Alpine ski with improved sidecut

Alpine ski comprising a tip zone located at the front of the ski, a waist zone, and a tail zone located at the rear of the ski, a median longitudinal plane extending from the front end to the rear end of the ski, an underside formed by a gliding sole bordered by edges, a zone for mounting a boot, the middle of which, in the longitudinal direction, is located at a mid-shoe line (MC), and having a sidecut with:

• a front contact line (PA) defined as the line of contact between the gliding sole and a horizontal surface against which the sole is pressed when the waist is loaded, which is located furthest forward, the front contact line (PA) forming the rear border of the tip zone, a rear contact line (PB) defined as the line of contact between the gliding sole and said horizontal surface, which is located furthest back, the rear contact line (PB) forming the front border of the tail zone,
• a line of greater front width (PI) located at or further forward than the front contact line (PA),
• a line of greater rear width (PII), located at or more rear than the rear contact line (PB),
• a zone of minimum width (PIII) located in the waist zone, said sidecut having a variable radius of curvature between the front contact line (PA) and the rear contact line (PB),
• wherein the width of the ski, measured perpendicular to the median longitudinal plane, at the front contact line (PA) is strictly less than the width of the ski measured at the rear contact line (PB) and in that the zone of minimum width (PMI) is further forward than the mid-shoe line (MC).
