Our merino wool collection is a staple for the professional man's wardrobe. Featuring solid colors knit with a vertical rib, these socks are appropriate for both formal and casual settings. Merino wool is a soft, natural fiber that enables your feet to breathe, providing daylong comfort in warm and cool weather. The over the calf length prevents professional men from committing the faux pas of revealing skin when crossing their legs. The top band of the socks is designed with just the right amount of high strength spandex, ensuring that the socks remain up on your leg throughout the work day while still providing a comfortable fit. As with all Boardroom Socks, the merino wool collection is knit in the United States using the world's finest yarns. Available colors are black, dark brown, midnight navy, grey heather, khaki and charcoal. Save with Our 3 Pair Set. Shoe sizes 8-12. 67% Merino Wool, 30% Nylon, 3% Spandex. Machine wash warm, tumble dry low.
