Initial Update after 1 month:  Using on a set of boots (Fryes).  Looks nice, sized correctly - stays tied.  Shows slight amount of wear after 1 month.  Will update to see how long they last (whether they fray and snap or they just get raggeddy looking but keep working).  Prior laces I had (not original laces) - worked great and only got replaced after two years of use - because the ends started to finally fray.  Hopefully these can last at least a year without the center of the laces getting raggeddy.
