I don't know about you, but I've always wondered about the purpose of that extra shoelace hole on my tennis shoes.  You know the one...at the top, kinda off to the side.  What the heck's it for?  Decoration?  Over-achieving hole maker?  Mistake?

No.  There's really a reason for this extra space...other than to confuse me and make me wonder about things.  This lace hole can keep your shoes tighter on your heels, preventing blisters.

Follow this simple how-to video and you'll reduce (or eliminate) heel blisters while running, jogging, playing tennis, or whatever you do in your favorite shoes!
