The difference between a flat foot and a normal foot:
1. The difference of the arch of the foot is to see whether the inner edge of the foot is arched. Flat feet have no arch structure, which has a poor effect on foot cushioning and blood vessel protection. The sole of a normal foot has an arch structure, which is composed of phalanges, ligaments and some tendons, which can cushion the rebound force on the ground, thus protecting the blood vessels of the sole and avoiding oppression.
2. Walking is different. After walking flat feet for a long time or standing for a long time, there will be pain in the soles of the feet and swelling of the ankles, while normal feet will generally not hurt when walking or standing.
the problem of children's flat feet must be corrected in time, otherwise it will have an impact on their later life. The discomfort can be relieved by correcting shoes or insoles, and the arch can be supported. However, if the situation is aggravated, the arch can be reconstructed through surgery.
