Have a pair with around 6-10 days of use that I decided are a half size too small. Great boots that climb rock and ice surprisingly well for how light weight they are. These are the best weight to climbing perfomance three season boot out there right now imo (I prefer these to the aequillibriums and they are much lighter).
