Size M. According to the official size chart, it's equivalent to 23.5cm, but it's a bit too big for me, so I'm selling it. I wore them once outside, but other than that, they're in good condition. There's a slight scuff on the underside of the toe. Please note that there may be some oversights due to my personal storage. The following is the official product comment: Classic patent leather loafers. The rounded, heavy silhouette is trendy and easy to match. Despite their appearance, they are lightweight and very comfortable to wear, and the rounded toe is a key point as it prevents them from looking too cool. *Please check the quality label attached to the product for handling instructions. *This product is handled by B.C STOCK.
