Tactical boot socks average 13 in. from heel to cuff - expect them to rise just to the top of a basic 8 in. military combat boot.
A performance fit means no slipping, no bunching, no blisters - so you can focus on your mission and not your feet.
Berry Amendment compliant tactical socks are knit with Merino Wool that's raised, sourced, and produced in the USA.
US Air Force Safe to Fly certified, meeting Flame Resistant and No Melt No Drip requirements for wearing next to skin under approved flame resistant combat and utility uniforms.
A military-grade fiber, Merino Wool protects foot health and is ultra-durable in the toughest conditions.
Heavyweight socks hold heat and are breathable and padded for full protection in cold weather.
The “still” in Still Made in Vermont, USA is personal. We knit all our socks at our VT-based Mills - we can't imagine it any other way.
Unconditionally Guaranteed for Life - if these aren’t the longest lasting socks you’ve ever owned, return them for another pair.
