The Darn Tough Men's Westerner Over-the-Calf Lightweight Work Sock is built for hot, demanding workdays when staying cool matters most. Designed for cowboy boots and tall work boots, this over-the-calf sock delivers breathable comfort in humid and high-heat conditions. Lightweight Merino wool helps move moisture away from the skin to keep feet dry, while terry loop cushioning underfoot and around the ankle adds protection without bulk. Rib-knit cuffs hold the sock securely in place, and reinforced Achilles cushioning improves long-term comfort during extended wear. Tough enough for hard labor, the Westerner is made to perform when the job turns up the heat.Materials: 53% Nylon, 42% Merino Wool, 5% Lycra SpandexCushionedRib-knit cuffsReinforced Achilles cushioningFit: Performance fitHeight: Over-the-CalfWeight: LightweightAverage height: 17 in. from heel to cuffSock SizeMen'sWomen'sMedium8 - 9.510 - 11.5Large10 - 1212 - 14Extra Large12.5 - 14.513.5 - 16.5
