TECHNICAL FIELD
[0001] The utility model relates to the field of sports goods, especially to a sole of sports shoes and sports shoes with the sole. BACKGROUND
[0002] Sole for shoes, especially for sports shoes such as running shoes, has been widely recognized and increasingly popular among individual users due to its diverse purposes and use scenarios. The sole usually has multiple functions to enhance the attractiveness to individuals.
[0003] For example, the sole is mainly used for protection purposes, such as preventing the wearer's feet from being disturbed or damaged by external objects, such as sharp or protruding objects that may be stepped on. In addition, the sole helps to cushion the impact force generated when the foot hits the ground and provides the necessary traction to prevent the wearer from slipping. The sole also provides a certain degree of stability to the wearer's foot, thereby reducing the risk of spraining the ankle or other types of injuries, including plantar fasciitis or muscle overload, etc.
[0004] In particular, another important function of the sole, especially for high-performance running shoes, is to facilitate the efficient transfer of force from the athlete's leg through the foot to the ground and help form an efficient running style to enhance the athlete's performance. For sports shoes, it is particularly critical that the sole provides sufficient cushioning to reduce the impact and load on the athlete's joints. At the same time, the sole should be as light as possible to further reduce the athlete's energy consumption, which is particularly important in long-distance sports.
[0005] Against this background, some particularly critical needs have emerged: on the one hand, the sole needs to achieve a high degree of cushioning and stability to reduce the risk of injury and enhance the comfort of sports activities; on the other hand, it needs to ensure high energy feedback to simultaneously reduce the energy consumption required by the athlete during the exercise.
[0006] In view of the above needs, there are still some deficiencies in the existing designs. For example, most known solutions mainly focus on heel impact and require additional components with a larger volume to achieve the cushioning effect. However, these solutions do not achieve the best energy rebound effect. In addition, high-performance lightweight foam can provide more deformation, thereby enhancing the cushioning effect, but its high energy rebound characteristics cause adverse loads on the athlete's knees and other parts.
[0007] Based on this background, the core objective of the present utility model is to provide an improved sole to at least partially overcome the deficiencies of the prior art. Specifically, the present utility model aims to develop a sole that can enhance the cushioning effect while effectively reducing the impact on the wearer's foot, thereby reducing the risk of injury, and at the same time, reducing the weight of the sports shoes and the cost.

[0057] Referring to Figures 1 to 4 , a schematic view of a sole 100 of an athletic shoe under different viewing angles according to the present application is shown. In this embodiment, in order to realize the "inlaid separation" structure design of the midsole 110, the structure design of the sole 100 includes the midsole 110 and the outsole 120. The outsole 120 has a ground contact surface and a mounting surface. The ground contact surface is the end surface in contact with the ground, and the mounting surface is the end surface opposite to the ground contact surface. The midsole 110 is disposed on the outsole 120. When a user wears the athletic shoe with the sole 100 and directly or indirectly steps on the midsole 110, the midsole 110 provides a rebound force to the user. In this embodiment, the midsole 110 includes a first midsole unit 111 and a second midsole unit 112. The structure of the two parts first presents a separated design of the midsole 110, and secondly, the first midsole unit 111 includes a first support portion 113 and a second support portion 114. The first support portion 113 is attached to the mounting surface of the outsole 120. When the first support portion 113 is in contact with the outsole 120, it deforms to form a rebound force when receiving the stepping force of the user, and at the same time, it transmits the force to the outsole 120 until it is transmitted to the ground to disperse the received stepping force. The second support portion 114 is fixed to the edge of the first support portion 113 and extends in a direction opposite to the outsole 120 (the extension direction can be perpendicular to the first support portion 113 or at a certain inclination angle). Thus, the second support portion 114 is arranged around the edge of the first support portion 113, so that the entire first midsole unit 111 has a "boat shape" and forms an accommodation space 115 inside.
