Our Nathan performance Run Laces are ultra-grippy, elastic and easy and quick to use. While normal shoelaces often loosen on their own, the Nathan Run Laces stay exactly where you want them. When you slip into your shoes, you no longer have to worry about whether the lacing is too tight or too loose. Adjusting once is sufficient. The ideal solution not only for runners or triathletes who want to save time in the changing area, but also for walkers, children and the elderly.
