Anti Hyperextension System 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.
