DescriptionThe whole story

The Sidi Crossair motorcycle boots in black set the bar higher. Used by pro riders across MX, hard enduro and super enduro, the Crossair delivers all the solidity of a premium Sidi boot at just 1,665 grams (size 43) — far lighter than anything else. An internal fibreglass-reinforced exoskeleton provides full support and safety in an incredibly light construction, while the Materiis sole compound, developed with professional riders, reaches a new level of grip and durability.

Key Features

  • Internal fibreglass exoskeleton delivers pro-level support and safety at just 1,665 g (size 43)
  • MXGP- and SX-engineered microfibre with protectors on the front, side and toe, plus a thermoplastic defender toe area
  • Anti-hyperextension system supports the whole leg while protecting against excessive movement
  • Velcro closure with a micro-adjustable, replaceable buckle system for a solid, individually fitted hold
  • Hinge system, anatomic heel cup and replaceable metatarsus insets for protection and freedom of movement
  • Materiis exclusive compound sole — MXGP- and SX-proven grip and durability

The Lightest Pro Boot Ever

How do you make the lightest pro boot ever? You build it around an internal fibreglass exoskeleton that offers the safety and support extreme riding demands in a lightweight structure. Nothing else delivers the same riding experience: all the support and protection racing requires, without the burden of weight.

Protected from Dangerous Movements

The incorporated anti-hyperextension structure supports the entire leg of the boot while preventing dangerous ranges of movement — so you stay in control and free to move. Combined with the hinge system and anatomic heel cup, it protects without ever feeling restrictive across MX, hard enduro and super enduro.

Materiis Exclusive Compound

Developed together with professional riders, the Materiis sole compound reaches a new level of grip and durability. MXGP- and SX-proven, it delivers the traction and longevity that competition demands, ride after ride.

Fit and Sizing

The Sidi Crossair is offered in a regular fit across EU sizes 37–50. 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.
