This item is old, but I have kept it with care. The size is listed as M, but I have set it to 23cm. I usually wear 23.5cm sneakers, and I was able to wear these without any problems. However, there are individual differences in foot shape, so the size is only a guideline. I am also selling other boots. I will offer a discount of 1,000 yen for those who purchase multiple items. I will ship the item with a bag over the box. Thank you.
