Flat feet is a condition in which the foot does not have a normal arch when standing.
A common and usually painless condition, flat feet may occur when the arches don’t develop during childhood. In other cases, flat feet may develop after an injury or from the simple wear-and-tear stresses of age.
Flat feet can sometimes contribute to problems in your ankles and knees because the condition can alter optimal alignment of your legs. If you aren’t experiencing any pain, no treatment is necessary.
Anatomy
The anatomy of the foot is very complex. When everything works together, the foot functions correctly. When one part becomes damaged, it can affect every other part of the foot and lead to problems. With a flat foot deformity, bones, ligaments, and muscles are all affected. A combination of malalignments results in the flatfoot appearance.
