try the new shoes with the inners they shoes came with, and also try the special inners in an old pair of runners, and see what happens.
if the 1st cures the issue you have been sold a dud - go ask for your money back! if the 2nd cures the issue, you have been sold the wrong shoes - go ask for your money back!
