Sidi AERON MTB Cycling Shoes Black Size 48

The Sidi AERON Black MTB cycling shoes size 48 are purpose-built for riders with very large feet who refuse to compromise. Size 48 is not a scaled-up version of smaller shoes — it is a fully engineered XC racing size designed for stability, control and long-distance comfort.

The ripstop upper with rubber reinforcements protects the foot on technical terrain while maintaining a clean, professional race silhouette. Dual NUUN 001C aluminum dials allow precise adjustment across the entire foot length, which is critical in size 48. The Firmor X internal support system stabilizes the foot during long climbs, sustained cadence and repeated accelerations.

The UNUM Ergo anatomical tongue distributes pressure evenly to reduce fatigue during marathon XC rides. A full carbon X2FC outsole with stiffness index 11 ensures efficient power transfer without flex loss, while rubber inserts improve traction on steep and slippery sections. The tool-free adjustable heel cup allows the Sidi AERON Black 48 to be tuned precisely, turning a rare size into a true performance advantage.
