Ordered this sandal in a size 10 for my daughter. The shoe runs at least a full size too small. I wear an 8.5 or 9 and these fit me. The bottom of the sandal feels heavy, especially compared to the flimsy leather upper that is so thin it doesn't stay up on it's own (you can't just slip this sandal on because you have to lift up the leather to slide your foot underneath it). These are going back.
