Abstract: In a device for improving the seal between the cuff (3) of a ski boot (1) or an inner (5) and the leg with a band (6) mounted on boot (1) or on inner (5), said band surrounding boot (1) and the leg and being closable beltwise, band (6) has at least one coupling member (13, 14) for optional mounting on cuff (3) or inner (5) of boot (1), said member being connectable with a matching computing member (11, 14) on cuff (3) or inner (5) of boot (1).

Abstract: In a device for holding a foot in a ski boot with a tiltable cuff (2), a shell (3) overlapping the instep, and a projection (8) overlapping the heel area inside shell (3) or cuff (2), a flexible tensioning member (9) is disposed between cuff (2) or shell (3) and projection (8) overlapping the heel area, the free ends (10, 14) of said member running in the direction of the toe of the boot and mounted on shell (3) at a distance from the heel. One free end (14) of tensioning member (9) is then mounted in a lengthwise-adjustable manner, and this end or the other free end (10) of tensioning member (9) is mounted on a closing flap (11) on the front of the boot, especially on a component (6) which bears the attachment point for a toggle buckle (5).
