Most flat feet do not cause pain or other problems.
At times, foot pain, ankle pain, or lower leg pain are present (especially in children). They should be evaluated by a health care provider.
Adults may notice some symptoms. Their feet may become achy or tired when standing for long periods of time or after playing sports.
In people with flat feet, the instep of the foot comes in contact with the ground when they stand.
The health care provider will ask you to stand on your toes. If an arch forms while you are standing on your toes, the flat foot is called flexible. No treatment or further work-up is needed.
If the arch does not form with toe-standing (caled rigid flat feet), or if there is pain, other tests may be needed, including:
