Although it might look like your regular sandal, the makers of FitFlop say this sandal was designed to be a workout while you walk. The idea is that the rubber sole of the sandal helps tone your legs because it creates instability during walking, which forces your leg muscles to work harder to maintain posture and balance. They come in different style from sequins, suede to bright colors and range from about $50 to $60. Did any of you try them out this summer? Do you think they actually work?
