KEEN Jasper Rocks SP 25.5cm I wore these once after purchasing them. Since then, I haven't worn them, so there's no scuffing on the heels. However, the soles show signs of use, so please refrain from purchasing if you are overly concerned about this. The JP size is 25.5cm, but they fit a bit small, so they would be a good fit for someone who usually wears a 25cm size.
