Functional flat feet can be treated through general treatment, other treatments and surgical treatments to alleviate the symptoms, but the specific efficacy varies from person to person. 1. General treatment: Functional flat feet are mostly caused by long-term weight-bearing standing, improper footwear and other acquired factors, and should be corrected and prevented according to the corresponding causes. For example, you can adjust the standing working time and change comfortable shoes. If prolonged walking causes pain in the medial side of the foot, rest should be taken in time and local braking treatment should be carried out. 2. Other treatments: Orthopedic insoles can be used for treatment. They can provide strong support to the arch of the foot, effectively improve the force on the bottom of the foot and cushion the shock, so that the force is evenly distributed to the heel and forefoot, reducing the pain on the bottom of the foot. 3. Surgery: Some people with severe symptoms and poor results of conservative treatment can consider orthopedic surgery. If symptoms such as foot pain occur, it is recommended to consult a doctor in time for diagnosis and treatment.
