My husband loves these socks! They are warm and thick enough to wear around the house.

Great for U.P. Cold

Moved to Michigan's U.P. and have been trying several different cold weather socks, but nothing from the stores seem to work below 20 degrees for me. I've tried Columbia fleece, Carhartt heavyweight wool and my toes still freeze and blister (when wearing the socks with Muck boots). So finally got desperate and looked online for better quality socks and found these. They were a bit tight in my Muck boots but surprisingly kept my toes from freezing in the below 20 temps. I plan to wear them with my new Baffin boots when the weather gets even colder but am happy that these work as good as the reviews say.

Best ever!

Love the extra cushion on the balls and heels, has helped reduce the cramping I sometimes get in my feet while doing jumping jacks and jump rope.

Socks were just as described. I work in an environment that is very cold and these socks keep my feet very warm.
