We often hear that humans are creatures of habit and routine. Frankly, as long as you're comfortable and content with the outcome, there is nothing wrong with doing the same thing over and over.

Still, there are times when we get too caught up in our ways and we fail to realize that there are other ways we could be performing some of our everyday tasks.

Take tying your shoelaces, for example. Most of us have been taught to do it in a specific way (my parents were proponents of the bunny ears method) and chances are we're going to be doing it exactly the way we learned it for the rest of our lives.

Since we're on the topic of shoelaces, there's something else that so many people ignore even though it is one the of the most useful features on certain shoe styles, especially sneakers.

Have you ever noticed that there are two holes at the very top of most sneakers? You probably have but just used them to tie your laces higher or ignored them anyway because you didn't think they were useful.

Well, they're not there for decoration and can come in handy if you're someone who walks or runs a lot in sneakers.

The holes exist so you can create a "heel lock" or "runner's loop," a lace technique used to prevent blisters by holding the back of your foot in place. Isn't it neat?

Obviously, the heel lock isn't anything new as experienced runners have been doing the trick, but there are still many people who had no idea this was something that could be done.

Even if your shoes already fit well, give the heel lock a try anyway because it could make a difference and save you from the pain that blisters bring and annoying bandaids that don't stay on for too long.

You can watch the video below to get a better idea of how the heel lock is done.
