Something`s not right here....figuring it out is another thing. Is there a build-up on the lace itself which is not being removed with normal cleaning ? In my experience of glues, they don`t `go off`/ out -of-date ....that`s been my experience and I haven`t heard of someone saying it`s an issue [ I may, of course be corrected on that point] It may be time to try a different glue..it`s possible that maybe your body-chemistry may have altered somewhat with the warmer weather and is now having a detrimental effect on your glue.... are you sweating more than normal? If so, that may be the issue..... the glue I use is available in the UK ...link here ...it`s the one at the bottom-left for 21£ [`Tracksafe`] http://www.direct-sites.co.uk/colour_rin...sories.htm Hope the interview goes successfully tomorrow.......cheers, Paul.
