Abstract
Tread for the soles of long-distance ski boots (12), the tread consisting of grooves cooperating with mating ridges, the grooves and ridges being comprised in a sole (16) and in a plate (13) which is fitted to or forms part of a long-distance ski (10), the grooves (19-20) diverging from each other in the direction of the heel of the boot.
Claims8
A system for binding the soles of a long distance ski boot to a ski so that the lateral thrust during skating steps is efficiently transferred from the boot to the ski, said system comprising:
- a long distance ski boot including:
- a bridge formed laterally across the anterior portion of said ski boot, said bridge being releasably secured to said ski by attachment means;
- a sole, said sole having at least a first and a second divergent elongated groove formed therein, the vertex of said grooves being located adjacent said bridge;
- a plate coupled to the long distance ski, said plate having at least a first and a second divergent elongated ridge formed therein for mating with said grooves, thereby securing said ski boot with said plate;
- and
- wherein said grooves decrease in depth and said ridges decrease in height from their vertices to their posterior ends.

- a long distance ski boot including:
- a bridge formed laterally across the anterior portion of said ski boot, said bridge being releasably secured to said ski by attachment means;
- a sole, said sole having at least first and second posteriorly divergent elongated grooves formed therein and a frontal hollow portion interconnecting the anterior ends of said grooves, said frontal hollow portion being located adjacent said bridge;
- and
- a plate coupled to the long distance ski, said plate having at least first and second divergent elongated ridges formed therein, said ridges being interconnected by a frontal ridge portion for mating with said grooves and said frontal hollow portion, thereby securing said ski boot with said plate.
