We had 18" of snow over the weekend. These boots kept me warm and dry. I was worried about driving in a snow boot, as most are very rigid. I had no problems diving in these. The ankle was flexible enough for comfortable walking and as well as driving. I followed other reviewers recommendations regarding size. I normally wear a 7.5, but ordered these a half size smaller (7) and they fit perfectly. They go on and off easily, although there is no zipper, and have great traction in slippery conditions. All in all a great purchase!
