1. Shock absorption effect:
Refers to the effect that the sole absorbs the impact shock when the foot touches the ground. For example, air cushion, PU, MD, EVA, etc. all have shockproof function, especially air cushion is generally valued by people. When people's feet fall to the ground, the impact force of the ground on people's feet is usually 2-3 times that of the human body, especially when bouncing, which can be as high as 10 times. A good shock-proof device can reduce this impact force. When the soles of the feet fall to the ground, it can disperse the impact force through deformation to achieve the effect of shock absorption. Thereby avoiding the damage caused by excessive vibration. 2. Torsion system:When the athlete turns, turns back and moves sideways, different parts of the foot will twist in different directions, which is easy to cause sports sprain. Install a device on the inner side of the foot and the arch of the foot with high-density materials to prevent the foot from turning inward too much during exercise and avoid sports sprain.
