摘要

(57) [summary] and bottom with [challenges and solutions] narrow groove, and a flat gliding for the central zone, at least on one side, ski including a curved slide for the side area bordering the central zone I provide. Rear contact line 11 and the surface of at least the rear portion of the central area 5 located between the center line of the ski shoes, gliding for side measurements of significant parameters of curved roughness Rtm and Rku zone 6, 7 pronounced structuring such as greater than the value measured on the surface of the site that is, and a narrow groove 50, 70. In particular, the present invention relates to the Alpine ski with improved turning performance and glide performance.
