I don't buy anything but Ryka shoes for athletics, because they were designed for a woman's foot: wider at the toe, narrower at the heel. This means more comfort and fewer blisters. This shoe does not disappoint. It's sturdy but fluid. It's a studio shoe, so it's best for aerobics, zumba, the gym. The sole is smoother to allow for smoother movement across the floor. You don't want to wear this shoe for anything where you want to keep from sliding.
