U.S. Merino Wool: We source our 100% U.S. grown merino wool exclusively from sheep raised by American farmers on American farms. Merino wool keeps you cool in the summer and warm in winter. Targeted Light Cushion: High-density cushion targeting critical performance areas throughout the sock. 3/4 Crew Height: A slightly shortened crew that fits just below the calf but above a hiking boot. Seamless Toe Closure: Advanced knitting techniques create a totally flat connection in the toe box, reducing bulk and eliminating blister-generating friction. Care Instructions: To ensure long-lasting comfort and fit, Farm To Feet socks should be machine washed cold and laid flat to dry. At the crossroads of some of the most scenic trails in America, the little Virginia town of Damascus inspired our most technology-packed hiking sock. Durable enough to take on major miles, this lightweight three-quarter crew is the favorite of hikers and backpackers who prefer a lower height sock. Sourced entirely from US ranchers, the Damascus features a 19.5-micron merino wool knit, as well as multiple ventilation channels and targeted full-density cushioning in traditional problem areas.
