The Greensboro Low brings the look of a no-show and the performance of a true multisport sock, with a micro-crew cut that stops chafing around the ankle and prevents the collar from riding down mid-workout. Hidden plait construction provides durable stretch support at the arch, while lightweight, 100% American merino wool fights odor-causing bacteria build-up. U.S. Merino Wool Merino wool is soft, itch-free, naturally odor- and bacteria-resistant, cool in the summer and warm in winter. We source our 100% U.S. grown merino wool exclusively from sheep raised by American farmers on American farms. Light Cushion Cushion that is light in weight along the base of the foot only. This all-season construction is highly versatile. LOW CUT Below the ankle, this sock just barely peeks out of your shoe. Seamless Toe Closure Advanced knitting techniques create a totally flat connection in the toe box, reducing bulk and eliminating blister-generating friction. Durability Assured Reinforced construction and low-stress seam placement reduce wear and tear, increasing the life of the sock. Ingredients 50% U.S. Merino Wool 46% U.S. Nylon 4% U.S. Spandex
