As an all-season outdoor athlete, I burn through socks like an F1 racer burns through soft-compound tires. So I picked up a pair of Italian-made Zamberlan Path Socks to tide me over this summer. Whether I'm revving my engine running or biking, these thin, moisture-wicking merino wool socks have me gripping the ground like a tuned-up Ferarri on the racetrack. The socks are uniquely shaped for the left and right foot, so the fit is as precise as can be. $28; zamberlanusa.com.
