Flats, Flip Flops, Sandals: Bad for Your Feet?
When you're walking for longer than 10-15 minutes, skip these styles because they offer zero support. The best shoes for walking are lightweight, breathable ones with a wide, flexible space where your toes go -- the toe box. That way your toes aren't squished. Otherwise, you could end up with blisters, calluses, bunions, or hammertoes.
