Study: Flip-flops can lead to health problems

A study released by the American College of Sports Medicine shows the way we walk in flip-flops may be the reason for some of our aches and pains. That's because the foot has to work harder not just to walk, but to keep the flip-flop on the foot.

The average person takes 10,000 to 20,000 steps a day. Podiatrists say the wrong footwear can cause tendonitis, lower leg, knee, hip and back problems.
