Abstract
Front- and/or central-entry ski boot equipped with a comfort sock (3) and having an upper/collar (4) made adjustable over the lower leg by transverse flaps (1) and closure systems (13). The upper (4, 44) is jointed around an axis (5) on the shell base (6) in the area of the malleoli and can pivot only in the forward direction, since a permanent stop-motion arrangement (14) on the shell base (6) prevents it from pivoting rearwardly. The shell base (6) incorporates, in the dorsal area of the heel (16), a vertical groove (17) open at the top and designed to allow passage of the rear-most point (20) of the heel (22) of the skier's foot when the boot is put on and removed, by deformation of the comfort sock (3) at that site, and a retractable flap (18), jointed by its lower part (19) to the shell base (6) in the area of the heel, closes this groove (17) in the skiing position of the boot by virtue of the action exerted on an actuating device (35) which also tightens it against the rear part of the skier's leg via the interposed comfort sock (3).
