First of all, if people often walk on tiptoe, the center of gravity of the human body will focus on the inside of the foot. The heavier a person's weight, the greater the pressure on the inside of his foot. In the long run, it is easy to cause the medial foot to collapse. At this time, it is easy to cause flat feet, which will be rejected in the basic requirements of dancing and joining the army, so the influence of splayed feet is not small.
Secondly, people who walk or stand with splayed feet will also exert great pressure on the inside of the knee joint, leading to the deformation of the human knee joint. It is difficult to straighten the knee joint of the leg when walking, so it will affect the overall aesthetic feeling of people. When running, splayed feet will affect the running efficiency and easily cause foot injuries.
In addition, the external splayed foot may also cause serious wear on the lateral side of the knee joint, which will lead to pain on the lateral side of the knee joint after a long time.
