These boots are awesome. The first time I tried them on which was at home, not on the mountain, I thought they were too small. I wore them for 3 hours. I was gonna send them back but wanted to try them on again to make sure they weren't going to work. I cut my toe nails and tried them again. They fit perfectly. I wore them for another couple of hours to continue breaking them in. The bottom line is these boots mold to your feet and they are super light compared to a lot of other boots out there. I kinda took a shot in the dark with these boots but they turned out to be a great buy. Lacing em up is a small chore but not everything is perfect.
