It's been awhile since I've learned something that got me this excited. I started running when I was 12 and been doing it off and on since then. I've always had issues with my shoe lace getting undone. Sometimes even with double knotting it. Anyway, I saw this video on Runners World that shows how to properly tie your shoes. I've always been told it's because I have cheap shoe laces. Anyway, it may not be that exciting to you (pun not intended). But for me, I feel great that my shoes won't untie any more.
