Review on MCTi Winter Ski Socks: Thermolite Thermal Over the Calf Long Socks for Snowboarding, Skiing, Hiking - 2 Pairs by Michael Montgomery

These seem well made and look good after several washes. These are a true medium thickness sock. The cushioning is well designed, and doesn't get bunched up putting on tight ski boots. The sizing though should be medium for US men's 9 & 10 (possibly 11 as well). I think unless your ski boots are loose fitting, the medium would bunch up on a US 8 size foot. Warmth in ski boots has more to do with the ski boot liner, than with the socks. I would say these are as warm as any of the similar thickness Merino wool socks (but without the itching or rash) that I have used in the past. I'm a ski instructor and ski four or five days a week through the winter.
