Castelli Aero Race Pro 20 Socks - white 001

Castelli’s goal was to develop an aero sock without sacrificing the qualities that make a truly great sock. To achieve this, we collaborated with experts in Italian knitting 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 stays in place, feels great, delivers aerodynamic performance, and rivals ribbed Lycra® cuffs in every way. Plus, it’s suitable for everyday wear. Features of the Castelli Aero Race Pro 20 Socks: Traditional sock comfort with raised aero ribs Designed to improve aerodynamics in everyday riding Durable and breathable construction Nylon/spandex blend for optimal comfort and fit 20 cm cuff Material 90% polyamide, 10% elastane
