SIDI Crossair HD Enduro Billy Bolt Boots

Developed and used by professional hard-enduro rider Billy Bolt, the Crossair HD boots are built specifically for hard enduro and super enduro disciplines. Thanks to an internal fiberglass-reinforced exoskeleton, these boots provide full support and safety while maintaining an incredibly light construction. The rubber soles are directly stitched to upper, but what makes them truly unique are their trial-boot derived design and composition. This allows these boots 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. The Crossair HD Enduro boots are the result of SIDI's relentless dedication to engineering gear 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.
