Abstract
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.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
102 words
A vented athletic shoe comprising: a shoe upper, an outersole of flexible compressible material engaging the periphery of said upper and having an outer surface and an inner surface, means forming a plurality of fluid passages through said outersole from said inner surface to said outer surface, and said outer surface formed with a plurality of concavities, each of said concavities respectively aligned with different ones of said passages and adapted to form a chamber from which air is forced into and through said passage associated with said chamber as the periphery of said chamber engages and is pressed toward a surface.
Claim 2
Dependent Claim
102 words
