This guy right here, the 6in Trail Sock, represents the center-of-the-road cuff height for Fox Racing's sock line. As for wicking, breathability, and ventilation, though, the 6in's blend of a synthetic body, mesh inserts, and Meryl's anti-stink Skinlife treatment means he's somewhere above average. Finishing touches like a supportive arch zone further distinguish him as a mountain bike foot sleeve, widening the gulf between our Mr. Medium and the navy argyle salary-man socks you wear to the skate park.
