Ski-runs in the High Alps

by F. F. Roget

Here none but the pressure exerted by means of the heel-band fastener upon the fulcrum (toe-straps and cheeks) controls the ski.

If the reader will kindly remember what we said about the axis of rotation lying across the ball of the foot, he will now understand that the heel-band has to describe “some portion of a circle” on the apex A, as follows:—

CORRECT LEVERAGE.

each time the foot moves up and down in the vertical line.

Consequently the principles of a schematic binding work out in this way:—

First: That the heel-band be free to move in a horizontal plane, and be made to run through the fastening lever instead of being itself attached to the ski by an extremity.

Second: That the heel-band run loosely through a loop or sleeve placed on the apex of the foot axis on each side of the ball of the foot. The band will hinge on the loop, else it would slacken and tighten as the foot rises and falls.
