Castelli Aero Race Pro

he goal was to develop an aero sock without sacrificing the things that make a really good sock. We worked with Italian knitting experts and used state-of-the-art machinery to create a structure that combines smooth and textured areas to control airflow and reduce drag without compromising comfort or fit. The result is a sock that doesn't slip, feels great, offers aerodynamic performance and is in no way inferior to ribbed Lycra cuffs. They are also suitable for everyday wear. The comfort of a classic sock with structured aero ribs. Developed for better aerodynamics in everyday use. Durable and breathable design. 90 % polyamide / 10 % elastane mix for optimum comfort and fit. 20 cm high cuff.
