Sidi Crossair HD Boots

A boot that sets the bar higher. Developed and used by professional hard-enduro rider Billy Bolt. 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.
