Essentially brand new pair of On Cloudmonster running shoes! I bought these a couple months back and wore them no more than 3 times before deciding I wanted a darker color. As you can see by the pictures, there is no obvious wear on the shoes themselves, and only slight discoloration on the soles (but apart from discoloration, the soles look brand new!).
