Abstract
Abstract An air shoe has a sole having a plurality of channels longitudinally and laterally in the upper surface of the sole, forming a multiplicity of sections at least partially surrounded by such channels. This sectionalized structure improves air flow beneath the wearer's foot as he walks, runs, or exercises, increases massagic action, and makes the shoe lighter and more flexible. An air flow slip sole is also placed on the sectioned sole, simultaneously contacting both the channels and the wearer's foot to increase air flow to the foot.

Total Claims: 9
Claim 1
Independent Claim
341 words
In an air shoe having a shoe upper and a sole body joined to the upper, a bottom surface on said sole body having a predetermined tread design on said surface, an upper surface on said sole body, a ventilation channel network on the upper surface of said sole body consisting of a plurality of longitudinal channels in said sole body contiguous with and opening at said upper surface extending from a position within the heel portion of said sole body to a position within the ball portion of said sole body and extending a substantial distance into the ball portion of said sole body, a multiplicity of lateral channels in said sole body contiguous with and opening at said upper surface and crossing said longitudinal channels to divide said upper surface into a multiplicity of individual sections, each section at least partially surrounded by channels, at least one of said lateral channels being in said heel portion, a plurality of said channels being in the ball portion and at least one of said channels being in the instep portion of said sole body, to form an intercommunicating network of channels as an air passage to the various longitudinal and lateral channels across substantially the full area of said sole, including both said heel portion and substantially the full area of said ball portion and to provide massagic action to a wearer's foot as the foot presses on and releases pressure from said sole body, the channel at said instep portion leading from said intercommunicating channel network and terminating in an enlarged mouth at said instep location, said network of channels being protected against lateral exits and entrances for air flow between said instep portion and a location fully within said ball portion of said sole body, whereby air from said instep portion of said sole body is conveyed into said ball portion as said wearer of said shoe exercises. said mouth having a bottom surface declining downwardly from said channel to an open end at the edge of said sole.
Claim 2
Dependent Claim
341 words
In an air shoe having a shoe upper and a sole body joined to the upper, a bottom surface on said sole body having a predetermined tread design on said surface, an upper surface on said sole body, a ventilation channel network on the upper surface of said sole body consisting of a plurality of longitudinal channels in said sole body contiguous with and opening at said upper surface extending from a position within the heel portion of said sole body to a position within the ball portion of said sole body and extending a substantial distance into the ball portion of said sole body, a multiplicity of lateral channels in said sole body contiguous with and opening at said upper surface and crossing said longitudinal channels to divide said upper surface into a multiplicity of individual sections, each section at least partially surrounded by channels, at least one of said lateral channels being in said heel portion, a plurality of said channels being in the ball portion and at least one of said channels being in the instep portion of said sole body, to form an intercommunicating network of channels as an air passage to the various longitudinal and lateral channels across substantially the full area of said sole, including both said heel portion and substantially the full area of said ball portion and to provide massagic action to a wearer's foot as the foot presses on and releases pressure from said sole body, the channel at said instep portion leading from said intercommunicating channel network and terminating in an enlarged mouth at said instep location, said network of channels being protected against lateral exits and entrances for air flow between said instep portion and a location fully within said ball portion of said sole body, whereby air from said instep portion of said sole body is conveyed into said ball portion as said wearer of said shoe exercises. said mouth having a bottom surface declining downwardly from said channel to an open end at the edge of said sole.
Claim 3
Dependent Claim
88 words
A shoe according to claim 1 having a porous inner sole located on the upper surface of said sole body contiguous with said network of channels and extending beyond the edges of the upper surface of said sole body, said inner sole providing 5 lasting between said sole body and said shoe upper and forming a continuous air chamber communicating between the outside air and a wearer's foot throughout the area on the upper surface of said sole body including substantially the entire ball portion of the foot.
Claim 4
Dependent Claim
191 words
In a shoe, in combination, a sole body having a predetermined tread design on its bottom surface, an upper surface on said sole body, a multiplicity of longitudinal and lateral channels in said upper surface forming a network of intercommunicating channels and dividing said upper surface into a multiplicity of sections, each section at least partially surrounded by said channels, at least a first one of said lateral channels being at the instep portion of said sole body and leading to an external enlarged mouth at said instep portion, the lateral channels other than said first lateral channels terminating within said sole area and communicating solely with said network of channels, and an inner slip sole having an upper mesh layer adapted to contact a wearer's foot and having a lower foam layer positioned to communicate with said network of channels, an exterior frame on said slip sole attached to the shoe upper to provide lasting thereto and attached to said lower foam layer, the communicating network of channels and the foam layer of the slip sole being adapted to provide air flow to and across substantially the entire foot area.
Claim 5
Dependent Claim
191 words
In a shoe, in combination, a sole body having a predetermined tread design on its bottom surface, an upper surface on said sole body, a multiplicity of longitudinal and lateral channels in said upper surface forming a network of intercommunicating channels and dividing said upper surface into a multiplicity of sections, each section at least partially surrounded by said channels, at least a first one of said lateral channels being at the instep portion of said sole body and leading to an external enlarged mouth at said instep portion, the lateral channels other than said first lateral channels terminating within said sole area and communicating solely with said network of channels, and an inner slip sole having an upper mesh layer adapted to contact a wearer's foot and having a lower foam layer positioned to communicate with said network of channels, an exterior frame on said slip sole attached to the shoe upper to provide lasting thereto and attached to said lower foam layer, the communicating network of channels and the foam layer of the slip sole being adapted to provide air flow to and across substantially the entire foot area.
