Description

Technical Field

[0002] Shoes are a common tool for people to travel in daily life. Among them, important indicators for evaluating the quality of a pair of shoes include: the aesthetics of the shoes, the anti-skid performance of the shoes, the shock-absorbing performance of the shoes, etc. Among them, the anti-skid performance of the shoes is not necessarily better. When walking on some surfaces with a high friction coefficient, if the anti-skid performance of the shoes is too strong, and the user's gait is not good enough when walking, the user is prone to a sense of jamming when walking, which may cause the user to fall easily. However, if the anti-skid performance of the shoes is too poor, the user is prone to fall when walking on a slippery road. The position that affects the anti-skid performance of the sole is mainly the forefoot position on the sole, and the soles in the prior art usually do not have the function of replacing the anti-skid performance of the sole. Therefore, when users have different anti-skid requirements, they cannot be met on the same pair of shoes. Summary of the invention
