Review on Thermasilk Over-The-Calf Sock Liner By Terramar by Roberto Tucker

I wear these as a liner sock and have used them in very cold winter conditions down to -10 degrees Fahrenheit. Once we get down to -20 on a regular basis I'll try to remember to post an update. These socks have helped keep my feet warm without getting sweaty. Combined with an alpaca over-sock, they've kept my toes comfortable, even when snowmobiling. The fit is comfortable without being constricting. My calves are muscular but not particularly thick, and these socks stay up without inhibiting blood flow. They also do double duty in keeping the legs of my long johns from riding up. Zero itch!
