Abstract

The invention disclosed relates to a method of producing a footwear last including the steps of forming rough castings of toe and heel portions (3, 2) of the last, separately maching such portions in an automatic computer operated, three-di­ mensional milling machine in accordance with a predetermined pattern, and connecting the toe and heel portions together. Thus, consistently accurate lasts can be produced.
