Milan Classic SA manufactures shoes in Almansa with Berwick 1707, through the process that Charles Goodyear Jr. patented. 

Controlling the production vertically through a complex industrial organization, so that each and every one of the phases in shoe manufacturing, even those that are normally outsourced, such as the construction of the heel or the production of the sole, are developed in the same factory - this favours cost containment and quality control.
