Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
158 words
A shoe ventilation apparatus providing ventilation while the shoe is worn, comprising: flexible, cushion, mid-sole and uppers bonded together and to an out-sole; said bonded combination removably fitted with an in-sole; said out-sole providing branching air-channel means, and air exhaust channel means open to ambient air; said air-channel means corresponding to a series of corresponding air passages means bored through said in-sole, cushion and uppers; said air passage means providing egress for air from the interior of said shoe; said air channel means removably fitted with air-exhausting means at their junction with said air exhaust channel means; in which said cushion means are composed of an elastomeric, gas impermeable foam, and said out-sole means are composed of an elastomeric, gas impermeable material; and in which said mid-sole and cushion means have air-exhauster access ports therein, said ports having removable cover means fitted therein; and in whch said air exhaust channel means are perpendicular to said air channel means.
Claim 2
Dependent Claim
158 words
A shoe ventilation apparatus providing ventilation while the shoe is worn, comprising: flexible, cushion, mid-sole and uppers bonded together and to an out-sole; said bonded combination removably fitted with an in-sole; said out-sole providing branching air-channel means, and air exhaust channel means open to ambient air; said air-channel means corresponding to a series of corresponding air passages means bored through said in-sole, cushion and uppers; said air passage means providing egress for air from the interior of said shoe; said air channel means removably fitted with air-exhausting means at their junction with said air exhaust channel means; in which said cushion means are composed of an elastomeric, gas impermeable foam, and said out-sole means are composed of an elastomeric, gas impermeable material; and in which said mid-sole and cushion means have air-exhauster access ports therein, said ports having removable cover means fitted therein; and in whch said air exhaust channel means are perpendicular to said air channel means.
Claim 3
Dependent Claim
170 words
A shoe ventilation apparatus providing ventilation while high top shoes or boots are worn, comprising: flexible, cushion and uppers bonded together and to an out-sole; said bonded combination removably fitted with an in-sole; said out-sole providing branching air-channel means, and air exhaust channel means open to ambient air; said air-channel means corresponding to a series of corresponding air passages means bored through said in-sole, cushion and uppers; said air passage means providing egress for air from the interior of said shoe; said air channel means removably fitted with air-exhausting means at their junction with said air exhaust channel means; in which said cushion means are composed of an elastomeric, gas impermeable foam, and said out-sole means are composed of an elastomeric, gas impermeable material; and in which said cushion means have air-exhauster access ports therein, said port having removable cover means fitted therein; and in whch said air exhaust channel means are perpendicular to said air channel means and extending vertically therefrom along the extended portion of the shoe upper.
