The Darn Tough Style 2017 Men’s Steely Boot Midweight Work Sock is a boot-height merino wool work sock knit with midweight cushion density through the foot. The cushion absorbs impact on hard job sites and long shifts, and the mid-calf boot height clears the top of a standard work boot. True Seamless toe construction removes the toe-box seam that causes hot spots under load.
The Graphite colorway a dark iron-gray that disappears under work boots. The merino wool blend wicks sweat, regulates temperature across hot and cold job sites, and resists odor through consecutive shifts — the reason guys who stand all day in work boots run merino instead of cotton. The fine-gauge knit holds shape across repeated washes.
Darn Tough is family-owned and knits every pair at their mill in Northfield, Vermont. Lifetime guarantee is unconditional — the sock gets replaced if it ever fails.
