Dr. William Knudson often sees patients with fallen arches in his Leesburg, Virginia podiatric practice. In some cases, the damage is a result of poor footwear or long-term damage to the foot. But as Dr. William Knudson tells these patients, in some cases the cause of flat feet is genetic. Whatever the cause, Dr. William Knudson advises that patients take measures to correct improper arch support. Failure to do so, Dr. William Knudson says, can result in ongoing health problems. Today, Dr. William Knudson speaks with Interviewing Experts about flat feet—the causes and the best methods of treatment.
