Thank you for looking! This is for men and is about 10cm wide. It feels good on bare feet and is made of 100% cotton, handmade cloth zori that is also 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 using a laundry net. #ClothZori #ClothSandals #RoomShoes #Slippers
