Product details

The RR Fast 2 Aerolight by Sidi is a highly developed cycling shoe designed for demanding cyclists. With its proven durability and excellent grip, it offers both comfort and performance. The innovative sole combines nylon and carbon fibers to ensure an optimal balance of stiffness and flexibility, reflected in a stiffness index of 5. The shoe perfectly adapts to the shape of the foot thanks to its soft upper material, providing an outstanding wearing experience. The adaptive closure allows for quick and precise adjustments, while the hidden heel stabilization keeps the foot secure throughout the ride. Sidi focuses on longevity by using only the best materials and ensuring that all parts are replaceable, allowing the shoe to be used for years.
