You probably don't give much thought to the steps you take. However, walking is actually quite a complex act, especially for your feet. Because your feet support all of your weight and help you balance when you stand, they're subject to substantial pressure and risk of injury.

One common foot condition is flatfeet. If you have a flat foot, the arch on the inside of your foot is flattened. Flatfeet usually don't cause a problem. However, flatfeet can contribute to problems in your feet, ankles and knees. Simple corrective devices are available to help prevent complications of flatfeet.

Signs and symptoms 

With flatfeet, you may experience the following signs and symptoms:

• A flat look to one or both of your feet

• Uneven shoe wear and collapse of your shoe toward the inside of your flat foot

• Lower leg pain

• Pain on the inside of your ankle

• Swelling along the inside of your ankle

• Foot pain
