Rothco Military Thermal Boot Sock

These G.I. Type thermal boot socks are just like those worn by active duty military personnel stationed in cold weather environments. And as such, they're proudly American made. The socks feature a heavyweight construction comprised of thick, durable cotton/nylon material designed to wear like iron. When worn in winter boots that have minimal to no insulation, you can count on these thermal socks to keep your feet toasty warm during extended periods of time spent outside in freezing conditions. Perfect for hunting, ice fishing, snow removal, or outdoor jobs like construction.
