All of the Warmth Without the Bulk
Known for its light feel and heavy-duty performance fibers, the ThermoThin Sock provides all of the warmth without all of the bulk. A compression band at the arch of the foot and an ultra-thin calf make this warm sock easy to slip into any boot.
Keeping it Light with Thermolite
The ThermoThin Sock's Thermolite polyester foot bed adds warmth without bulk or weight so you can stay warm without feeling uncomfortable or constricted in your boots.
A mesh panel along the top of the foot allows for added breathability, ensuring comfort even on the hottest days.
Where Comfort and Protection Meet
Added features such as an arch compression band, a perfect fit top and heel-to-toe padded protection to defend your feet against boot pinch points provide added comfort.
