Castelli Aero Race Pro 20 Sock

Our goal was to develop an Aero sock without compromising on the qualities that make a really good sock. To achieve this, we collaborated with experts in Italian knitting and used state-of-the-art machines to create a structure that combines smooth and textured areas to control airflow and reduce drag, all while maintaining comfort and fit. The result is a sock that stays in place, feels great, offers aerodynamic performance, and rivals ribbed Lycra® cuffs. Additionally, it is also suitable for everyday wear.