[0058] On this basis, the second midsole unit 112 is arranged in the accommodation space 115. The projection area of the second midsole unit 112 in the axial direction of the midsole 110 can be equal to or less than the first support portion 113, that is, the second midsole unit 112 can be completely attached to the first support portion 113, or some displacement space can be reserved. The second midsole unit 112 can be designed to have different thicknesses according to the user's demand for the softness of the sole 100, but it needs to meet the structure of being completely contained in the accommodation space 115, that is, the second midsole unit 112 does not protrude from the second support portion 114. When the user's foot is placed on the sole 100, the side edge of the foot is surrounded by a part of the second support portion 114. On the one hand, it can wrap the foot, and on the other hand, the deformation of the second midsole unit 112 will be limited by the first midsole unit 111, so that the part of the midsole 110 is more stable, the metatarsophalangeal joint part is less likely to deform, and the foot rigidity is stronger.
[0059] Continuing to refer to Figure 1 and Figure 2In a preferred embodiment, to further provide the rebound force, the sole 100 further comprises a carbon plate 130 installed between the first midsole unit 111 and the second midsole unit 112, when the sole 100 receives the stepping force from the user, the first midsole unit 111, the second midsole unit 112 and the carbon plate 130 will all be deformed to provide the rebound force, in addition, the carbon plate 130 is embedded between the first midsole unit 111 and the second midsole unit 112, so that it is closer to the ground, the deformation amount is small, the rebound response speed is faster, and it is suitable for high step frequency trail runners. Further, the second midsole unit 112 is further provided with at least one hollow part 116, the hollow part 116 penetrates the second support part 114 along the radial direction of the second support part 114, so that the second support part 114 has a visual window, the user can directly observe the second midsole unit 112 stored inside along the radial direction of the second support part 114, through the design of the hollow part 116, the user can observe the existence and thickness of the second midsole unit 112, and has a certain evaluation on the rebound force that the sole 100 can produce; on the other hand, it can reduce the mass of the midsole 110, and provide a lightweight design for the sports shoes.
[0060] Further, the outer end surface of the second support part 114, i.e. the outer side end surface, is provided with at least one groove 117, any or any groove 117 extends from the fixed end to the free end of the second support part 114 along a direction at a certain angle with the axial direction of the second support part 114, for example, it can extend along the vertical direction, or at a certain angle of 10°-80° with the vertical direction. In other words, the groove 117 is recessed on the outer end surface of the second support part 114, and the outer end surface is divided in a strip shape, correspondingly, the hollow part 116 is arranged between any two adjacent grooves 117, and the hollow part 116 can be arranged from the middle part of the outer end surface, i.e. not from the fixed end to the free end of the second support part 114. The groove 117 can further reduce the mass of the midsole 110, and at the same time provide a line design for the side surface of the midsole 110, on the other hand, the second support part 114 still has a certain supporting force, it can be understood that the number of grooves 117 and hollow parts 116 can be adjusted according to the material of the second support part 114 and the expected size of the supporting force.
[0061] Preferably or alternatively, the carbon plate 130 comprises a front plate 131 and a rear plate 132, the arrangement direction of the front plate 131 and the rear plate 132 is along the forefoot-to-rearfoot direction of the sole 100. The front plate 131 comprises a first plate strip 133 and a second plate strip 134, the first plate strip 133 and the second plate strip 134 are separated to form a first separation space; the rear plate 132 comprises a third plate strip 135 and a fourth plate strip 136, the third plate strip 135 and the fourth plate strip 136 are separated to form a second separation space, so that the carbon plate 130 is X-shaped, wherein the second separation space is smaller than the first separation space, and the first separation space and the second separation space are respectively arranged on both sides of the carbon plate 130, and the middle part is the connecting part of the front plate 131 and the rear plate 132. With the above structure, the front plate 131 is arranged at the rear of the forefoot, can support the whole forefoot, and has a rebounding effect; and the rear plate 132 is arranged at the rear of the rearfoot, can support the force point of the rearfoot. In addition, the area of the carbon plate 130 accounts for 60%-85% of the projection area of the first midsole unit 111, which mainly covers the force point of the user's tread on the sole 100, can save cost and reduce weight.
