Targeted Light Cushion: High-density cushion targeting critical performance areas throughout the sock. 3/4 Crew: 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. Durability Assured: Reinforced construction and low-stress seam placement reduce wear and tear, increasing the life of the sock. U.S. Merino Wool: Merino wool is soft, cool in the summer and warm in winter. Care Instructions: Wash Me Less - To maintain the durability of your Farm To Feet socks, machine wash in cold water and line dry or tumble dry with no heat.
