The boot that raises the bar. Developed and used by Billy Bolt, professional hard-enduro rider.

The Crossair HD is the first boot in the world designed and built specifically for the disciplines of hard enduro and super enduro. It offers all the qualities of Sidi's premium products, with a weight of only 1700 grams (size 43), resulting in being much lighter than any other alternative. The internal exoskeleton reinforced with fiberglass offers all the support and safety needed, while maintaining an incredibly lightweight structure. The rubber sole is sewn directly onto the upper, and what makes it unique is the design and composition derived from trials boots. This allows the boot to be lightweight, protective and to offer unparalleled grip both on the peg and on any terrain during hard enduro activities. The Crossair HD is the result of tireless dedication to engineering a product that, through continuous evolution, has satisfied all of Billy's requests and responded to his every need. It incorporates the perfect fusion between Billy Bolt's unparalleled style and Sidi's manufacturing experience.
