These are really nice socks at a great price. Soft, cozy, and very warm. Wore them today with temps in the 20s and windchill temp in the teens. Kept my feet nice and toasty. My feet fell "toes over heels" in love! Buying more.
This is a Christmas gift so can't review at this time but I bet it will be a 5 Star.
