ABSTRACT:
This invention relates to a method of making boots for aquatic activities, more particularly for underwater diving. The method consists in the steps of forming a sock from a sheet of cellular elastomeric material and adhering an outsole assembly, including unvulcanized non-cellular rubber composition, to the sole portion and to the adjacent part of the upper of the sock all around the sole portion; placing the resulting unit in an oven; and vulcanizing under pressure said outsole assembly in situ on said sock at a maximum temperature below the degrading temperature of the cellular elastomeric material of the sock.
