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