In the market for walking shoes? To find the right fit, try these tips: 1. Wear the same socks shopping that you'll wear when walking. 2. Make sure you have at least a half-inch between your longest toe and the end of the shoe. 3. Be sure the shoe is wide enough. The side-to-side fit of the shoe should be snug, not tight. 4. Walk a few laps in the store. Make sure your heel fits snugly in each shoe and doesn't slip as you walk.
