Familiarity: I've put it through the wringer
I use these boots when I am snowboard instructing. They are softer than the ZF1 in flex. Nike are just a comfortable boot over all. You need to half a size up from shoe size and they run slightly narrow. Good for park, hard to really ride big mtn or crank carves in, a little to much flex. Very comfortable overall I can spend the whole day in them. On days off. A wear the ZF1. Better all mtn boot and you can rip most anything in them.
