ABSTRACT:
An article of footwear is made by partially forming the article so as to comprise at least an upper (11) lasted to a first insole (12), arranging the partially formed article to fully expose the upper (or inner) surface of the first insole, preferably by turning the partially formed article inside out, and moulding a shock absorbing or resilient second insole (15) of elastomeric, preferably visco-elastic, material onto the exposed surface of the lasting insole. An outsole (13) is applied to the article at some stage, preferably before the second insole is moulded in.
