I bought these boots thinking they would be very warm and dry for an overseas trip I was planning. They met that test, but were the bottoms (inside) were very hard - downright uncomfortable - and the zipper rubbed a hot spot just below my ankle. I tried thick socks. I tried thin socks. Nothing helped. And they did not have the traction I expected. I was walking on snow every day to watch a ski competition and they were not up to the task. I returned them.
