![]() For the bow, make some loops and pull the one in your right hand behind the one in your left hand. ![]() Then pull the left lace over the right lace, then under and through. Here’s how to do it: Pull the right lace over left lace, then pull it under and through. (Though there’s no shame in that!) If you want to keep wearing your favorite running shoes or Air Jordans, you’ll be well served by learning to tie a square-knot bow. Here’s the good news: There’s a solution, and no, it’s not reverting to Velcro. ![]() If physics is not your bag, here’s a video that will help you visualize the phenomenon: “It’s unpredictable but when it happens, it’s in two or three strides,” O’Reilly says. With just a few strides and stomps, the lace comes undone. In between, each time the leg swings forward, the extra lace gets pulled back and forth, loosening the knot even more. O’Reilly and his team found that a runner’s foot strikes the ground at seven times the force of gravity, and each time the shoe hits the ground, the more the bows of your laces get jostled loose. Oliver O’Reilly, a professor of mechanical engineering, wanted to take a closer look at the actions we take when we run, so he put two assistants on treadmills and also employed a mechanical leg that would stomp on the ground, according to The Guardian. This phenomenon was put to the test in a study at the University of California at Berkeley. In other words, the moment you start running, the clock is ticking on your safety. ![]() It can happen suddenly - even if your laces have been secure for hours. Yes, scientists are studying this stuff, and what they’ve found is that the traditional method for tying shoes comes undone due to friction and movement. It’s known by many names - bunny ears loop, swoop, and pull and “the Granny knot” - but the truth is that the way most people learned to tie their shoes is inefficient and scientifically inferior. Here’s another thing your parents and teachers misled you about: tying your shoes. Don’t worry, we’re here to get you in the loop. ![]()
