Built from a specialized multi-polymer fabric, our 9"Socks are an integral part of the Shock Mitigation System® and incorporate multiple zones of compression that work in tandem with 5.11 Tactical Boots. An extended length integrates with full-sized 5.11 boots, enhanced padding at the sole creates a layer of cushion for all day comfort, moisture wicking technology keeps your feet cool and dry, and a tapered design reduces fabric thickness at the calf to maximize breathability.
