I really like these boots and they do a good job of keeping my feet pretty warm (which is a tough challenge!) My only complaint was when I first got them, the foam padding under my foot would slide to one side or the other as I walked, so I was kind of stepping off of it. It was annoying for a couple days but then as I 'broke them in', the sliding stopped and my feet imprinted into the foam. Now I have a left and a right slipper (they feel weird if I swap them)! On the first day, I thought about sending them back because of this but I'm glad I didn't because it was only a temporary issue. Now I love them and am very happy.

Note that if you have white carpeting as I do, you may want to consider getting the gray ones. I got the black and they leave little bits of dark fuzzies on my white carpet. Again, less and less of this shows up over time. The first week your carpets will have fuzz everywhere but it gets better. Hope that helps!
