When you imagine thick, warm socks; these socks are what you are thinking about! Very comfortable, very warm. Order a size larger than you think you might need. They are so thick that they are a little hard to get on, but they are well worth the effort! They are "longer" than I thought and cover your entire calf but that isn't really a bad thing. And they are VERY good at keeping my diabetic feet warm in the finished basement area of my "mancave"!<G> I recommend them highly.
