Nathan’s high-performance Run Laces are ultra-grippy, elastic and quick and easy to use. While normal shoe laces often come loose on their own, Run Laces stay exactly where you want them. When you slip into your shoes, you no longer have to worry if the lacing is too tight or too loose. Simply adjust once. 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.
