These boots are super comfy and keep your feet dry and warm in sub zero conditions. I also enjoy being able to tighten upper & lower zones separately, but it doesn't do much good when they loosen up as you ride. I'm about halfway through my second season with them and they've seen all conditions on the east and west coast. They are still super warm and fully waterproof, but I have to tighten them after every run, especially in the park. I really wanted a soft boot that would stay exactly as I set it, but this is just a soft boot that turns to mush if you do anything above an intermediate level. Disappointed and will probably try to take them back to exchange. Overall, I can't recommend them :-(.
