Sidi AERON MTB Cycling Shoes Ice White Size 45.5

The Sidi AERON MTB cycling shoes size 45.5 are designed for riders who need precise half-size fit and stability during long XC races and marathon MTB rides. The ripstop upper with rubber reinforcements protects the foot while keeping a lightweight, race-focused profile. Dual NUUN 001C aluminum dials allow fast and accurate adjustment on the move.

Firmor X internal support and a tool-free adjustable heel cup stabilize the foot during long climbs and sustained high-cadence efforts. The UNUM Ergo anatomical tongue reduces pressure points over extended distances. A full carbon X2FC outsole with stiffness index 11 ensures efficient power transfer, while rubber inserts improve traction on technical sections.
