These shoes run VERY large. I would not say they run like typical shoe sizes, but about a half size to a full size larger. I thought I would have to send them back. However, they fit comfortably with tight fitting, thick socks. They slip off easily when you want to take them off. They are like glorified slippers that you can wear as shoes. Worn barefoot, they are much too large and come up too high on the heel so that they rub my skin uncomfortably. I do like wearing them around the house, though. Just know that they are going to fit big.
