Materials: Base: Cotton (total shibori) Thong: Cotton Size: 23-24.5cm (This is an estimate) Width: 9.5cm Regarding the size, this is just an estimate as the length of your toes also varies. It's not meant to fit as snugly as shoes, and it's okay if your heel extends beyond the back. In fact, it's probably better if your heel extends a bit. #IndoorShoes #BunionCare #FootHealth #Handmade #Handmade #Gift #RoomShoes
