behind the second hole 62 is provided with a second slope 522, and the slope of the first slope 521 is equal to the slope of the second slope 522. When the forefoot pushes off the ground, the first nail body 51 located behind the second hole 62 is lifted off the ground, so the first slope 521 does not contact the ground. The structure of the first slope 521 and the second slope 522 gives the first nail body 51 a trapezoidal vertical cross-section. In other embodiments, the first nail body 51 located behind the second hole 62 may not be provided with the first slope 521 and the second slope 522.

[0058] Optionally, the weight-reducing holes 60 located in the rear palm portion 40 include two third holes 63 arranged opposite each other in the left-right direction, with multiple anti-slip nails 50 arranged circumferentially around the third holes 63. Specifically, the fifth nail 55 is located in the gap between the two third holes 63, and the sixth nail 56 is located in another area of ​​the rear palm portion 40. This allows the fifth nail 55 to fully support the inner side of the fore palm portion 30 while reducing the weight of the rear palm portion 40. In other embodiments, there may be only one third hole 63, located near the front end of the rear palm portion 40.

[0059] Further optionally, the fifth nail body 55 and the sixth nail body 56 each have a first sloped surface 521 on their rear end surfaces in the longitudinal direction. Generally, when running, the sole of the foot touches the ground first. When the sole of the foot touches the ground first, the warped portion of the rear end of the sole contacts the ground first, meaning the first sloped surface contacts the ground first, providing an anti-slip effect. The structure of the first sloped surface 521 causes the vertical cross-section of the second nail body 52 to be trapezoidal, meaning the contact area between the second nail body 52 and the outsole 20 is greater than the contact area with the ground. This structure provides a shock-absorbing and buffering effect, effectively mitigating damage to the knees and hip bones caused by running. In other embodiments, the second nail body 52 may not have the first sloped surface 521 or the second sloped surface 522.

[0060] Further optionally, the fifth and sixth nail bodies 55, 56 at the front side of the third hole 63 are each provided with a second slope 522 on their front end surfaces in the longitudinal direction, and the slope of the first slope 521 is equal to the slope of the second slope 522. Because there is no movable bone joint between the rearfoot and the midfoot, when the forefoot lands, the fifth and sixth nail bodies 55, 56 at the front side of the third hole 63 contact the ground. During this process, the first slope 521 of the fifth and sixth nail bodies 55, 56 at the front side of the third hole 63 does not contact the ground. The structure of the first slope 521 and the second slope 522 gives the fifth and sixth nail bodies 55, 56 an isosceles trapezoidal vertical cross-section. That is, the contact area of ​​the fifth and sixth nail bodies 55, 56 with the outsole 20 is greater than the contact area with the ground. This structure has a shock-absorbing and buffering effect. In other embodiments, the fifth nail body 55 and the sixth nail body 56 located in front of the third hole 63 may not be provided with the first slope 521 and the second slope 522 .

[0061] Optionally, a groove 58 is provided in the middle of the anti-slip nail 50. When the anti-slip nail 50 is subjected to friction, the anti-slip nail 50 is squeezed and deformed. Providing the groove 58 in the middle of the anti-slip nail 50 can increase the deformation range of the anti-slip nail 50, buffering the frictional force exerted on the anti-slip nail 50 and increasing the frictional force that the anti-slip nail can withstand. In other embodiments, the anti-slip nail 50 can also be provided without the groove 58 in the middle.

[0062] The above description is merely an optional embodiment of the present application and does not limit the patent scope of the present application. All equivalent structural transformations made using the contents of the present application specification and drawings under the inventive concept of the present application, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
