I've been using these boots for one season now. What I like about them: They are relatively light, flex nicely for skinning, are Dynafit compatible, bright in color (in case of avalanche), and offer a good amount of warmth for anything above 10 deg C. Things I am not too keen on: For my preference, they are a little too flexy. They tend to slip slightly on the heel when going up hill. Would I buy them again? Touring boots have come a long ways in the last couple years and I think I would try something new that is more rigid and better able to keep my heel in place like the Black Diamond Boa system.
