Abstract
Provided is an inflatable shoe insert for inserting in a shoe. The insert comprises first and second web plies that are sealed together at a plurality of seals that define an air chamber. The air chamber includes a front region having a toe expansion region uninterrupted by seals over an area so that when fully inflated, the front region expands to a height and medial-lateral width to support the shoe upper against collapsing. The air chamber further includes a retention portion having a region in which the seals are spaced closer together than in the toe expansion region so that when fully inflated, the retention portion expands to a medial-lateral width that is smaller than that in the toe expansion region, the retention portion having an anterior-posterior length that reaches the heel of the shoe to retain the front region in the toe box by pressure against the heel.
