Sidi Crossair HD Enduro Boot

Lightest Pro-Rider Boot

The Crossair HD is the lightest pro-rider boot in the world, built with hard enduro-specific input from Billy Bolt. Its ultra-lightweight fiberglass exoskeleton delivers the protection and support racing demands—without the weight holding you back.

Total Support, Zero Restriction

An internal fiberglass exoskeleton, hinge system, and anatomically shaped heel cup keep your foot locked, supported, and free to move naturally. Add in replaceable micro-adjustable buckles and you get a precise, dialed-in fit every ride.

Next-Level Protection

Stay covered with a durable shin plate, reinforced impact protectors on the front, side, and toe, plus the exclusive 3-point anti-hyperextension system. The Crossair HD keeps you safe from dangerous degrees of movement while giving you the freedom to push harder.

Maximum Control, Enduro Ready

The Crossair HD’s advanced rubber sole and thin inner panel bring you closer to your bike for maximum feel, grip, and stability. Whether on the track or extreme terrain, nothing else delivers the same connection and control.
