Sidi AERON MTB Cycling Shoes Black Size 47

The Sidi AERON Black MTB cycling shoes size 47 are designed for riders with very large feet who demand stability, confidence and long-distance comfort in XC racing and marathon MTB riding. Size 47 provides even support across the entire foot, ensuring predictable performance during sustained efforts.

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 full foot length. The Firmor X internal support system stabilizes the foot during long climbs, steady cadence riding and repeated accelerations.

The UNUM Ergo anatomical tongue distributes pressure evenly for lasting 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 47 to be precisely tuned for confident, endurance-ready performance.
