Abstract: Ski boot comprising a shell (1; 21; 41; 61) surrounding the foot and an upper cuff (2; 22; 42; 62) articulated to the shell, comprising a device for fastening and unfastening the upper cuff relative to the shell, this device being connected to a fastening and unfastening member by a cable (10; 30; 50; 70), this fastening and unfastening device being in a first, fastened, configuration when the fastening and unfastening member is in a first position in which the upper cuff is kept in a predefined inclined position relative to the shell, and in a second, unfastened, configuration when the fastening and unfastening member is in a second position in which the upper cuff is able to move relative to the shell so that it can be stood up straight, wherein the connection between the cable (10; 30; 50; 70) and the boot fastening and unfastening member is such that moving the fastening and unfastening member from the first to the second position introduces tension into the cable, this cable being directly connected to a

Abstract: A ski-boot assembly with a rigid upper, an incomplete sole of the upper, and a front and/or rear means for cooperation with a removable sole assembly. A first removable sole assembly includes at least one curb part and a bearing plat; and a cooperation means that complements the front and/or rear cooperation means of the incomplete sole to form a boot with a sole whose configuration corresponds to standard ISO 5355 for Alpine ski-boots. A second removable sole assembly has at least one curb part and a sole cooperation means that complements the front and/or rear cooperation means of the incomplete sole to form a boot with a sole whose configuration corresponds substantially to standard ISO 9523 for touring boots. A locking means locks the first or the second removable sole assembly under the incomplete sole of the upper and includes a manual actuating means.

Abstract: A boot assembly comprising a rigid upper, of the ski-boot type, provided with an incomplete sole of the upper (1; 21; 21?; 21?) and comprising at the front and/or rear end, in its lower part, a front and/or rear means for cooperation with a removable sole assembly (11; 31; 31?; 31?), which comprises: a first removable sole assembly comprising at least one curb part and a bearing plate and a cooperation means (14; 34; 34?; 34?) that complements the front and/or rear cooperation means of the incomplete sole, capable of completing the incomplete sole of the upper in order to form a boot with a sole whose configuration corresponds to standard ISO 5355 for Alpine ski-boots; a second removable sole assembly comprising at least one curb part and a sole cooperation means (14; 34; 34?; 34?) that complements the front and/or rear cooperation means of the incomplete sole, capable of completing the incomplete sole of the upper in order to form a boot with a sole whose configuration corresponds substantially to standard I

Abstract: The brake device (30) for a lace (2), of a boot (31), sliding in a base part (1) linked to the boot (31), comprises a lever (3) articulated on the base part (1), returned by an elastic means (11) into a position of contact with the lace (2) preventing the sliding of the lace (2) in one direction by pressing action. The lever (3) has holding means (15, 16) enabling it to maintain a second, stable position allowing the sliding of the lace (2) in both directions, thus making the action required for opening the boot more convenient.
