What is the best treatment for flatfoot?

To treat or not? Flat feet are, to a certain degree, a normal foot type. Many people live asymtomatcally with them. Other people, however, do develop knee, hip, and back problems because of compensations through the chain. In addition to a good core, lower body, and intrinsic foot muscle strengthening program, some benefit from orthotics.
Wide variety. Many cases of flatfoot require no treatment. Some of the best athletes in the world are flat footed and have required no treatment. Treatment is required only if problems such as foot pain, tendinitis, plantar fasciitis or knee pain develop as a result of a flat foot. Over-the-counter or custom orthotics can be utilized. Surgery is done very rarely for severe cases, particularly in children.
