Ski adapted to receive the boot of the skier, the ski has a front tip, a rear end, and a central zone located between the front tip and the rear end and which, when positioned on a flat surface, includes at least two contact lines with the flat surface, such contact lines being a forward contact line, positioned in the vicinity of the front tip, and the rear contact line, positioned in the vicinity of the rear end; the distance separating the forward contact line and the ski tip is greater than 500 mm or about 500 mm. The portion located between the front tip and the forward contact line, i.e., the shovel, has a convex zone, which includes the following: a first shovel portion having a lateral shape comprised between an arc of circle with a 9-meter radius and an arc of circle with a 5-meter radius; a second shovel portion contiguous to the first shovel portion, whose shape is comprised between an arc of circle with a 9-meter radius and an arc of circle with a 1-meter radius; a third shovel portion contiguous to the second shovel portion and extending to the front tip of the ski. In a particular embodiment, the shape of the first shovel portion and of the shape of the second shovel portion have no flat portions, which means that whatever a pair of points situated on a 150-mm chord distance from one another on the curve representing the lateral shape of the shovel, there is at least one point of the curve between the pair of points, which is more than 0.5 mm away from the chord joining the pair of points.
