Some duties demand more, and Fox River's Wick Dry Maximum Medium Weight Mid-Calf Boot Military Sock is built to deliver it. Made with 70% polypropylene, 28% nylon, and 2% spandex, this medium weight military boot sock combines maximum cushioning, permanent odor defense, and Fox River's exclusive Wick Dry moisture management into one high-performance package. Whether you're in the field, on the job site, or putting in a full tactical shift, these boot socks take everything your day dishes out. Polypropylene's hydrophobic fibers work alongside Wick Dry technology to rapidly draw moisture away from your skin, keeping feet dry and comfortable through hours of continuous boot wear. The URFit System delivers a personalized fit that holds its shape all day without slipping or bunching, while Scentry odor defense uses silver and copper fiber technology to stop odor at the source. No treatments needed. A fully cushioned sole and leg absorb daily impacts and insulate underfoot, and multi-filament yarn construction ensures these military socks hold up through constant hard use. A smooth, flat comfort toe seam keeps irritation completely out of the picture. Available in army green, black, coyote brown, and foliage green. Made in the USA since 1900, Fox River backs every pair with a 1-year manufacturing defect guarantee. Maximum performance, built in.
