摘要

Sports boot, in particular for the practice of gliding sports, obtained from an external sole (11) adapted to be fixed at least by a front part (11a) on a gliding member (30) and comprising a rod (10) provided with a rear stiffener (12) on which is articulated a rigid collar (13, 13a, 13b) intended to surround the lower leg and which extends towards the top of the rod (10) on the basis of the articulation (14), -, beyond its upper end, the boot comprising, in addition, the energizing means (40) of the angular longitudinal control of the gliding (skate,...) in the air, with respect to the sole (11) of the boot during the phase of advancing of the gliding device (30), which are disposed between a fixed point (a) of the rod (10) and a mobile point (b) of the journalled collar (13, 13a, 13b) and which comprise at least one elastic member constituting a source of energy which can be charged during a phase of pushing on the ski (30) and to be released during the phase of advancing, characterized in that the resilient member (41, 61, 71, 81, 91, 101) constituting the source of energy is associated with means (50, 60, 70, 80, 90, 100), so as to be activated only between a substantially median position of equilibrium (0) of the boot and a position of the end of the thrust (o1).
