Introducing the Sidi Crossair HD Billy Bolt Edition – the world’s first motorcycle boot engineered specifically for hard enduro and super enduro disciplines. Designed in collaboration with world champion Billy Bolt, these boots combine elite performance, cutting-edge protection, and signature Sidi craftsmanship.

Weighing just 1700g (size 43), the Crossair HD sets a new standard in professional off-road footwear. Its fiberglass-reinforced internal exoskeleton offers full leg support and superior protection while remaining incredibly lightweight. With a trial-inspired rubber sole directly stitched to the upper, you get unmatched grip and feel—on the pegs and off the bike.

The anti-hyperextension system, long-lasting buckles, and replaceable protection parts deliver serious durability and safety for aggressive riders. The ultra-sleek inner panel offers greater bike contact and control, essential for navigating the extreme terrain of hard enduro riding.

This isn’t just a boot—it’s a revolution in rider gear. Born from Billy Bolt’s relentless pursuit of perfection and brought to life by Sidi’s iconic design legacy.

Key Features:

  • Hard Enduro Engineered Microfibre – Built for extreme riding conditions

  • Front, Side & Toe Protectors – Maximum impact resistance

  • Internal Nylon Fiberglass Exoskeleton – Superior support without added weight

  • 3-Point Anti-Hyperextension System – Prevents dangerous ankle movements
