Eighteen-centimeter cuffs put these socks squarely in the sweet spot that's dominated cycling for the past few years—tall enough to look intentional, short enough that you're not venturing into compression sock territory. The Castelli Originale 18 Sock nails the aesthetic that's become standard in the pro peloton while delivering the technical details that matter when you're three hours into a ride and your feet are the last thing you want to think about.

These are the socks you throw in your drawer and grab without thinking, which is exactly what a good cycling sock should be.
