These are stretch tabi socks made of Toray nylon, size S (with 5 hooks). I bought them new and wore them once for a wedding. They have been home-cleaned. - Size: S (21.5-22.0 cm) I usually wear 22.5cm shoes, but the tabi socks were a little big even in size S. There were no problems with wearing them or how they looked. Perfect for weddings or coming-of-age ceremonies. Shipping may be done in a compact package. Thank you for your understanding.
