When standing, most people have a gap under the arch of their foot. Flat feet, or pes planus is the term used to describe collapsed arches, meaning that the entire sole of the foot rests partially or completely on the ground. A simple way to check to see if you have flat feet is to wet your feet and step onto a dry, flat surface. Step away from your footprint; if you see a complete footprint, you more than likely have flat feet. If you only see toes, the pads of your feet, and your heels, you probably do not have flat feet. People who have flat feet usually roll their feet over to the inner side when they walk. The feet may even appear to point outward because of this movement. In most cases, the condition cannot be prevented.
Most commonly fallen arches in adulthood can arise due to Posterior Tibial Tendon Dysfunction (PTTD). The posterior tibial tendon plays a pivotal role in holding up the arch of the foot, damage to this tendon results in the arch collapsing. Another cause of acquired flat feet in adulthood may be due to Rheumatoid arthritis as this disease attacks the bone, cartilage and ligaments in the foot causing it to change shape and flatten. Injury to the ligament, fracture and/or dislocation of the bones in the mid foot can all lead to a flat foot deformity. Adult acquired flat fleet can also arise in people who have diabetes or a neurological condition which limits normal feeling in the foot, the muscles in feet switch off, the tendons and ligaments weaken, and the arch eventually collapses.
Having flat feet can be painless and is actually normal in some people. But others with flat feet experience pain in the heel or arch area, difficulty standing on tiptoe, or have swelling along the inside of the ankle. They may also experience pain after standing for long periods of time or playing sports. Some back problems can also be attributed to flat feet.
An examination of the foot is enough for the health care provider to diagnose flat foot. However, the cause must be determined. If an arch develops when the patient stands on his or her toes, the flat foot is called flexible and no treatment or further work-up is necessary. If there is pain associated with the foot or if the arch does not develop with toe-standing, x-rays are necessary. If a tarsal coalition is suspected, a CT scan is often ordered. If a posterior tibial tendon injury is suspected, your health care provider may recommend an MRI.
arch support for flat feet
Non Surgical Treatment
Get shoes made for walking or running. One way to support your arch is to wear good-quality running or walking shoes, says Dr. Gastwirth. "These shoes generally provide good support to the foot." Add support. The top-of-the-line arch support is an orthotic insole, which may cost $900 or more and must be custom-made. "But many people with sore arches will get relief with over-the-counter arch supports for about $10," suggests Judith Smith, M.D., assistant professor of orthopedic surgery at Emory University School of Medicine in Atlanta. "The thing to remember about arch supports is that your shoe must have enough depth to accommodate them. Otherwise, you'll get a lot of rubbing on the top of your foot, or your heel will come out of the shoe." Most mens shoes are deep enough to accommodate the insoles; women should take their shoes with them to the drugstore when buying the insoles to ensure a good fit. If your heels are high, keep them wide. High heels may be your Achilles' heel--especially if you wear them constantly. "Flatter shoes are no doubt better," says Dr. Sanfilippo. Flat heels help prevent fallen arches and are kinder to your feet if fallen arches have already occurred. "If you must wear high heels, choose styles with a wide heel. Stay away from stiletto heels."
This is rare and usually only offered if patients have significant abnormalities in their bones or muscles. Treatments include joint fusion, reshaping the bones in the foot, and occasionally moving around tendons in the foot to help balance out the stresses (called tendon transfer).
