We partnered with ultrarunner Rob Krar to design a sock purpose-built for long runs. With the 4 Degree™ elite fit system helping to ensure a performance-oriented fit, our Athlete Edition Run Print Crew Socks are created for comfort on even rugged trails. With breathable mesh zones, a Virtually Seamless™ toe, and Merino wool construction for natural odour and temperature control, this sock will help you rack up the miles. Plus, it’s got a pattern with a visual pop that just won’t stop—much like your endurance.
