Product DetailsThe Courtney Crew is for those who want to push their limits on challenging terrain. Designed in collaboration with professional ultrarunner Courtney Dauwalter, these socks are built to meet the demands of the toughest trails! Our innovative toesock design minimizes friction between the toes to help eliminate blisters, frees them to splay naturally, and lets you utilize your whole foot on narrow, uneven trails. The Crew height provides mid-calf coverage to keep out debris, while COOLMAXA(R) EcoMade fibers and a breathable mesh top keep feet cool and dry, even during the longest races. Made with Midweight cushioning and nylon fibers, the Courtney Crew socks provide comfort, durability, and performance.
