What are flat feet?
Flat feet is a condition in which one or both feet don’t have normal arches. At first, all babies' feet look flat because an arch hasn't formed yet. Arches should form by the time your child is 2 or 3 years of age. Flat feet, even in older children, usually do not cause any problems.