[0062] In a preferred embodiment, the sole 100 further comprises a heel cup 140 for maintaining the neutral position of the heel, reducing the degree of foot eversion, and enhancing the stability during walking. The heel cup 140 can be integrally formed with the second support part 114, and the heel cup 140 is respectively provided with at least one hook 150 on the two sides in the radial direction, i.e. the two sides of the shoe body, the hook 150 extends outward in the radial direction, and provides a hooking area. When the user needs to wear a dustproof cover on the sole 100, the upper end of the dustproof cover wraps around the user's lower leg, and the lower end is hooked on the hooking area, so that the user can use the sports shoes with the sole 100 in extreme outdoor environments.
[0063] Preferably, the forefoot part of the second midsole unit 112 is provided with at least one through hole 118, the through hole 118 extends in the radial direction of the second midsole unit 112 and is cut off at the edge of the second midsole unit 112, i.e. the through hole 118 is similar to a curved groove, the two sides do not extend to the edge of the second midsole unit 112, so that the second midsole unit 112 is not divided in the middle. When the second midsole unit 112 deforms, the through hole 118 provides a deformation space, i.e. the second midsole unit 112 bends at the through hole 118, so that the second midsole unit 112 on both sides of the through hole 118 can move towards the through hole 118, and has a larger bending space.
[0064] In yet another embodiment, the ground-contacting surface of the outsole 120 is designed in zones, i.e. different zones of the ground-contacting surface provide different functions to the sole 100. Specifically, the outsole 120 comprises a front outsole 121 and a rear outsole 122; the front outsole 121 is provided with a first protrusion 123 and a second protrusion 124 extending towards the ground-contacting surface; the rear outsole 122 is provided with a third protrusion 125 and a fourth protrusion 126 extending towards the ground-contacting surface; the first protrusion 123, the second protrusion 124, the third protrusion 125 and the fourth protrusion 126 are designed in different shapes, which provide different functions to the outsole 120.
[0065] More specifically, the first protrusion 123 is disposed at the edge of the front outsole 121 and comprises a first protrusion group and a second protrusion group; the first protrusion group is directed towards the middle of the front outsole 121, i.e. the narrower tip of the first protrusion group is directed towards the middle of the front outsole 121; the second protrusion group is directed towards the radial outer part of the front outsole 121, i.e. the narrower tip of the second protrusion group is directed towards the outer part of the front outsole 121; and the first protrusion group and the second protrusion group partially overlap along the radial direction of the front outsole 121, i.e. the wider part of the first protrusion group partially overlaps with the wider part of the second protrusion group, so that the outsole 120 can provide friction in different directions when in contact with the ground, and sufficient friction can be provided regardless of the direction in which the sole 100 is moved by the user; the second protrusion 124 is disposed at the middle of the front outsole 121 and comprises a third protrusion group and a fourth protrusion group; the third protrusion group and the fourth protrusion group are in the shape of a V; the bend of the V-shaped third protrusion group and the fourth protrusion group is directed towards the front of the front outsole 121; and the free end of the third protrusion group is in contact with the middle part of the fourth protrusion group, i.e. the third protrusion group is in the shape of a small V and the fourth protrusion group is in the shape of a large V; the third protrusion group is disposed in front of the fourth protrusion group, so that the third protrusion group and the fourth protrusion group can provide sufficient friction when the sole 100 is moved by the user in the front or rear direction.

The fourth protrusion 126 is disposed at the middle of the rear outsole 122 and comprises a seventh protrusion group; the seventh protrusion group can have a plurality of protrusions symmetrically arranged along the middle line and directed towards the middle rear part of the rear outsole 122, so that the entire seventh protrusion group is in the shape of a wing. The different extension directions (i.e. the sawtooth direction) of the above-mentioned protrusion groups provide sufficient friction in different directions, so that the sole 100 has a braking effect in all directions.
[0067] Referring toFigure 5 The shoe sole 100 in any of the above embodiments can be applied to sports shoes 200 for use by a user.
