摘要： A length-adjustable short ski for mounting on a boot. The ski has a sole-receiving portion and a heel-receiving portion. Each of these portions has a platform, the heel platform overlapping the sole platform, and the platforms are interconnected by tongue-and-groove joints allowing their relative sliding displacement and holding the portions in assembled condition, the grooves and tongues projecting downwardly from the platforms. Once the sole and heel portions have been set to the desired length of the ski, they are locked together. For this purpose, the sole end of the heel platform has a resilient tongue with a pair of ribs projecting downwardly and locking into two of a plurality of locking notches formed in the underlying sole platform.
