These winter boots are great. Extremely light weight. They were quite stiff at first, but broke in after a few winter hikes. Very comfortable now. My only complaint is actually kind of serious: the top hooks catch on things too easily. I was navigating through snow on a hike and my two feet ended up right next to each other, but the metal hook on one boot caught on the metal hook of the other, and I stumbled and fell. I got very lucky, because I could have had a really, really bad fall. I now only wear these when I have clothing covering the top of the boot, as opposed to tucked in.
