5.11 Tactical's Summer Sock offers all the high-performance support and comfort end-users expect, now in a lighter, thinner, dressier model. Designed for hot weather, the sock blends 5.11's Shock Mitigation System and multiple zones of compression with summer-weight fibers for breathability. Slightly modified compression zones offer band arch support where officers need it. And, like 5.11's popular Level I and Level II socks, Summer Socks are functional and durable. The socks are constructed of strong polyester yarns that wick away moisture, plus nylon for strength, spandex for stretch and shape, as well as rubber to stay put. Available in black with a choice of 6-inch or 9-inch heights.
