Abstract: A boot for gliding sports, and more specifically, for "snowboarding". The boot includes two distinct zones with different characteristics and functions, including a first relatively rigid energy/power circuit, distributed with respect to the foot, so as to centralize the forces, and especially the front and rear supports or the torsion control, during practice of the sport, and a second relatively flexible, sensitive circuit independent of the energy/power circuit, and adapted to ensure comfort of the foot as well as transmission of information originating from the gliding member towards the ankle. Both of the circuits are affixed to a common reference element.
