Perhaps take the ones that fit you best, with the right size toe box, to someone who can make custom insoles. Also, if the top of your foot is rubbing without your heel slipping, you likely have an instep too high for the shoe, or you are cranking the laces so tight to avoid heel slipping that you have effectively made the shoe too tight. If you haven't already, check out different lacing techniques to see what works best for you. http://www.fieggen.com/shoelace/locklacing.htm
