Flat Feet (Hypermobility and Hyperpronation)


Flat feet, meaning no arches in the feet, is quite common and frequently needs no attention from a doctor, depending upon the cause of the condition. Many people with flat feet have no pain or any other symptoms related to the condition.

The arches in your feet actually develop during childhood. For some, the arches do not develop properly. Hypermobility, also known as low muscle tone, in a child can lead to flat feet, the ankles angling outward, and pain in the ankles and feet.


In other cases, a person’s arches may flatten as a result of an injury or because of the wear that comes with age. The weakening due to age and use of the tendon that supports the arch is called posterior tibial tendon dysfunction (PTTD). Click here for more information about this condition.


Broken bones and other foot injuries, as well as arthritis also can cause fallen arches and flat feet.


When flat feet contribute to hyperpronation, the turning in of the ankle bone while the rest of the foot turns out, it often leads to pain in the feet, ankles, legs and lower back. Symptoms can range from tired feet to swelling and severe pain in the feet. Because the legs are ultimately out of alignment, pain can occur in the knees and hips as well. Those suffering from hyperpronation may also experience plantar fasciitis, heel spurs and bunions.


Those who are obese or have rheumatoid arthritis or diabetes are at greater risk of developing flat feet.
