The Sidi Crossfire 3 motorcycle boots in olive green/fluo yellow bring the greatness of the Crossfire 3 to a stitched-sole construction.

Key Features
- Offroad stitched sole — the rubber sole is stitched directly to the upper for durability and grip
- MXGP- and SX-engineered microfibre with integrated impact protectors covering the entire boot
- Dual Flex System upper with Hyperextension Block prevents dangerous movement while allowing full freedom to move
- Micro-adjustable, replaceable buckle system with 4 adjustable straps and an adjustable calf system for a tailored fit
- Replaceable shin plate, metatarsus insets and anatomic heel cup for lasting protection

Unleash Your Full Potential
The Crossfire 3 is designed to unleash a pro rider's full potential, fully adaptable to your physique. Four adjustable straps, the adjustable calf system and the flex system that allows a wide range of movement make it easy to find your perfect fit — so the boot works with your body, not against it.
All Movement, in Safety
Sidi introduced the concept of hyperextension control to the motocross boot, and has since mastered the art of preventing dangerous ranges of movement while allowing complete freedom to ride at your best. The Dual Flex System and Hyperextension Block support the leg through every jump, rut and landing.
Offroad Stitched Sole
The Crossfire 3's rubber sole is stitched directly to the upper for a robust, serviceable construction built to grip and last. It is a proven, race-bred detail that keeps the boot planted on any terrain, ride after ride.
Fit and Sizing
The Sidi Crossfire 3 is offered in a regular fit across EU sizes 40–50. 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.
