The Extra Shoelace Hole Finally Explained [VIDEO]

You know that extra shoelace hole on the side of your shoe? I just found out it is more than just an extra shoelace hole.

I've run more miles than I can count. I've done 5k's, 10k's and a half marathon. I had no idea that I was tying my shoes all wrong.

The video explains how to prevent blisters with a "heel lock" or "lace lock." If you run to stay fit or just for fun, you'll probably need to watch the video a few different times to get it down, but once you do, you'll be like "where has this been my entire life?"
