Abstract
An inflatable shoe insert assembly may have an elongated lower element formed of opposing, flexible, polymeric plies that are sealed together to define a tubular inflation chamber that is narrow and elongated and is configured to seal inflation fluid therein; a shoe-upper element formed of opposing, flexible, polymeric plies that are sealed together to define a shoe-upper inflation chamber configured to seal inflation fluid therein; wherein lower and upper inflation chambers are configured and dimensioned to fit together into a shoe and support each other in an installed position to cooperatively support and maintain the shape of the shoe upper.
Claims26
An inflatable shoe insert assembly, comprising:
- a lower element formed of opposing, flexible, polymeric plies that are sealed together along a seal pattern that defines an elongated inflation chamber configured to seal inflation fluid therein;
- and
- a shoe upper element formed of opposing, flexible, polymeric plies that are sealed together along a seal pattern that defines a shoe upper inflation chamber configured to seal inflation fluid therein;
- wherein the lower element and shoe upper inflation chambers are configured and dimensioned to fit together into a shoe and support each other in an installed position to cooperatively support and maintain a shape of the shoe upper.
An inflatable shoe upper insert, comprising:
- opposing, flexible, polymeric plies that are sealed together along a seal pattern that defines:
- one or more inflation chamber configured to seal an inflation fluid therein, the one or more inflation chamber including a plurality of inflation chamber regions, and
- a first hinge line that allows the chamber regions to be folded with respect to each other to fit within a shoe upper;
- wherein the inflated and folded insert is tapered to fit within and support a shape of the shoe upper.
