Abstract
Abstract In an athletic shoe, a system for conveying air into the shoe in which an air reservoir in the resilient outsole assembly is open to a first transverse air channel which opens in turn to the surrounding air, a longitudinal air slot in the outsole assembly is open to the air reservoir, a first vertical hole in the top of the outsole assembly is open to the air slot and to a second vertical air hole in the insole board, the second vertical hole in turn is open to an air channel in the bottom of the slipsole, and the slipsole air channel is open to third vertical holes in the slipsole which open into the inside of the shoe under the user's foot; the air reservoir, air slot, first air holes and second air holes can lie on the midline of the sole assembly; and the slipsole air channels can be arranged in a grid covering the entire bottom of the slipsole with the first air holes, second air holes and third air holes arranged at the intersection points on the grid.

Claim 4
Dependent Claim
126 words
The shoe of claim 1 in which said outsole assembly comprises a midsole having its top surface attached to said insole board, a heel wedge extending at least half way from the back end of said shoe to the front end of said shoe, said heel wedge having its top surface attached to the bottom surface of said midsole, and a sole cover having its bottom surface touching the ground and having its top surface attached to the bottom surface of said heel wedge and to a portion of the bottom surface of said midsole, said air reservoir is cut through said heel wedge and said midsole, said air slot is cut through said heel wedge, and said first air hole is cut through said midsole.
Claim 5
Dependent Claim
