Only had these boots for a week, so far so good. I work outdoors in a ski resort in Vermont. The boots are warm and they seem very well made. As far as the size goes, I wear a size 13, these boots run a little big, the length is about right, I don't think a size smaller would work, they are wide, but the lining makes them fell smug. If you are between sizes I would recommend going down a size.
