A process for producing an ethylene vinyl acetate insole involves weighing molding compounds for manufacturing the ethylene vinyl acetate insole. The molding compounds are mixed and rolled by means of a roller so as to form a sheet material. The sheet material is cut into a plurality of elongated strips. A predetermined amount of the strips are placed into a first mold unit, which is heated and pressurized so as to form a partially foamed insole. The partially foamed insole is placed into a second mold unit, which is heated, pressurized, and cooled so as to form a completely foamed insole. The completely foamed insole is trimmed to form a finished ethylene vinyl acetate insole.
