Abstract
The present invention provides a rubber footwear vulcanizate to which there may be separately affixed an outsole. The vulcanizate may be suitably manufactured from an assembly of an uncured rubber upper, insole, welt and a vulcanized midsole base article. The inner and outer surfaces of the midsole base article may be suitably roughened and the surface interfacing the uncured assemblage precoated with an uncured rubber. The assembled uncured rubber footwear components may be vulcanized into a vulcanizate footwear product of a unitary construction. The outer surface midsole surface permits a wide variety of compositionally differing outer soles to be separately secured thereto.
