Abstract: A pneumatically cushioned shoe or shoe insert device including a plastic layer forming air bladders; a cloth layer covering a top surface of the plastic layer; a rubber layer covering a toe portion of a bottom surface of the plastic layer; a C shaped indentation on the plastic layer forming an arch region air bladder; and circle or oval shaped indentations forming interconnected air bladder regions having respective air bladders and including an inner heel, outer heel, and metatarsal air bladder regions. The rubber layer including cutting lines for sizing for regular or wide foot sizes and a lower thicker line defining a do not cut below region. The cloth layer including cutting lines for sizing for the other of regular or wide foot sizes. The air bladders pre-filled with air during manufacturing or filled with air by a user.

Abstract: A pneumatic inflation device disposed within the sole of a shoe and comprising a pump with integral air release valve and which is entirely within the sole, a pump actuator which is entirely within the sole when not in use, and an inflatable bladder which is entirely within the sole and is operatively connected to the pump. Such a device can include a mechanism to lock the pump actuator within the sole such that the mechanism's cap is flush with the outer wall of the sole and finger-operable to allow the shoe-wearer to easily operate the inflation device and release air therefrom.

Abstract: A pneumatically cushioned shoe or shoe insert including a plurality of regions, each region including a respective plurality of air bladders; each respective air bladder having a self-sealing valve disposed thereon and configured to allow air to enter the bladder through the valve while maintaining air pressure within the air bladder; and each self-sealing valve configured to allow air to escape through the valve via an air pump needle or via an integrated pump and release valve device.

Abstract: A bellows pneumatic system including a pneumatic inflating device (12) disposed within the sole of a shoe (100) which is comprised of a plurality of bladders or bladder sets within the sole of the shoe, each bladder being connected to a flow switching device (18) via conduits.

Abstract: A pneumatic inflating device disposed within the sole of a shoe includes a plurality of pairs of oppositely disposed hollow chambers within the sole of the shoe, a plurality of inflatable air cells, each air cell disposed within one of said hollow chambers, a pump assembly attached to the shoe, a plurality of tubes connecting the air cells to the pump assembly, means for restricting air flow out of the air cells, and means for releasing air from the pneumatic inflating device. The means for restricting air flow out of the air cells includes a nipple disposed at the end of each branch of the tubes. The means for releasing air from the pneumatic inflating device includes a release valve. The pneumatic inflating device can further include means for locking the pump assembly in a closed position.
