Flat feet are a normal variation of anatomical development and occours due to a loss of Inner Arch of the foot. The arch is formed by a bony support with musculature maintaining the shape of the Arch.
It is observed that children can have more incidence of a foot looking flat than adults. But, this is usually a supple flat foot. By supple flat foot we imply that the child usually has no difficulty performing all tasks of daily living which also include running, jumping, hopping etc. Parents are usually worried about the “flat looking” foot which is not a symptomatic flat foot.
