The Darn Tough Men's Stanley K Gravel Grey Mid-Calf Lightweight Wool Work Socks are a testament to rugged craftsmanship and thoughtful design. Developed through collaboration with Alaska's Salmon Sisters and their crews, these socks are engineered for those who demand both durability and comfort during long, laborious days. The mid-calf length, ideal for pairing with rubber boots, rises just above a 12-inch boot, providing ample coverage. Constructed with lightweight merino wool, these socks excel in moisture management, ensuring your feet remain dry and fresh throughout the day. The advanced design includes a cushioned footbed that delivers exceptional comfort, while the mesh windows promote breathability to keep your feet cool. An extended protective toe box offers added impact protection, and the performance fit eliminates sock slip and bunching, essential for maintaining focus and productivity. Proudly made in the USA at our Vermont mills, these socks come with an unconditional lifetime guarantee. If they fail to outlast any other socks you've owned, a replacement is assured. With terry loop cushioning to safeguard the footbed and ankle, these socks are an indispensable asset for hardworking feet.
