Sidi GENIUS X Road Shoes - Black 2026

SIDI Genius X Road Shoes: The icon of comfort and performance reimagined

The SIDI Genius X is designed for demanding cyclists who refuse to choose between power transfer and absolute comfort. A true heir to 11 generations of perfection, it is aimed at both competitors and cyclosportive riders seeking stability and durability on long distances.

A custom-adapted fit for all your rides

The premium microfiber upper offers a supple touch that contours to the foot while maintaining a firm structure under pressure. Coupled with the Anatomical TPU High-Density Instep closure system, it effectively reduces pressure points on the instep while stabilizing the foot for maximum efficiency, even after hours in the saddle.

Technology and smooth power transfer

Equipped with the R3CC carbon composite sole, the Genius X features a stiffness index of 6. This technical choice allows for smooth energy transfer to the pedals while filtering road vibrations. The new aluminum NUUN 001C closure system adds an aerodynamic touch and exceptional micrometric precision for a perfect fit in one motion.
