This is the stiffest boot I've ridden in 20 years of riding, but that in turn makes for a very responsive ride. I wouldn't say its overly stiff though. Comfy and seems well built. Although I've only ridden them a couple days
It also has a small footprint, which is a huge plus as I have size 11.5 feet and like to minimize toe drag. My previous boot was the 32 ultralight and I had to adjust the straps on my bindings to make the smaller to fit right.
Another bonus is the ease of removing the liners, as if you go into the BC and are camping you probably sleep with your liners in your sleeping bag to keep them warm.
