Step into peak performance with the SIDI Crossair HD Enduro Boot, the world’s first boot built specifically for hard enduro. Developed with pro rider Billy Bolt, it delivers lightweight control, pro-level protection, and a responsive feel designed for the toughest terrain.

Weighing just 1700 grams (size 43), the Crossair HD combines SIDI’s signature durability with a dramatically lighter construction. Its fiberglass-reinforced internal exoskeleton gives full support and impact protection while keeping the boot agile for technical riding.

A trial-inspired rubber sole, stitched directly to the upper, offers exceptional grip on footpegs and on the ground—essential for steep climbs, rock sections, and constant transitions. Every detail was refined through real-world feedback from Billy Bolt, resulting in a boot that reflects his demanding style and SIDI’s engineering expertise.
