Technical Field

The utility model relates to the field of shoes, in particular to a composite sole structure and a shoe.

However, it is difficult for a common running shoe to achieve the above effects completely, and the following problems exist in the existing shoe technical scheme: (1) Most of racing shoes have thick sole structures, carbon plates are embedded in soles, and when the racing shoes are worn, the overall dynamic stability is poor when the racing shoes are landed and jumped forward by a single leg, and the dynamic stability in the left-right direction is poor when the racing shoes are landed and jumped sideways by a single leg, so that the racing shoes are easy to generate sports injury in the sports process; (2) When running for a long distance, for example, a full horse, the foot landing mode of a runner in the latter half can be changed continuously, and the runner transits from the forefoot to the midfoot landing, at this time, in the process of the transition from the heel to the midfoot, higher heel rebound resilience and cushioning property are required to compensate the muscle strength reduction phenomenon caused by the fatigue of lower limbs and foot muscles in the latter half, and the existing running shoes can not change the force feedback mechanism along with the change of the foot landing mode; (3) The racing running shoes are designed for the heel-grounded runners in most cases, but the design of the shoe body which is grounded towards the middle half sole in a targeted grounding mode is more beneficial to the top level player to exert the running gesture of the half sole grounding mode and improve the athletic performance; (4) The existing carbon plate running shoes are easy to have the condition that the half sole is hot and hard in the latter half of long-distance running, and the comfort of the running shoes is greatly affected.

The concave part 21 is concavely arranged towards the direction of the ground, the inner side upper convex part 22 and the outer side upper convex part 23 are arched towards the direction of the foot of the human body, so that a three-dimensional concave-convex structure is formed on the half sole part of the supporting plate 2, and the concave-convex structure can elastically deform in the trampling process to store or release energy, thereby providing powerful propelling performance for the trampling stage.

Further, as shown in fig. 5 to 7, the inner upper convex portion 22 and the lower concave portion 21 are connected at a portion of the support plate 2 near the toe and are broken at a portion near the midfoot, and the outer upper convex portion 23 and the lower concave portion 21 are connected at a portion of the support plate 2 near the midfoot and are broken at a portion near the toe. In combination with the force-generating characteristics of the foot of the human body in the pedaling stage, the metatarsal bone region on the outer side of the forefoot of the foot in the pedaling stage generates force first, so that the outer upper convex part 23 of the forefoot is disconnected in the toe region and connected in the midfoot region, the rigidity of one end of the midfoot can be enabled to be higher than that of one end of the toe, powerful support is provided for pedaling, and the tibia is prevented from over pronation and over inversion of the foot. Meanwhile, the foot of the human body can be internally rotated to a certain extent in the pedaling stage, and the first metatarsal region corresponding to the thumb is stressed most, so that the midfoot region of the inner upper convex part 22 is broken, the pedaling moment of the thumb can be increased, and the improvement of athletic performance is facilitated.

Further, as shown in fig. 4, the half sole portion of the first elastic layer 1 is provided with an inner concave arc 11 and an outer concave arc 12, the inner concave arc 11 and the inner upper convex portion 22 of the support plate 2 together enclose an inner hollow structure 51, and the outer concave arc 12 and the outer upper convex portion 23 together enclose an outer hollow structure 52.

The support portion 32 is narrowed in a midfoot direction of the sole on a side near the heel portion of the sole to form a cavity 6, and the cavity 6 corresponds to a region position of the first ejection portion 25 near the heel portion to provide a deformation space.

The lower part of the heel is narrowed, which is favorable for adjusting the ground running gesture of a runner, reducing the dorsiflexion angle of the ankle joint and the included angle between the shoe and the ground in the sagittal plane at the ground time, guiding the ground to the middle half sole to land, reducing the muscle work of the dorsum of the ground and the anterior tibial anterior muscle of the calf, simultaneously, buffering the maximum impact of the heel area better, reducing the peak loading rate and the peak loading rate of the ground impact at the ground stage and reducing the injury risk of the musculoskeletal system of the lower limb. The support plate 2 extending obliquely downwards can also gradually increase the rigidity from the grounding period to the supporting period, reduce the transitional deformation of materials and shorten the transitional time.
