One of the elastic members 2 in the accommodating space 111 at the rear sole is located at the center of the accommodating space 111, and the remaining elastic members 2 are spaced apart in the circumferential direction of the accommodating space 111. When the sole is stressed in the motion process, the middle sole body 1 receives force in the vertical direction to generate deformation in the vertical direction, when the middle sole body 1 is compressed to a certain extent, the elastic piece 2 starts to be stressed and compressed to absorb acting force in the vertical direction, and the double shock absorption effect is achieved by combining the middle sole body 1 with the elastic piece 2, and the shock absorption effect is obvious. Simultaneously accommodation space also provides deformation space (horizontal direction and vertical direction's deformation all can) for the spring, and the shear force of horizontal direction can be alleviateed in spring horizontal direction's deformation, reduces the sports injury, plays the knee-pad effect.

as shown in fig. 4, the present embodiment is different from the first embodiment in that:

the midsole body 1 has four accommodation spaces 111, four accommodation spaces 111 having rectangular cross sections are provided at intervals corresponding to the forefoot portion of the human foot, and the four accommodation spaces 111 are provided at intervals along the length direction of the midsole body 1. The rear sole portion is not provided with the accommodation space 111 and the elastic member 2. The accommodation space 111 penetrates the midsole body 1 in the width direction of the midsole body 1. The midsole body 1 has at least one follower body 11, the follower body 11 including an accommodation space 111 and a follower portion 112, the follower portion 112 being distributed adjacent to the accommodation space 111 such that the follower portion 112 has a space inclined toward the peripheral accommodation space 111; in this embodiment, the follower 112 is disposed perpendicular to the midsole body 1, and when the sole is subjected to force during movement, the follower 112 is inclined toward the peripheral accommodating space 111 along the force direction by the impact force.

Not only the midsole body 1 itself can be vertically compressed and released, but also the follower 112 can be laterally deformed and buffered, effectively dividing the impact force. Compared with the first embodiment, the shock absorption device has the advantages that on the premise of original two types of shock absorption, the shock absorption mode of the other type is added, and the shock absorption performance is further improved by combining the three modes, namely, the shock absorption mode can absorb the impact force in the vertical direction and the horizontal direction.

When the foot touches the ground to be fully stressed, the follower 112 is inclined in the stressed direction according to the acting force.

In the gait of heel strike, when no force is applied, the follower 112 and the elastic member 2 are in the vertical direction, when the foot touches the ground, the follower 112 and the elastic member 2 receive a force transiting from the heel to the forefoot, and along the force applied direction, the follower 112 and the elastic member 2 start to tilt toward the toe or the forefoot, and when the foot is fully applied, the follower 112 and the elastic member 2 tilt forward, and when the foot leaves the ground, the follower 112 and the elastic member 2 resume the vertical direction.

In the gait in which the forefoot is on the ground, when no force is applied, the follower 112 and the elastic member 2 are in the vertical direction, and when the foot touches the ground, the follower 112 and the elastic member 2 receive the force of the transition of the forefoot to the heel direction, and along the force applied direction, the follower 112 and the elastic member 2 start to tilt in the heel or heel direction, and when the foot is fully applied, the follower 112 and the elastic member 2 tilt backward, and when the foot leaves the ground, the follower 112 and the elastic member 2 resume the vertical direction.

The kinematic principle shows that the faster the speed is, the larger the impact force received by the foot when the foot touches the ground is, the more the following part 112 and the elastic piece 2 deform and incline more severely, so that the impact force can be absorbed and/or equally divided more forcefully, and obvious damping effect and the effect of reducing sports injury are generated.

as shown in fig. 7, the present embodiment differs from the fourth embodiment in that:

the elastic piece 2 and the middle sole body 1 are obliquely arranged, the inclination angle between the elastic piece 2 and the middle sole body 1 is 45 degrees, and the elastic piece 2 is inclined towards one side far away from the toes of the human body. By this arrangement, the force applied to the elastic member 2 due to the deformation of the follower 112 can be absorbed more effectively, and the shear force in the horizontal direction can be reduced as well, thereby further improving the shock absorbing effect.

Example six:

as shown in fig. 8, the present embodiment differs from the first embodiment in that:

the accommodation space 111 is provided on the lower surface of the midsole body 1.

Embodiment seven:

as shown in fig. 9, this embodiment differs from the first embodiment in that:

the accommodating space 111 is internally provided with the filler 4, and the elastic piece 2 is prevented from being excessively bent by a certain limiting effect on the elastic piece 2 through the arrangement of the filler 4. The filler 4 is a high-elasticity foaming material, has elasticity relative to the middle sole body 1, can absorb impact force better, and can improve the support and stability of the sole relative to the condition without filling.

Example eight:

as shown in fig. 10, the present embodiment differs from the third embodiment in that:

the side of the follower 112 near the toe of the human body is inclined by 70-80 degrees, namely, the follower 112 forms an included angle of 70-80 degrees with the side facing the toe of the human body in the horizontal direction.

In this gait, the inclined structure is more beneficial to the inclined deformation of the follower 112 when the midsole is stressed, further achieving the effect of buffering and reducing the horizontal force.

Similarly, in other embodiments, the follower 112 may be inclined toward the shoe tail. The arrangement of the elastic member 2 inclined toward the shoe tail direction is more suitable for the gait of the forefoot on the ground than the arrangement of the elastic member 2 vertically. In this gait, the inclined structure is more beneficial to the inclined deformation of the follower 112 when the midsole is stressed, further achieving the effect of buffering and reducing the horizontal force.
