I purchased the Brownings and a pair of Carhartt Men's Artic Wool Heavy Boot Socks, Heather Grey, X-Large to compare. I really like both socks, but the Brownings are the standouts for warmth and fit. I have a size 12 foot, so I'm right on the border for the x-large size. Forced to choose, I will take a sock that is a little large than one that is a little small. These work for that decision. They fit great in a boot and just wearing around the house. Just what the doctor ordered for cold winter days.
