What is it?

Flat feet (also called pes planus, or fallen arches) is a condition in which the normal longitudinal arch of the foot does not function properly. The role of the longitudinal arch is to absorb the shocks occur while stepping and to distribute the body weight correctly between the bones of the foot. When this arch collapses, there is a change in the alignment of the legs, ankles and knees, in a way that can cause pain when walking or standing for long time. However, many people with flat feet do not experience pain and do not need any treatment.

Signs & symptoms

Flat feet can cause foot pain, particularly in the heel or arch area, accompanied by swelling along the inside of the ankle. Pain may worsen with activity.


A physical examination by your physician, viewing the mechanics of your feet, is usually sufficient for diagnosis. In some cases, feet X-ray may also be needed.


Treatment of flat feet may include:
- Arch supports and supportive shoes
- Physical therapy: A physiotherapist can help correct the distorted position of the ankles and legs, and improve the walking technique.
- Surgery: surgery may be an option in more serious cases and is usually the last resort.
