摘要： A footwear article is formed according to a process that includes the steps of: forming a sheet including a rubber outsole material; forming an outsole component by passing the sheet through an extruder or calendar machine; applying a vulcanizing accelerant to the outsole component by dipping the outsole component in a liquid bath; forming a plurality of rubber outsoles from the outsole component by cutting the outsole component into the plurality of rubber outsoles; incorporating each of the plurality of rubber outsoles into the footwear article; and vulcanizing the footwear article. The vulcanizing accelerant includes a dithiocarbamate compound. The footwear article includes the rubber outsole, an insole and an upper. The vulcanizing accelerant allows the step of vulcanizing the footwear article to be performed substantially faster as compared to conventional footwear vulcanization methods.
