The Darn Tough Men’s Steely Boot Midweight Work Sock (Style 2017) in Graphite is a men’s work boot sock with a midweight cushion layer underfoot — denser than lightweight daily socks, thinner than heavyweight winter socks — for long days on concrete, jobsite floors, and work boot interiors. The boot-height shaft rises above a standard work boot, keeping the cuff clear of the boot collar. True Seamless toe construction closes the front of the sock smoothly so there’s no seam rubbing across full workdays.
The merino wool, nylon, and Lycra spandex knit handles moisture wicking and temperature regulation through hot summer shifts and cold winter starts — the temperature range that overheats cotton socks and soaks synthetic-only work socks. The mid-level cushion density adds underfoot comfort against hard floors without packing the boot. Graphite is the dark neutral workwear colorway.
