Flat foot stems from a sagging in the arch of the foot and heel. In children, this will typically self-correct as they grow. When it persists or develops in adults it can be painful, and at times leads to severe pain, as well as repercussions due to a progressive increase in the deformity.
Painful flat feet vary in their severity and require a detailed clinical and radiological evaluation to determine the cause.
Custom orthopaedic insoles may sometimes be sufficient to relieve pain. Surgery tailored to each individual condition may be required when conservative treatment has failed.
