Flat feet are a common cause of general musculoskeletal pain and problems. Your body's balance begins in the feet; when the feet do not provide proper support, it can raise your risk for joint problems caused by poor posture and unnatural gait.
Is it bad to be flat footed?
Flat feet tend to cause another condition called overpronation, which is when the ankles roll inward while you're walking. This can lead to foot and ankle pain. Because your feet are the basis of support for your entire body, having flat feet and overpronation can cause problems with your spinal alignment.
Can flat foot be cured?
In adults, flat feet usually remain permanently flat. Treatment usually addresses the symptoms rather than a cure. In adults the condition is called "acquired" flatfoot because it affects feet that at one point in time had a normal longitudinal arch. The deformity may worsen over time as one ages.
