Sidi Aeron 2026 MTB shoes

The Sidi Aeron 2026 rpushes the boundaries of cross-country MTB performance, combining lightness, stiffness and an ultra-precise fit. Designed for XC, Gravel and CX riders, they feature a rubber-reinforced ripstop fabric upper, ensuring excellent abrasion resistance without compromising on weight.

Support is provided by a dual NUUN 001C fastening system, combined with Firmor X internal reinforcement, for a secure and responsive lock-in even during full-on sprints. The UNUM tongue and quick-adjust arch support offer a consistent fit, free from pressure points.

Thanks to its tool-free heel adjustment, the Sidi Aeron adapts perfectly to the shape of the foot for optimal stability. Its stiff outsole (11/12) with wide rubber coverage ensures maximum power transfer and effective traction on all technical terrain. A shoe designed for modern XC racing, Gravel and Cyclo-cross.
