I LOVE these boots. I haven't had much time in the snow with them yet, because I got them at the end of last season. But I live in Colorado and go skiing every weekend, so far they have not disappointed. They are VERY warm, sometimes a little too warm if that is possible. They do have removable liners, but without the liners they are not comfortable and are way too big. I am normally a size 8.5 or 9 but I purchased a size 10 and they fit perfectly with the liner in.

The only down side: The boot is very sturdy and it actually can make it somewhat difficult to drive because the sole/foot/ankle does not bend.
