A flatfoot is a common condition of the foot’s structure. Before a baby begins walking, his feet are flat and smooth on the bottom. Over time the child stands on his toes and exercises his foot through walking and jumping motions.
The arch continues to develop throughout childhood, and by adulthood most people have developed normal arches. If a child’s foot does not develop normally by 8 years of age, it may be time to seek medical attention.
Custom arch supports (Orthotics) for kids can help support the joints so that they can finish developing. Painless flat feet are sometimes generic and are not a problem. When flatfoot occures in adulthood, it is commonly referred to as "fallen arches."
