Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] The study of sports biomechanics found that during the movement of the human foot, such as walking and running, the outside of the heel first touches the ground, and then transitions to the inside of the heel and the sole of the forefoot, and the moment the outside of the heel touches the ground has a huge impact. According to the structural characteristics of the foot, after the outer side of the heel touches the ground, it will smoothly transition to the inner side of the heel, and cooperate with the internal rotation of the ankle to buffer the momentary impulse when it hits the ground. According to the above-mentioned sports biomechanical characteristics, the present invention provides a sports shoe sole. Simulate the motion structure characteristics of the foot, make the heel rotate smoothly and control the transition internal rotation and heel stability, s...

Abstract

The invention discloses a sole of a sport shoe. A heel is provided with a wedge-shaped opening in which a damping device with a profile matched with that of the wedge-shaped opening is embedded; the damping device consists of a shock absorbing cushion pad made from a polyurethane material, a stabilizing piece made from thermoplastic polyurethane (TPU) and bearings made from TPU; the shock absorbing cushion pad is wedge-shaped; the stabilizing piece is covered on the upper surface of the shock absorbing cushion pad; and the bearings are annularly sleeved on the outer side face of the shock absorbing cushion pad. In the damping device on the sole of the sport shoe, a circle of bearings made from the TPU are annularly sleeved at the periphery of the shock absorbing cushion pad made from the polyurethane material, the shock absorbing cushion pad simulates heel fat, absorbs and buffers impact force on a foot in a moving process and realizes shock absorbing and damping functions in combination with fat on a heel part and the bearings play a role in supporting and accommodating the shock absorbing cushion pad well, so that the heel part is prevented from rotating inwards excessively, the damping function of the sport shoe is improved and the moving stability is ensured simultaneously.

Description

technical field [0001] The present invention relates to sports shoes, in particular to sports shoe soles. Background technique [0002] During exercise, the human foot is the part that is in direct contact with the ground. This part will bear the ground impact force several times the body weight. Such a huge impact force can easily cause damage to the human foot and other body parts. Therefore, Therefore, the cushioning function of sports shoes is very important in the design process of sports shoes. [0003] At present, the cushioning function of sports shoes is mainly realized by using cushioning and shock-absorbing functional materials or shock-absorbing mechanical structures. However, these designs have greatly weakened the stability of sports shoes while achieving better cushioning functions. Contents of the invention [0004] The technical problem to be solved by the invention is to solve the problem of ensuring the stability of motion while improving the cushioning...
