I bought these and only tried them on indoors! I usually wear 23cm, but these fit perfectly with thin socks. The inside is fluffy, warm, and smooth (^ー^) They're soft and not stiff, so they're gentle on your feet (*´∇｀) They're light♪ They have a platform sole, so you can add some height (lol) I'm sorry, but the price is as is (・・;)
