When your mission demands performance, your socks can't be an afterthought. Fox River's Tactical Boot Lightweight Mid-Calf Military Sock is engineered for heavy use, built with 69% polypropylene, 26% nylon, 3% polyester, and 2% spandex to deliver lightweight protection, moisture control, and long-lasting durability inside any tactical or work boot. Whether you're in the field, on patrol, or putting in a full shift, these military boot socks are ready for whatever the day demands. Polypropylene's naturally hydrophobic fibers work alongside Fox River's exclusive Wick Dry technology to repel and remove moisture at the skin level, reducing hot spots, minimizing friction, and keeping feet dry and blister-free through extended wear. The URFit System provides targeted arch support and memory-knit construction that holds its shape inside your boot all day without bunching or slipping. A cushioned sole absorbs shock and insulates underfoot, while multi-filament yarn construction adds abrasion resistance and extends sock life through constant hard use. A smooth, flat comfort toe seam keeps irritation out of the picture from start to finish. 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. Lightweight, durable, and built for the mission.
