Thank you for viewing. I'm selling these because the size didn't fit me, even though I bought them from someone else. The boots are marked as size M, so I've listed them as 23.5cm. However, the material is soft, so I was able to try them on, and I usually wear 24~24.5cm. The boots are slim, so they didn't fit me, but I think they would fit someone who is not wide-footed, even if their size is slightly different.
