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.
