I'm not sure about the size. The back says 23, but I usually wear 24.5cm or size L, and I've never been able to fit into 23cm before. But these fit perfectly. They're lace-up boots, so the fit can be adjusted, but they're stiff (made of leather?), so I think my feet would hurt if I wore them for a long time. The inside is fluorescent orange, so I think they're for work. The toe part is scuffed up т_т Please take a look. It might be better if I filled it in with a shoe pen...
