>Anti-friction device (AFD):

The slippery surface or sliding mechanism under the boot toe that helps it to slide sideways out of the binding toepiece during release


What occurs when the side of a boot hits the snow in a highly edged turn, forcing the ski’s edge out of snow and disrupting the carved arc


An industry-standard scale for calibrating the amount of pressure required to cause a binding to release. Every binding has a DIN range. Children’s bindings go as low as .75; downhill racers typically crank it up past 20.


A binding’s ability to absorb routine shocks and vibrations without releasing.

>Flat spot:

The interruption of a flexed ski’s otherwise smooth arc at the point where the rigid boot sole is clamped to it. Disrupts smooth carving.


A platform, usually made of plastic, used to raise both the boot and binding up off the ski, offering increased leverage


A more sophisticated, performance-enhancing lifter—often incorporating metal—designed to strengthen the ski, dampen vibrations and enhance leverage and edge-grip


The height of the heel in relation to the toe. A raised heel improves turn initiation.


The distance from the base of the ski to the bottom of the boot
