Embodiment Construction

[0039]Referring now to the drawings, wherein like reference numerals designate identical or corresponding parts throughout the several views, and more particularly to FIG. 1 thereof, there is illustrated

[0040]The present invention is directed to a shoe with a pneumatic inflating device disposed therein. The general schematic of the shoe inflating arrangement is shown in FIG. 1 and includes three bladder sets. However, it will be apparent that the arrangement is adaptable to any plurality of bladder sets. The arrangement includes a pump 12 with an inlet 14 and an outlet 16. Outlet 16 is connected to a flow switching device 18 at a flow switching input 20. Flow switching device 18 operates as a selective valve which allows air flow into at least two outlets, the preferred embodiment having a first outlet 22, a second outlet 24, and a third outlet 26. Each outlet 22, 24, and 26 is connected to a corresponding conduit 28, 30, and 32. Each conduit 28, 30, and 32 is associated with corres...

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.
