ABSTRACT:
A ski having a sole equipped with discontinuous serrations including a central flat gliding zone and on one side, at least, a lateral curved gliding zone bordering the central zone. The surface of the rear portion at least, of the central zone between the rear contact line and the center line of the boot of the ski is equipped with a pronounced structuring such that the measured values of the significant roughness parameters Rtm and Rku are greater than the values measured on the surface of the lateral curved gliding zone. The invention is more specifically related to an alpine ski whose ability to pivot and to glide are thus improved.
