[0013] The technical scheme of the utility model will be described clearly and completely in combination with the drawings and specific embodiments, and it should be understood that the preferred embodiments described here are only for illustrating and explaining the utility model and cannot be understood as the limitation of the protection scope of the utility model, and the skilled person in the art can make some non-essential improvements and adjustments according to the content of the utility model. In the utility model, unless otherwise explicitly specified and limited, the technical terms used in the application should be the common meaning understood by the technical personnel described in the utility model.

[0014] As Figure 1 And Figure 2 A light shoe sole with good resilience is shown in the drawings, and the outer layer bottom 1 is provided with a groove 2, the high resilience foaming layer 3 and the support layer 4 are sequentially arranged in the groove 2 from bottom to top, the material of the support layer 4 is carbon fiber, the support layer is provided with the toe bone support part 5 corresponding to each phalanx at the toe part, and the adjacent toe bone support parts 5 are hollowly arranged.

[0015] The toe bone support part corresponding to each phalanx is arranged, and the adjacent toe bone support parts 5 are hollowly arranged, which can not only enhance the support of the shoe sole to the toes, but also can improve the bending property of the shoe sole at the metatarsal position. The toe bone support part supports the corresponding toes, that is, precise support and protection are provided for the toes, and the amount of carbon fiber can be reduced.

[0016] The groove 2 is arranged on the outer layer bottom 1 and is communicated from front to back, which can increase the elasticity as much as possible and more effectively reduce the weight of the shoe sole.

[0017] The support layer 4 is provided with the toe bone support part 5 corresponding to each phalanx at the toe part, and the adjacent toe bone support parts are hollowly arranged.

[0018] The support layer 4 is arranged in an arc shape with gradually decreasing height from the instep corresponding part 40 to the metatarsal bone bottom corresponding part, and arranged in an arc shape with gradually increasing height from the metatarsal bone bottom corresponding part to the distal phalanx corresponding part 41. The support layer 4 is ergonomic, conforms to the shape of the foot, supports the joint stress part, and enhances the support performance of the shoe sole.

[0019] In terms of length, the support layer 4 gradually thins from the heel center to the forefoot, and in terms of width, the thickness of the support layer 4 gradually thins from the center to both sides. This facilitates foot support while increasing comfort.

[0020] The thickness of the support layer 4 is 1-2 mm, and the longitudinal stiffness is ≥400 KN·mm 2 The longitudinal direction is the length direction of the support layer, that is, the direction from the toe to the heel. The transverse stiffness can also be ≥400 KN·mm 2 The transverse stiffness is the width direction of the support layer 4.

[0021] The carbon fiber support layer has high strength and can effectively enhance the structural stability of the shoe sole. Therefore, through the design of the high-resilience foaming layer 3 and the carbon fiber support layer, the weight of the shoe sole can be effectively reduced on the basis of ensuring the support performance of the shoe sole to the foot.

[0022] The minimum depth of the groove 2 of the outer bottom is greater than or equal to 6 mm, and the maximum depth is less than or equal to 12 mm; the high-resilience foaming layer 3 and the groove 2 of the outer bottom are bonded by an adhesive.

[0023] The high-resilience injection-molded foaming layer is obtained by injecting and foaming in the groove 2. Due to the small height of the groove and the relatively narrow space, the foaming of the high-resilience injection-molded foaming layer will be relatively uneven, and many bubbles will exist. Moreover, the heel part of the groove on the outer bottom is injected, and during the flow to the instep part, the thickness of the groove thins due to the fact that the thickness of the heel of the shoe sole is generally greater than that of the instep, which may cause poor forward flow and poor foaming effect. Moreover, under the condition of a certain space, if the injected PU material is insufficient, the density is low, the formed product will be too soft, and the exposed part of the side wall is prone to breakage. If the injected PU material is excessive, the density is large, and the weight is large, the elasticity is not good. Since the high-resilience foaming material is filled, the space is limited, and it is difficult to achieve balance.

[0024] Therefore, the high-resilience foaming layer 3 and the groove 2 of the outer bottom are bonded by an adhesive, which can have a relatively large space to set the high-resilience foaming layer 3.

[0025] The thickness of the high-resilience foaming layer 3 is greater than or equal to 6 mm, and the thickness is less than or equal to 12 mm. The drop ball rebound resilience is 69%-73%, and the density is 0.05±0.01 g / cm 3 . For example, the drop ball rebound resilience is 71%, and the density is 0.05±0.01 g / cm 3 .

[0026] The material of the high-resilience foaming layer 3 is TPU foaming material. The TPU foaming material has light weight and energy feedback, and provides good cushioning effect and walking comfort.

[0027] The material of the outer layer bottom 1 is wear-resistant rubber material, and the wear-resistant rubber material commonly used as the outer layer bottom in the prior art can be used, and thus is not specifically limited herein. The wear-resistant rubber material ensures the durability and grip of the shoe sole in various environments.

[0028] The light-weight shoe sole with good resilience provided by the utility model provides a new technical solution for shoe and boot products, such as training shoes, combat boots and outdoor sports shoes, which need to be used in high-strength and complex environments, and has wide market application prospect and social value.
