Thank you for looking! These are handmade, comfortable on bare feet, and made of cotton fabric, making them healthy handmade cloth zori sandals. (´︶` ) 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 foot as you wear them. You can tighten or loosen the thong yourself. Pull the front thong on the underside and retie it. We recommend using them tight at first. They can be machine washed in a laundry net. The color may look different from the actual product. Please understand (。>人<。) #ClothZori #ClothSandals #RoomShoes #Slippers
