the connecting portion 112 has a protruding portion provided on an edge thereof, which extends in the width direction of the upper 1 and is bent toward the ankle.
Also to be described is: the initial state of the energy storage structure 11 can be adjusted according to different movement types. When the running and jumping times are low, the items of single running and jumping and bursting force (such as 100m sprinting, high jump, long jump and the like) are relatively examined, the initial state of the energy storage structure 11 is more straight, and at the moment, the initial state of the energy storage structure 11 is more attached to the foot condition when the foot is plantarflexed, so that larger elastic deformation can be obtained when the dorsum of the foot is flexed, and more elastic potential energy is stored; when running and jumping times are more and endurance is more needed (such as marathon, etc.), the initial state of the energy storage structure 11 is more attached to the normal state of the foot of the wearer, so as to avoid excessively increasing fatigue of the athlete, and the physical strength of the second-half athlete is insufficient; the toe is upward, and the angle between the foot and the shank 4 is less than 90 degrees, called dorsiflexion; conversely, the toe is downward, the angle between the foot and the lower leg 4 is more than 90 degrees, called plantarflexion; the foot normal condition is an angle of 90 ° between the foot and the lower leg 4.

In other possible embodiments, the first covering portion 111 includes a first covering area, a second covering area, and a third covering area that are sequentially connected;
the second covering part 113 includes a fourth covering area, a fifth covering area, and a sixth covering area, which are sequentially connected;

Specifically, the energy storage structure 11 changes during the normal state of the wearer's foot, dorsiflexion and plantarflexion interconversions: when the foot of the wearer is converted from the normal state to the instep Qu Shi, the energy storage structure 11 moves along with the foot of the wearer, and at this time, the included angle between the first covering portion 111 and the second covering portion 113 is continuously reduced; when the foot of the wearer is converted from dorsiflexion to plantarflexion, the energy storage structure 11 moves along with the foot of the wearer, and the included angle between the first cover portion 111 and the second cover portion 113 increases continuously.
Specifically, the energy storage structure 11 is curved in a direction consistent with the bending direction formed by the instep 3 and the lower leg 4 of the wearer during the elastic deformation.
Further, the energy storage structure 11 can be varied with the angle between the wearer's instep 3 and lower leg 4, in which case the curvature of the energy storage structure 11 is also varied; the bending change degree of the energy storage structure 11 is consistent with the change of the angle between the instep 3 and the lower leg 4, and the filling member is fitted with the instep 3, the ankle and the lower leg 4 of the wearer in real time;
that is, when the angle between the instep 3 and the lower leg 4 of the wearer changes, the filler is deformed at the same time, the shape of one side of the filler facing the wearer continuously changes with the angle between the instep 3 and the lower leg 4 of the wearer, and the curved surface formed by one side of the filler facing the wearer is matched with the curved surface formed by the corresponding instep 3, ankle and lower leg 4 of the wearer, thereby improving the comfort of the shoe in the present embodiment.
When the angle between the instep 3 and the calf 4 of the wearer changes, the energy storage structure 11 also elastically deforms, and the shape of one side of the filling member facing the energy storage structure 11 changes continuously along with the elastic deformation of the energy storage structure 11; and the curved surface formed by the filling member facing one side of the energy storage structure 11 is matched with the curved surface formed by one side of the energy storage structure 11.
Specifically, when the wearer's foot is in dorsiflexion, the energy storage structure 11 forms a first curved surface along the length direction that is adapted to the wearer's instep 3, ankle and lower leg 4, the degree of curvature of the first curved surface corresponding to the degree of curvature between the wearer's instep 3 and lower leg 4;
when the foot of the wearer is in plantarflexion, the energy storage structure 11 forms a second curved surface along the length direction, which matches the instep 3, ankle and lower leg 4 of the wearer, the degree of curvature of the second curved surface corresponding to the degree of curvature between the instep 3 and lower leg 4 of the wearer; wherein the degree of curvature of the first curved surface is greater than the degree of curvature of the second curved surface.
In some possible embodiments, at least one of the first cover part 112 and the second cover part 113 is a structure having a thick middle and thin ends along the length direction.
In some possible embodiments, the bending strength of the second cover portion 113 is greater than the bending strength of the first cover portion 112 in the length direction.
In some possible embodiments, the bending stiffness of the energy storage structure 11 is 55N/mm-450N/mm.
Specifically, the bending stiffness of the energy storage structure 11 may be adjusted according to the sex and the characteristics of the movement. The female muscle strength is relatively weak in terms of sex, so that the energy storage structure 11 for women's shoes is relatively low in bending stiffness and is more easily bent. In sports, the energy storage structure 11 has lower bending rigidity for the sports items (such as marathons) with more running and jumping times and more endurance requirements, so as not to excessively increase fatigue of athletes, and the physical strength of the athletes in the second half of the competition is insufficient. The main purpose of the energy storage structure 11 is to recover energy and reduce physical waste. In the case of a lower number of running and jumping actions, the items of single running and jumping explosive force (such as 100m sprinting, high jump, long jump, etc.) are examined relatively, and the bending stiffness of the energy storage structure 11 can be set relatively high so as to maximally increase the effective energy output of the athlete in single running and jumping, thereby improving the performance.
In some possible embodiments, the bending stiffness of the first cover part 111 is 55-120N/mm, the bending stiffness of the connecting part 112 is 80-170N/mm, and the bending stiffness of the second cover part 113 is 120-250N/mm.
In some possible embodiments, the energy storage structure 11 has a width of 6cm-10cm.

In some possible embodiments, sole 2 comprises a first layer of sole, a rigid plate and a second layer of sole, arranged in sequence from top to bottom;
the rigid plate comprises a half sole part and a heel part, one end of the half sole part is connected with one end of the heel part to form the rigid plate arranged along the length direction of the sole 2;
the forefoot portion extends with curvature from the wearer's toes to the front end of the wearer's arch, and the heel portion extends from the wearer's heel to the forefoot portion, the forefoot portion and/or the heel portion having an angle of inclination in the lateral direction.
In other possible embodiments, the upper surface of the first sole is adjacent to the foot of the wearer and the lower surface of the second sole is adjacent to the ground; the outline shapes of the first layer bottom and the second layer bottom are basically consistent, the surfaces can cover foot projection, the first layer bottom and the second layer bottom are of sheet structures and are bonded together through edges, and the first layer bottom and the second layer bottom are elastic nylon foaming components, so that the sports shoes in the embodiment have the characteristics of good rebound ability, compression resistance, lower density and the like, and a wearer wears the sports shoes in the embodiment more comfortably and easily.
Specifically, the rigid plate has high rigidity and high toughness, and is a carbon plate or a carbon sheet; the rigid plate is of a spoon-shaped three-dimensional structure with a lower front part and a higher rear part; the half sole part has a certain inclination angle in the transverse direction, and the heel part can be horizontal or inclined in the transverse direction; or the half sole part does not have an inclination angle, and the rear heel part transversely has an inclination angle. Therefore, the rigid plate in the application is designed to have a certain radian drop shape according to the force characteristics of foot transition during running, so that the transitional benefit of exercise is improved, the foot of a wearer is protected by arranging the elastic first layer bottom and the elastic second layer bottom, and the problem that the foot of the wearer is easy to fatigue and even damage due to the fact that the sole of the wearer receives larger force in the rapid rebound process during the plantar flexion of the foot stepped by the wearer is avoided; it can be seen that the sole 2 improves the comfort of the wearer.
