The alpine boot shaft stiffness is an often discussed parameter. Nevertheless, academics and people from the industry still lack an indisputable method of measurement.

This research investigates some parameters that could influence the measuring of boot shaft stiffness.

The preliminary conclusion is that the boot/foot system, as a whole, should be considered the same way as the boot/binding system is considered for the release of the leg during a fall, and, therefore, the stiffness of the boot cannot be described without considering the foot.
