Ballet flats, Flip Flops, Sandals: Bad for Your Feet?
When you're seriously walking for longer than 10-15 minutes, skip the flats, sandals, and flip-flops because they offer zero support. The best shoes for walking are lightweight 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, or deformities like bunions, or hammertoes. Ouch!
