Description

Sports shoes with functions of foot guidance and forefoot rebound and sole thereof

technical field

The utility model relates to sports shoes, in particular to a sports shoe with the functions of foot guidance and forefoot rebound and the sole thereof.

Through long-term research on the foot movement characteristics of runners, it is found that when running, the foot touches the ground mainly includes two ways: the front foot touches the ground first and the rear foot touches the ground first, and it is subdivided into the following ways according to the different running speeds : When jogging, most people touch the ground with their heels first, then transition to the midfoot and forefoot in turn, and finally kick off the ground through the forefoot and big toe, while a small number of people touch the ground with the midfoot and forefoot first When running fast, most people touch the ground with their midfoot and forefoot first, and a small number of people touch the ground with their heels first; when running long distances, it is a combination of the above two ways of touching the ground.

Through laboratory tests, it is found that the ground contact time of the forefoot and midfoot is about half of that of the heel first, and when the forefoot and midfoot touch the ground first, the gravitational potential energy accumulated in the arch of the foot and the forefoot can be It is transformed into elastic potential energy, thereby improving the rebound of the foot, promoting the return of foot energy, and greatly reducing energy loss compared with the way that the heel first touches the ground. Therefore, in competitive competitions, the performance of players who land on the forefoot and midfoot first is often better than that of players who land on the heel first. However, the running style in which the forefoot and midfoot touch the ground first will cause the arch of the foot to bear a greater impact when landing, which will cause fatigue damage to the forefoot and midfoot.
