CROSSAIR HD – DESIGNED FOR EXTREME ENDURO PERFORMANCE

The Crossair HD by SIDI is the world’s first boot specifically designed for hard enduro and super enduro. Developed and worn by professional rider Billy Bolt, this boot sets a new benchmark in performance, protection, and weight.

With all the premium features expected from SIDI, the Crossair HD weighs just 1700 grams (size 43), making it significantly lighter than any comparable product. The internal glass fiber-reinforced exoskeleton offers maximum support and safety while maintaining a lightweight and agile structure.

The rubber sole is stitched directly to the upper, inspired by trial boots, delivering unmatched grip on both footpegs and rough terrain. Every detail is the result of continuous development to meet the specific demands of Billy Bolt and the highest standards of modern enduro racing.
