Abstract: 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.
