Darn Tough remains preferred sock for those finding their tough at Spartan races

Northfield, VT. (July 30, 2019) – Darn Tough Vermont, the fastest growing American manufacturer of premium performance outdoor and lifestyle socks, is furthering its ongoing support of Spartan racers as the official sock of the Spartan Race US race series, which now includes Spartan Trail US. As athletes dig deep to push their mental and physical limits while training for and completing Spartan series races, Darn Tough socks offer unmatched comfort, durability and fit for the toughest obstacles and terrain, and unrivaled durability for long months of cross training, all backed by an unconditional lifetime guarantee.

“Spartan athletes are known for their relentless spirit, pursuit of greatness and pushing beyond the comfort zone; the same has been said about Darn Tough,” said Ric Cabot, president and CEO of Darn Tough Vermont. “Darn Tough and Spartan were both born in the mountains of Vermont and share a mindset of grit and persistence.  It’s a natural alignment for us to partner with Spartan for the second year and through 2020 with socks that help every athlete find their tough.”

Whether a first-time OCR racer or a seasoned pro, anyone undertaking the challenge of Spartan relies on the toughest gear to help them perform at their personal best. Darn Tough is bringing two new socks to the course for 2019 and 2020, the Beast and the Trifecta. Both socks are offered in quarter and over-the-calf heights, with moisture wicking, temperature regulating Merino wool and designed with knitted flex zones for comfort, breathability, and an uncompromising fit.

“We are excited to extend our national partnership a brand that shares the same ‘Made in VT’ authentic roots as Spartan and provides the highest quality socks for our OCR and trail running communities,” said Ian Lawson, Spartan VP Global Partnerships.

Two top competitors racing in Darn Tough’s custom Spartan sock include Nicole Mericle and Robert Killian, both Darn Tough sponsored Spartan athletes currently ranked 2 and 23 respectively on Spartan’s Elite World Series leaderboard.
