Castelli set out to develop an aero sock that didn't compromise on the qualities that make a great sock. Working with experienced Italian knitters and using state-of-the-art machinery, they created a structure that combines smooth and textured areas to control airflow and reduce drag—without sacrificing comfort or fit. The result is Castelli's Aero Race Pro 20 sock, which stays in place, feels great, and offers aero performance equivalent to ribbed Lycra® cuffs—with the added benefit of being truly wearable every day.
