Abstract
An anvil for supporting an outsole based upon an elastomeric compound, the outsole having a heel portion of greater thickness than the sole portion, during a process of imparting a multiplicity of slits to the outer surface of the heel and sole portions of said outsole. The anvil has a sole portion extending to a greater height than the heel portion of the anvil, whereby the multiplicity of slits may be imparted to the heel and sole portions of the outsole by a single reciprocating cutting blade in one continuous operation without removing the outsole from the anvil or changing the position of the outsole on the anvil. A method of imparting the multiplicity of slits to the outsole is also provided.
