Even at $5.25, I returned these flip-flops. They may be adequate for the gym, but they offered very little support and were an extremely uncomfortable fit at the toe. I'm also not a fan of the rubber thong. Other than the Speedo name, there's very little differentiating these from the cheap rubber flip-flops you get for half the price at Old Navy. I'm a size 11/12 shoe and the size 12 flip-flop was extremely snug and uncomfortable - definitely order a size up.
