Sidi AERON MTB Cycling Shoes Black Size 40

The Sidi AERON MTB cycling shoes size 40 are built for riders who demand precision and control in XC racing and marathon MTB riding. The ripstop upper with rubber reinforcements protects the foot while maintaining a lightweight, stealth race profile. Dual NUUN 001C aluminum dials allow fast, accurate adjustment on the move.

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