Abstract

A shoe fitted with an inflatable sole. One or more air valves joined to the shoe permit inflating the interior of the sole to a desired pressure of air proportional to the weight of the wearer of the shoe. The sole is formed of an upper liner joined to a lower liner along their respective common periphery, with a plurality of spaced resilient pegs joined between the said liners in the interior so as to maintain the said liners in alignment with the sole inflated, and to provide a uniform air pressure throughout the interior of the sole. Alternatively the sole may be formed of a solid section of flexible or elastomeric material formed with a plurality of intersecting through longitudinal and transverse cylindrical air passages joined to one or more valves.

Claims3

Dependent claims

A shoe comprising a shoe body and an inflatable sole, said inflatable sole comprising a sole assembly to which the said shoe body is attached, said sole assembly comprising an upper lining, a lower lining, means for attaching said linings to each other about their common periphery, flexible means to space said lower lining spaced apart from said upper lining so as to provide a continuous passageway for air along the length and width of said sole,

said flexible means consisting of a plurality of spaced flexible pegs, each peg being bonded to at least one of said linings and extending to the other, said pegs having an intermediate section of reduced cross-section relative to the end sections thereof;
and
an inlet valve connected to said continuous passageway so that the passageway may be inflated with air under a common pressure for the length and width of the sole.
