The main danger of flat feet is that they are prone to fatigue or pain, which is a foot deformity. This is because the function of the arch of the foot has the role of bearing weight and cushioning the role of shock, so in the process of human movement, there is a lot of force through the arch of the foot cushioning and reduce the damage to the body. Especially in the process of running and jumping, the force on the arch of the foot is also relatively large and can effectively slow down the impact of external forces on the body, and can effectively relieve the pressure of gravity on the local. After the arch disappears, it will produce direct pressure on the tissue at the bottom of the foot, and the angle of the force line changes, making the foot more easily fatigued. However, there are a few patients with congenital flatfoot whose walking, running and jumping are not affected, but this is only a minority of people.
For the treatment of flatfoot, prevention of secondary flatfoot is very important, you can actively toe walking, flexion exercises, strengthen the exercise of the anterior and posterior tibial muscles, correct foot valgus, can wear orthopedic shoes are beneficial.
