ABSTRACT:
A ski comprises a longitudinally extending body having a central region interposed between anterior and posterior segments. The body has a lower sliding surface whose width is defined by a pair of opposed lower edges connected to two lateral side surfaces that are inclined relative to the lower sliding surface. An upper surface is connected to the laterally side surfaces and has a width defined by opposed lateral edges which diverge towards the front of the ski in the interior segment of the body, and which are substantially parallel to each other in the posterior segment.
