My foot size is 24cm, but when I wear 24cm geta, my heel sticks out. So, I think 23cm would be better... Also, it's almost unused. Comes with a box. This item was stored in a closet, and since I no longer wear yukata, I'm selling it. Traditional geta with red thongs and a wooden sole. - Color: Red thongs - Material: Wood - Sole Design: Non-slip - Design: Traditional Japanese footwear style - Size: Standard size Thank you for looking.
