Abstract
A cross country ski in which, in the central portion of the ski, in the gripping zone of the boot, the heel zone acts as a support of the foot during a sliding phase, and a metatarso-phalangian support zone of the impulsion in the impulsion phase of the ski, a transverse slit is arranged, crossing the ski. The slit defines two flexion beams, upper and lower, respectively, in the thickness of the ski. This arrangement enables, during the impulsion phase, a good flattening on the ground of the lower beam and thus of the sole portion of the ski, i.e., the waxing chamber. The efficiency of the impulsion is thus substantially increased without affecting the sliding phase.
