Abstract
A vented shoe having a conventional upper. An outer sole of flexible compressible material engages the periphery of the upper. A series of fluid passages extend through the outer sole from concavities formed in the outer surface of the outer sole. These fluid passages are continuous with larger openings formed in a filler overlying the inner surface of the outer sole, and with holes formed in the inner sole. The concavities are preferably formed and defined by annular grooves extending inwardly from the outer surface of the outer sole in a regular repeat pattern. Preferably ribs are formed on the outer surface of the outer sole coaxial with the concavities.
