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. Full Cushion: High-density cushion from top to toe for all day performance. Extended Crew: Extends firmly to the base of your calf to provide additional warmth and support. 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. Farm to Feet is committed to the single, simple goal of creating the world’s best wool socks by exclusively using an all-American recipe: US materials, US manufacturing, and US workers. With its supply chain completely within the U.S., Farm to Feet is able to ensure the highest quality materials and end products, while having as little impact on the environment as possible
