Abstract
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.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
78 words
A method of making an article of footwear, comprising the steps of: (a) partially forming the article so as to comprise at least an upper lasted to a first insole; (b) arranging the partially formed article to fully expose the upper surface of the first insole by turning the partially formed article inside out; (c) moulding a second insole of elastomeric material onto the exposed surface of the first insole; and (d) applying an outsole to the article.
Claim 2
Independent Claim
78 words
A method of making an article of footwear, comprising the steps of: (a) partially forming the article so as to comprise at least an upper lasted to a first insole; (b) arranging the partially formed article to fully expose the upper surface of the first insole by turning the partially formed article inside out; (c) moulding a second insole of elastomeric material onto the exposed surface of the first insole; and (d) applying an outsole to the article.
Claim 3
Dependent Claim
18 words
The method of claim 1, wherein the outsole of step (d) is applied before steps (b) and (c).
Claim 4
Dependent Claim
13 words
The method of claim 1, wherein the second insole is of visco-elastic material.
Claim 5
Dependent Claim
24 words
The method of claim 1, wherein the thickness of the second insole is at least 3 mm in a heel portion of the article.
Claim 6
Dependent Claim
46 words

Claim 7
Dependent Claim
34 words
The method of claim 1 wherein step (c) comprises introducing a mouldable liquid composition for forming the elastomeric material into a mould cavity which is closed by the exposed surface of the lasting insole.
Claim 8
Dependent Claim
75 words
The method of claim 1, wherein the outsole of step (d) is applied before steps (b) and (c), wherein the second insole is of visco-elastic material, wherein the thickness of the second insole is at least 3 mm in a heel portion of the article, and wherein step (c) comprises introducing a mouldable liquid composition for forming the elastomeric material into a mould cavity which is closed by the exposed surface of the lasting insole.
