We can't make this stuff up

  • Endurance running is a challenge that puts you through so much adversity that it reveals the truest parts of yourself. It is in embracing my whole self, acknowledging the bad, and embodying the good that I am able to find the strength to finish multiple day races. Darn Tough helps me every step of the way. Literally.

Performance Fit

From form fitting toe boxes to sculpted heel pockets and integrated arch support, our knitting techniques produce the finest fitting performance sock available.

Merino Wool

Our fine gauge Merino Wool naturally regulates temperature and wicks moisture. Never itchy, always on. Warm in the winter. Cool in the summer.

True Seamless

Using the latest generation of Italian knitting machines, we’re able to knit ultra-light yet extremely durable socks with an undetectable toe seam.
