The Darn Tough Style 1054 Run Coolmax No Show Tab is an ultra-lightweight running sock built around Coolmax polyester instead of merino wool. A thin layer of cushion runs along the bottom of the foot to absorb impact, True Seamless toe construction fuses the toe seam, and the low tab at the heel keeps the sock in place without rubbing the Achilles.
This is the sock for hot-weather running, summer training, and races in humidity. The 48% nylon / 47% Coolmax / 5% Lycra blend is engineered specifically to move moisture away from the skin and dry fast — faster than the merino wool counterpart — while still holding the sock’s shape through long runs. No show tab height means it disappears inside low-profile running shoes.
Darn Tough still knits every pair at their family-owned mill in Northfield, Vermont. The unconditional lifetime guarantee applies to this sock too: wear it out and they’ll replace it.
