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. 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. Our Work socks are crafted with durability and comfort in mind. These socks are designed to withstand the demands of hard work while keeping your feet cozy throughout the day. They are knit with 120 Needles, ensuring a dense, sturdy sock that can endure the rigors of demanding work environments.
