The Darn Tough Style 1034 Men’s 1/4 Ultra-Lightweight Run Sock is a quarter-height merino wool running sock knit with no cushion. The ultra-lightweight build puts the sock below the bulk threshold inside a racing shoe — runners who use full-cushion socks on longer runs often drop to this style for race day or speed work. True Seamless toe construction removes the toe seam.
Quarter height keeps the sock visible above a running shoe collar without riding up the calf, and the Black colorway the universal pick — disappears under any boot or pant. The lightweight merino blend wicks sweat, dries fast, and resists odor on consecutive runs — the pick for serious runners who want merino feel without added thickness.
Darn Tough is a family-owned Vermont mill and knits every pair in Northfield. Lifetime guarantee covers running pairs just like the boot pairs.
