I think it's a size M, so 23cm to 23.5cm. I've kept it at home since I bought it. I only tried it on in the store, but there are a few small stains and wrinkles. Personally, I don't think the stains are very noticeable. Please check the photos. I haven't worn them outside, so the soles are clean. There's one white spot. Please check the photos. Thank you for your understanding.
