Darn Tough is proud to sponsor “Sherpa John Lacroix. For his age, (or any age as far as I’m concerned) Sherpa John is no doubt one of the toughest and most accomplished runners out there. He just got back from his first race for the season, the McNaughton Park 150 Mile Endurance Run in Pekin, IL (2nd Longest Race in the Western Hemisphere). Temperatures were in the mid 30’s, winds were blowing at 30+mph, combined with rain and snow showers, this was one miserable race. “One thing WAS for sure,” said Sherpa ” my Darn Tough socks kept my feet cool, comfy and warm when needed. Your socks are like gold to my feet and I thank you guys so very much for your support.” John prefers test the limits of human endurance in our 1/4 Coolmax cushion.
