DESCRIPTION
DESCRIPTION
The Crossair HD is the world's first boot designed and built specifically for hard enduro and super enduro disciplines. It delivers all the solidity of a premium Sidi boot, weighing just 1700 grams (size 43), making it much lighter than anything else.
An internal fiberglass-reinforced exoskeleton provides full support and safety while maintaining an incredibly light construction. The rubber sole is directly stitched to the upper, and what makes it truly special is its design and composition derived from trial boots. This allows the boot to be lightweight, protective, and provide unparalleled grip both when riding on the footpegs and in contact with any terrain encountered during hard enduro activities.
Crossair HD is the result of a relentless dedication to engineering a product that, through continuous evolution, met all of Billy's requests and fulfilled every need. It embodies the perfect fusion of Billy Bolt's unmatched style and Sidi manufacturing expertise.

// COMPLETELY ARMOURED
How did we make the lightest pro boot ever? We build it around an internal fiberglass exoskeleton that offers the safety and support that extreme riding requires in a lightweight structure. Thanks to the incorporated anti-hypertension system, the system supports the entire leg of the boot while protecting against excessive movement.
-
// THE LIGHTEST PRO BOOTS
Crossair HD is the lightest pro-rider boot in the world, and nothing delivers the same riding experience. Thanks to its fiberglass construction, you can have all the support and protection that racing requires, without the burden of the weight.
-
// PROTECTED FROM DANGEROUS MOVEMENTS
Our anti-hyperextension structures are designed to support movement but prevent dangerous degrees, so the riders are always in control and free to move. The trial specific sole ensures right grip and stability.
-
// GREATER BIKE CONTACT
Greater control of the bike is ensured by the inner thin panel to better get closer to the bike and have more feeling. Our anti-hyperextension structures
