Sidi AERON MTB Cycling Shoes Black Size 45

The Sidi AERON Black MTB cycling shoes size 45 are designed for riders with larger feet who demand stability, control and confidence during XC racing and marathon MTB riding. Size 45 provides even foot support and predictable fit during sustained power efforts and long climbs.

The ripstop upper with rubber reinforcements protects the foot on technical terrain while maintaining a lightweight, race-focused silhouette. Dual NUUN 001C aluminum dials allow precise adjustment across the entire foot length. The Firmor X internal support system stabilizes the foot during accelerations, climbs and high-cadence riding.

The UNUM Ergo anatomical tongue distributes pressure evenly for long-distance comfort. A full carbon X2FC outsole with stiffness index 11 ensures efficient power transfer, while rubber inserts improve traction on steep and slippery sections. The tool-free adjustable heel cup allows the Sidi AERON Black 45 to be precisely tuned for confident, race-ready performance.
