Ever wonder what those extra shoelace holes are for at the very top of your athletic shoes? Or, never thought about it? Quick! Go grab your shoes! I took my workout shoes out of my gym bag and, sure enough, there are extra holes I’m not using.

A cool company by the name of Illumiseen put together this quick video to demonstrate how it works. Take a peek!
Cool, huh? The next time you’re at the gym or with your running group, impress your friends with this tip!
