Sidi Crossair Boot

The Sidi Crossair Boot sets a new benchmark as the lightest professional boot ever crafted, delivering elite-level performance without compromising safety. Trusted by professional riders across Motocross, Hard Enduro, and Superenduro, it combines premium Sidi materials with advanced construction to achieve an incredibly low weight of just 1665 grams (size 43)—noticeably lighter than competing boots. An internal fiberglass-reinforced exoskeleton provides exceptional support and impact protection while maintaining outstanding flexibility and freedom of movement. The result is a boot that enhances rider control, reduces fatigue, and delivers confidence in the most demanding riding conditions.
