A sport boot, particularly for performing a gliding sport, produced from an outer sole capable of being fastened at least to one forward part on a gliding member, and including a lower shank connected to a rear heel cap on which a rigid collar is hinged which is designed to surround the lower leg and which extends towards the top of the shank starting from the hinge beyond the upper end thereof, the boot also including an energized arrangement for the angular longitudinal control of the gliding element in the air in respect to the sole of the boot during the phase of advancement of the gliding element, which are disposed between a fixed point of the shank and a movable point of the hinged collar, and which include at least one resilient member constituting an energy source capable of being tensed in the course of a pushing phase on the ski and to relax in the course of the advancement phase, wherein the resilient member which constitutes the energy source is connected with a disengaging arrangement such that it is activated only between a position of the boot of equilibrium which is essentially median, and a position at the end of pushing.

A sport boot for attachment to a gliding member for performing a gliding sport, said boot comprising: an outer sole having a forward part, at least said forward part being adapted to be connected to the gliding member; a lower shank fixed with respect to said outer sole, said lower shank having a heel cap; a rigid collar extending upwardly from said lower shank and being adapted to extend around a lower leg of a user of the boot; a hinge connection between said lower shank and said rigid collar for enabling movement of said collar, with respect to said lower shank and with respect to the gliding member, between a maximum forward position and a maximum rearward position and through an intermediate equilibrium position; and an elastic device for biasing said collar in a direction toward said maximum forward position, said elastic device extending between a first part fixed with respect to said lower shank and a second part fixed with respect with said collar for movement of said second part with respect to said first part, wherein said elastic device and one of said first part and said second part comprise a disengagement device, said disengagement device enabling said elastic device to be operative for elastically biasing said collar only between said maximum rearward position and said intermediate equilibrium position, said disengagement device enabling said elastic device to be inoperative for biasing said collar forwardly between said intermediate equilibrium position and said maximum forward position, wherein the boot comprises no means for elastically biasing said collar in a rearward direction from said maximum forward position toward said intermediate equilibrium position.
