ABSTRACT:
The running surface of an Alpine ski has a front portion adjoining its tip, a rear portion, and an intervening middle portion supporting a binding, the three portions differing from one another in their profiling designed to exert a minimum guiding effect in the middle portion and a maximum guiding effect in the rear portion. The latter, therefore, has one or more longitudinal grooves whose combined cross-sectional area exceeds that of the groove or grooves of the front portion whereas the middle portion is grooved only slightly or not at all.
