ABSTRACT:
The present invention relates to a linkage apparatus between a ski boot and a cross-country ski which comprises a linkage blade which is pivotally mounted to a ski and which is attached to the toe end of the ski boot. In one embodiment, a sliding finger is biased by a compressing spring and constantly exerts a resilient pressure against an inclined forward surface of the linkage blade to maintain the blade in an equilibrium position, when at rest or inoperative, which is at an angle of about 20.degree. with respect to the horizontal ski surface. In another embodiment, a compressible wedge is used to exert such a force on the blade, and the pivotable blade is attached directly to the forward surface of a ski boot.
