  • Cross-country ski having alternate sliding and holding surfaces
    Patent number: 4027895
    Abstract: A ski for cross-country skiing, with a sliding surface intended to cooperate with a snow-covered ground, has a slot arranged through the ski in a longitudinal direction which divides the sliding surface into two parts. The first part is intended for a treatment in such a manner that a firm grip occurs against the ground and the second part is intended for a treatment in such a manner that a sliding occurs against the ground. The binding is arranged in such a way that the first part is pressed against the ground when a grip towards the ground is desired and the second part is pressed against the ground when a sliding towards the ground is desired.
