While the boots offer advanced protection and features, their design is specialized for hard enduro and super enduro. Beginners may find them more complex than entry-level boots, but they provide excellent safety.

Clean Technomicro with a damp cloth and mild soap if necessary. Avoid abrasive cleaners or solvents that could damage the synthetic leather.

Yes, the micro-adjustable and replaceable buckle system means individual buckles can be replaced if they become damaged.

The HYPER EXTENSION SYSTEM is designed to prevent the ankle from bending backward beyond its natural limits, reducing the risk of injury during impacts or awkward situations.

The double FLEX SYSTEM allows for more natural ankle flexion in two points, improving mobility for better control and comfort during riding, especially on uneven terrain.

The CROSSAIR HD boots are designed to be compatible with most standard knee braces. The calf section is shaped to accommodate them, but it's always recommended to try them on with your specific braces if possible.

The CROSSAIR HD line is specifically developed for the demands of hard enduro and super enduro, featuring unique hinge systems and enhanced protection tailored for these disciplines, distinguishing them from Sidi's road or general motocross boots.

Ensure there is no dirt or debris obstructing the buckle mechanism. Clean the buckles gently. If the issue persists, the buckle may need replacement.

This is common with new, high-performance boots. Wear them around the house for several hours to break them in. The materials will become more supple with use.

Re-check the adjustment of all buckles, especially the ones around the ankle and calf. Ensure the retention tape closure is secure. The HYPER EXTENSION SYSTEM is designed to prevent over-extension, not to lock the ankle.

The boots are designed with protection in mind, which can sometimes lead to reduced ventilation. Ensure you are wearing moisture-wicking socks. Continued use will help assess if this is a break-in issue or a characteristic of the design.
