The Castelli Aero Race Pro 20 Sock is their version of an aero sock that doesn't compromise on the things that make a great sock. Working with expert Italian knitters and state-of-the-art machinery they created a structure that combines smooth and textured zones to control airflow and reduce drag mdash without sacrificing comfort or fit. The result is a sock that stays up feels great and delivers aero performance equal to ribbed Lycra cuffs mdash with the bonus of true everyday wearability. | Castelli Aero Race Pro 20 Sock Belgian Blue - SM
