Abstract
Method for producing soles for shoes, which initially includes the production, by molding, of a sole that has a perimetric ridge that protrudes downwards. The sole is then placed on a plunger of a mold that has a head which is shaped complementarily with respect to the lower surface of the sole and with respect to the ridge and in which there is a recess for containing the ridge and a gap for the intended flow of a second material to be injected. The last step consists in trimming the flash, which has an intended consistency.
