In people who have flat feet, usually both feet are affected. Everyone is born with flat feet, but as we age, the foot normally develops an arch. By age ten, most children have developed a normally arched foot. When flat feet develop later in life, they are called fallen arches.
Symptoms caused by flat feet vary widely.
Many people with flat feet have no symptoms at all, while others experience persistent foot pain, making it difficult to wear normal shoes comfortably. However, some people with flat feet feel pain with just normal activity. Flat feet that are not causing any discomfort are not serious and do not require a special trip to the doctor. However, if flat feet are causing persistent foot pain or chronic discomfort in the hips, legs, or knees, a doctor should be consulted. For severe symptoms of flat feet, other treatments may be prescribed.
