The Sidi Crossair X motorcycle boots in black deliver all the support, control and protection you need — without the extra burden. Engineered for MXGP and SX, the Crossair X wraps the entire boot in high-density impact protectors within a light, flexible structure built to perform, and rides on a Materiis compound sole developed for the control and durability a Supercross championship demands.
Key Features
- Ultra-tough, high-density impact protectors cover the entire boot for maximum safety
- MXGP- and SX-engineered microfibre stands up to the toughest conditions with durability and flexibility
- Internal fibreglass exoskeleton provides support during jump landings
- 3-point anti-hyperextension system protects against dangerous movements while allowing constant motion
- Durable, tough premium nylon buckles for a secure, adjustable fit that withstands motocross
- Materiis compound sole with Capta pattern — Supercross- and MXGP-proven grip and extreme durability
Robust Shield
The Crossair X is fortified with ultra-tough protectors that cover the boot, guarding against impacts and abrasions for maximum safety on the track. Replaceable protection parts and a calf section keep it race-ready season after season.
Move Constantly in Safety
A 3-point flexion-control structure allows constant movement while maintaining safety and stability, supporting natural motion without compromising protection. Combined with the internal fibreglass exoskeleton, it delivers support exactly where the forces of jump landings demand it.
Seamless Inner and Unrivalled Grip
An ultra-sleek inner design ensures a snug fit with no gaps, for superior comfort and control that leaves you seamlessly connected to the bike. Underfoot, the Materiis compound — proven in Supercross and MXGP — offers unmatched grip and extreme durability for reliable traction in the most challenging environments.
Fit and Sizing
The Sidi Crossair X is offered in a regular fit across EU sizes 39–50. If you ride in thicker socks or sit between sizes, we recommend sizing up. Consult the Sidi size chart before ordering to confirm the best fit.
