Patent attributes
An article of footwear having an upper, an outsole, and a midsole. The midsole defines a plurality of upper and lower channels intersecting in a waffled construction to define openings. The channels and openings allow passage of water from the interior of the article of footwear. The upper channels extend across the upper half of the midsole in one direction and the lower channels extend across the bottom half of the midsole in another direction. The channels are of sufficient depth so that the upper and lower channels intersect one another to define the openings through which the water may pass from the upper channels to the lower channels. The outsole forms the wear surface and covers a majority of the undersurface of the midsole, preferably defining a plurality of outlets or ports through which water may drain from the bottom of the shoe.
