The ideal thermal socks for those seeking medium-level cushioning, as it’s only where you need it: through the shins and footbed (aka the spots that make the most contact with your boots). Plus, they have all our comfort must-haves—like strategic ventilation, Stay-Up Technology, and built-in arch support—and are made from a 55% Merino Wool Blend for dual warmth and sweat-wicking power.
