OK here we go again...You all are going to think I am crazy again, but as I have posted when others have posed this question and the answer is simple, hair spray. Now that the laughing has stopped...seriously it works, good old fashioned aqua net works fine just don't go crazy spraying it on, just a little squirt on the laces before you tie them will work miracles. I have marched too many miles to count in ghilles but once I learned the hair spray trick fallen laces have become a thing of the past.
