The Tweeds are part of our new Weekender line, our collection of casual socks. This is a Donegal-style sock knit with a multi-colored nub, giving it a very unique and stylish look. With a wider rib and heavier weight merino wool, the Tweeds are perfect for formal and casual wear, including boots. High denier spandex prevents the socks from slipping and bunching, while our reinforced heel and toe ensure durability. Finally, the socks are finished with a flat toe seem for supreme comfort. As with all Boardroom socks, the Tweeds are proudly knit here in the United States using only the finest materials. Available in a variety of colors. Shoe sizes 8-12. 51% Merino Wool, 24% Acrylic, 17% Nylon, 6% Polyester, 2% Spandex. Knit in the USA. Machine wash warm, tumble dry low.
