Flatfoot (pes planus)
Flatfoot (pes planus) is a condition in which the longitudinal arch in the foot, which runs lengthwise along the sole of the foot, has not developed normally and is lowered or flattened out. One foot or both feet may be affected.
What causes flatfoot?
Flatfoot may be an inherited condition or may be caused by an injury or condition such as rheumatoid arthritis, stroke, or diabetes.
How is it treated?
Treatment in adults generally consists of wearing spacious, comfortable shoes with good arch support. Your doctor may recommend padding for the heel (heel cup) or orthotic shoe devices, which are molded pieces of rubber, leather, metal, plastic, or other synthetic material that are inserted into a shoe. They balance the foot in a neutral position and cushion the foot from excessive pounding.
