Used only a few times, about 5 times, and the heel soles show little wear, so I think they can still be used for a long time. There are no noticeable stains or scratches. A cushion sticker to prevent blisters was used on the heel, but it has been cleanly removed. There may be some stickiness, but in my personal opinion, I think it can be worn without being noticeable. As for the size, it's a large fit. I think it's about a 26.5-27.5 size. Although it is a beautiful item, please purchase only if you understand that it is a used item. This is a used item, so no claims and no returns are accepted.
