CROSSAIR - Boots - UK 12

The boots utilize an internal fiberglass-reinforced exoskeleton and Technomicro microfiber construction, which provides robust support and protection without the bulk of traditional materials.

The Sidi Crossair boots are specifically designed for off-road racing and riding disciplines. While they offer excellent protection, their design and features are optimized for Motocross, Enduro, and similar activities, not for street use.

Refer to the Sidi sizing chart and measure your foot length accurately. The UK size 12 listed is equivalent to a specific foot measurement; compare this to your own measurements for the best fit.

The HYPER EXTENSION SYSTEM is a safety feature designed to prevent injuries by limiting overextension of the ankle, particularly when the leg bends forward beyond its natural range.

Yes, the Sidi Crossair boots feature a micro-adjustable and replaceable buckle system, allowing for easy replacement of individual buckle components if they become damaged.

With proper care and maintenance, the high-quality construction of the Sidi Crossair boots ensures a long lifespan, even under demanding riding conditions. Replaceable parts like the insets and buckles further extend their usability.

Ensure buckles are clean and free from mud or debris. Gently work the adjustment mechanism back and forth.

This is normal. Continue to wear the boots for short periods to break them in. The materials will soften and conform to your foot over time.

Ensure the FLEX SYSTEM is not obstructed. Check that the boot is properly sized; a boot that is too small can restrict movement.

The Vibram sole is designed for durability, but heavy use in abrasive conditions can cause wear. Consider replacing the sole if significantly worn, though this is typically a professional service.
