The sole is not very good for ice, and while this is a good boot for slush, in Spring, I was just outside shoveling wearing these boots, with wool socks, and my feet were cold, of course, it is 0 outside, yes, zero. I have large calves, and these boots are fine for me, even with jeans tucked in.

But, if you need a warm boot, this one is not it. However, I have a super pair of boots, that are hard to drive the car in, so, if you are running around town, doing errands, in and out, these are great boots for that, and not too heavy. But, for super cold, standing around, and icey areas, look for another  boot.
