Thank you for looking! These are handmade cloth zori, made with cotton fabric that feels good on bare feet and is also healthy. (´︶` ) The finished size is different from shoes, so it's okay if they're not a perfect fit. They will conform to the shape of your feet as you wear them. You can tighten or loosen the thong yourself. Pull the front string on the back and retie it. We recommend using them tight at first. They can be washed in the washing machine using a laundry net. #ClothZori #ClothSandals #RoomShoes #Slippers
