Flat feet is a condition which is also called fallen arches. It is a complex deformity and occurs when the entire sole is in near contact with the ground while standing, that is, there is no arch to the foot. Treatment for flatfeet and fallen arches depends on the severity of the condition. If the person with flatfeet doesn't experience any pain, then treatment is probably not needed. But in other cases, it is best to consult the doctor.
