Flat Feet
Flat feet, or fallen arches, is a condition in which little or no arch is formed at the bottom of the foot, thus causing the feet to rest flat on the ground. Flat feet can be an inherited condition or an acquired condition that develops over time.
A flat foot (or feet) can limit activities for some people, while others experience no difficulties. If left untreated, a flat foot can lead to excessive pronation of the feet, which can cause bunions, heel pain, hammertoes, shin splints, knee, and hip and back pain.
