Thank you for viewing. This is a set of women's shoes. The size is listed as 23cm, but it's actually a size M. A woman who wears 23cm shoes wore these, so I believe the size is approximately that. There is no wear on the heels, and I think they can still be used, but they are used, so there are some scratches and dirt. Please check the photos and consider purchasing. Shipping will be done using recycled materials.
