…Wear it. But first make sure it’s just right. For example, a shoe that’s too loose may allow the foot to slide around, inviting blisters. “If you have peripheral neuropathy, you might not be able to feel how a shoe fits,” says Robert A. Eckles, D.P.M., clinical dean of the New York College of Podiatric Medicine and an expert on the diabetic foot. His advice: Shop at a store that specializes in medical footwear—shoes for people with conditions such as diabetes or arthritis. (Medicare has a shoe program that pays for a pair of shoes every year for people with diabetes who meet certain criteria.) If that isn’t possible, buy three pairs and have your doctor evaluate them. Choose the shoes that fit best and return the others. (Check the store’s return policy first.) Or shop at a store specializing in athletic shoes and bring a family member or friend who can objectively assess the fit for you.
