In one example, a ski boot includes a plastic shell, a boot liner partly received within the plastic shell, and the boot liner including a tongue having an upper edge, and a dynamic support strap. The dynamic support strap includes a band connected to the plastic shell, and a restraint element connected to the band, the restraint element including a wall and a lip that together define an undercut area behind the wall, and the undercut area is configured and arranged to receive a portion of the upper edge of the tongue when the restraint element is operably positioned with respect to the tongue.

Ski boot comprising a rigid shell which is shaped so as to accommodate the foot of the user, and has a lower part structured to couple with a ski binding device; a rigid cuff which is shaped so as to surround the lower part of the leg of the user, and is pivotally jointed to the shell thus to be able to pivot about a rotation axis substantially perpendicular to the midplane of the boot, and shell closing means adapted to selectively tighten the shell on the foot of the user; the shell comprising a substantially basin-shaped casing which is superiorly provided with a main opening from which the leg of the user comes out, and with a longitudinal slit that branches from said main opening and extends along the casing towards the front tip of the shell; the shell closing means being placed at the longitudinal fissure.

In one example, a ski boot dynamic support strap includes a band configured to be connected to a ski boot, and a restraint element configured to be connected to the band. The restraint element includes a wall having an upper edge, and a lip that is connected to the upper edge of the wall and extends away from the wall. The lip and the wall collectively form an engagement portion that includes an undercut area, and the engagement portion is sized and configured to accommodate a portion of an upper edge of a tongue of a ski boot liner in the undercut area.
