The Sidi Crossfire 2 SM motorcycle boots in black are a high-performance supermotard boot built on the proven structure of the Crossfire. Designed specifically for supermoto, they unleash the rider's full potential with the safety, support and ride comfort of a race-bred boot — including anti-hyperextension protection, four-buckle closure and the SRS replaceable sole system.
Key Features
- Supermotard-specific sole with SRS technology — replaceable in the blink of an eye, in two versions (more or less stiff)
- Scratch-resistant microfibre upper for long-lasting defence against debris
- Anti-hyperextension system prevents over-extending movements to protect the ankle area
- Four-buckle closure with a micro-adjustable, replaceable buckle system and adjustable calf system for a tight, secure fit
- Imperceptible shield protects the entire boot leg from impacts
- Replaceable shin plate, metatarsus insets and anatomic heel cup for lasting protection
Supermotard Soul
Built on the structure of a Crossfire to unleash the rider's full potential, the Crossfire 2 SM delivers safety and ride comfort tuned for supermoto. The Dual Flex System upper and adjustable calf system adapt the boot to your physique, so you stay precise and in control from the start line to the flat track.
All Movement, in Safety
Moving is safe with the anti-hyperextension system, which avoids over-extending movements to protect the ankle. Among the many technological solutions built in, the imperceptible shield guards the whole boot leg from impacts — security that does its job without ever getting in your way.
100% Always with SRS Sole
The sole is replaceable in the blink of an eye with the SRS system, so you always have the best grip underfoot. Two sole versions are available — more or less stiff — to match your setup and riding style.
Fit and Sizing
The Sidi Crossfire 2 SM is offered in a regular fit across EU sizes 41–48. 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.
