I just got these boots today and went out into the cold pouring rain to run errands in them. I walked in the pouring rain and not once did my feet get wet or cold during the day. The boots were comfortable to walk in and kept my feet warm without making them sweat. I was out for more than 5 hours in the elements with these boots on. The boots do run slightly big but that is okay for me because during the cold months I usually wear 2 pair of socks especially when I up north (I live in GA) to visit.
