I wanted to love these...
...but it just didn't work out between us.
I would definitely suggest trying them on before purchasing. The stiffness is completely awesome, responsive and bully.
The fit is good -- tight on the heel, solid around the ankle. But the toes are where I ran into trouble.
Maybe it's Burton's Shrinkage Tech or whatever, but I got these in a 13 -- which I normally wear -- and after a full day on the mountain, my toes felt like they were being squeezed in a vice. It was excruciating. I couldn't walk once I got to the lodge. I would have traded for a size up, but I got them on clearance and they were out of 14s.
So, great boot if you get the right size, I guess. Just beware.
