Used by Pro riders in Motocross, Supercross, Hard Enduro and Super Enduro, the Crossair delivers all the solidity of premium Sidi in just 1665 grams (43 size). So much lighter than anything else.An internal fiberglass reinforced exoskeleton delivers all the support and safety while maintaining an incredible light construction. Its sole has been developed together with Vibram® to reach a new level of grip and flexibility. Nothing compares to the riding experience of Crossair. The CROSSAIR anti-hyperextention structures are designed to support movement but prevent dangerous degrees, so the riders are always in control and free to move.The boot has three anti hyperextension systems for the foot, all removable: the first is located on the first hinge , the second on the back of the boot (the bootleg leans on the ankle avoiding an extra bending backwards), the third is frontal and it is made up of an innovative system that, through a screw on a replaceable insert, allows a specific tibia flexion range and freezes if bending is excessive. A bootleg in PU, connected to the ankle strap through the second hinge, protects the back of the boot and is positioned between the upper and the lining.The CROSSAIR toe section is entirely wrapped in a plastic protection enhanced with a geometric design for greater grip. The boot is equipped with protection on the metatarsus: a rigid and replaceable nylon insert protects the inside of the boot in case the rider’s foot slips off the footpeg. The PU heel is shaped and specially moulded to improve foot safety in case of torsional twists and is shaped to ensure comfort and stability. For the lower buckle a spoiler has been added to deflect debris away from the buckle. The ankle panel with the central strap can be replaced by 4 screws that connect it to the boot.
