Thank you for looking! This is a slightly defective product. See the 5th photo. There is ink on the heel. It's not very noticeable, but it's a little cheaper. I hope you will purchase it if you understand. Handmade, Comfortable on bare feet, made of cotton fabric, These are handmade cloth zori, good for your health. (´︶` ) The finished size is different from shoes, so it doesn't have to be a perfect fit. It will conform to the shape of your foot as you wear it. You can tighten or loosen the thong yourself. Pull the front thong on the back and retie it. We recommend using it tight at first. You can wash it in the washing machine in a laundry net. #ClothZori #ClothSandals #RoomShoes #Slippers
