In designing our Women’s Athlete Edition Run Print Crew Socks, we partnered with ultrarunner Rob Krar to determine which comfort and performance features were best suited to this runner-focused sock. It starts with Merino wool construction, which provides odor resistance and temperature regulation, and adds in a performance-oriented and women's specific fit, a Virtually Seamless™ toe, and breathable mesh zones. Next, this sock offers Indestructawool™ and Shred Shield™ technologies for enhanced durability. To top it off, the sock is patterned with an eye-catching print that’s sure to get noticed next time you podium.
