The Darn Tough Men’s Ultra Light No Show Athletic Sock (Style 1437) in Charcoal is a men’s no-show sock built to stay hidden under a low-cut shoe — the cuff sits below the shoe collar so the sock is invisible in sneakers, casual trainers, and boat shoes. True Seamless toe construction closes the front of the sock smoothly, keeping the seam bump off the front of the foot during long walks and active days.
The knit — 52% Merino Wool, 44% Nylon, 4% Lycra Spandex — uses a merino-leaning blend where the merino pulls moisture off the skin and regulates temperature, and the nylon adds durability against repeated shoe-friction wear. The ultra-light construction keeps the foot low-profile inside tight-fitting shoes, and the 4% spandex holds the cuff in place so the sock doesn’t disappear into the shoe. Charcoal is the neutral men’s colorway that pairs with every casual and athletic kit.
Darn Tough knits every pair in Northfield, Vermont and replaces any pair that wears, tears, or develops holes under its lifetime guarantee.
