The size is listed as 26cm, but the shoes run large, so they should fit someone who normally wears 27.5-28cm. I bought these about a year ago, but I haven't had a chance to wear them, so I'm selling them. Please consider purchasing them. There are no noticeable stains on the surface, but the heels are torn. Please make sure to check the condition before purchasing. Returns and refunds are not accepted.
