They’re 100% authentic, purchased last summer and only worn a few times. Please look closely at the photos and detail for any signs of scuff. I re-listed these after cleaning them up more—condition reflects in the current price. This comes with one dust bag. Please refer to shoe reviews for sizing advice as this style notoriously runs narrow and small. I can approximate (not promise) that this runs closest to a US size 8. I’m between an 8-8.5 and the fit is snug with a thin sock. According to reviews, some people go up an entire size if they want to wear thick socks. Happy shopping!
