Flat feet indicates that no arch is present and the underside of the foot lies completely flat on the ground. The true 'flat foot' is very rare. In fact, less than 5% of the population have flat feet with no arch present whatsoever. It is quite normal for small children to have flat feet, however the arch usually develops as they get older. If the arch hasn't developed yet by the age of 5 or 6 the child may need children's orthotics.
Over-pronation is a common biomechanical problem that occurs when the arches collapse while walking or standing. This condition hampers our natural walking pattern, causing an imbalance, and leading to wear and tear in other parts of the body with every step we take. Whether you suffer from over-pronation like most of the population, or you have a true flat foot, in both cases your poor walking pattern may contribute to a range of different complaints. As we age, poor aligment of the feet causes very common conditions such as heel pain or knee pain. Over-pronation has different causes. Obesity, pregnancy, age or repetitive pounding on a hard surface can weaken the arch, leading to over-pronation. Over-pronation is also very common with athletes, especially runners, who most of them nowadays use orthotics inside their shoes.

To give your arch the support it needs, your foot and ankle surgeon may provide you with an ankle brace or a custom orthotic device that fits into the shoe. Immobilization. Sometimes a short-leg cast or boot is worn to immobilize the foot and allow the tendon to heal, or you may need to completely avoid all weight-bearing for a while. Physical therapy. Ultrasound therapy and exercises may help rehabilitate the tendon and muscle following immobilization. Medications. Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, help reduce the pain and inflammation. Shoe modifications. Your foot and ankle surgeon may advise changes to make with your shoes and may provide special inserts designed to improve arch support.

To prevent progression, eg with a Charcot joint. Tibialis posterior dysfunction, where non-surgical treatment is unsuccessful. Possible surgical procedures include Achilles tendon lengthening. Calcaneal osteotomy, to re-align the hindfoot. Reconstruction of the tibialis posterior tendon. For severe midfoot collapse of the arch, triple arthrodesis may be indicated.
