These are crocheted room shoes. They are thick and warm. My feet get cold, so I wear them over socks. It's convenient that I don't have to take them off in a Japanese-style room (^-^)v They feel good to wear after a bath, too ҉( ꈍᴗꈍ) I gave a pair to a friend last season, and they were very well-received, so I decided to list them. Please understand that these are handmade items. Recommended for those with foot sizes around 23.5cm. Since they are made of yarn, there is some flexibility. They will be shipped compressed.
