Flat feet, or pes planus “fallen arches”, are where your feet press flat on the ground; and can cause pain when you do significant or extensive physical activity. Its normal in infants and usually disappears as children age and the ligaments and tendons in the foot and leg tighten. Having flat feet as a child is not usually serious, but it can last through adulthood.
In some cases, flat feet are caused by injuries or illness, creating problems with walking, running or standing for long periods.
Treatments for flat feet may include orthotics, to support your feet. For children, a podiatrist may prescribe special shoes or heel cups until their feet are fully formed.
