The researchers found that different knot-tying techniques, types of laces and levels of knot tightness all factor into how long it takes shoelaces to come undone. A really tight double knot ...

The undone shoelaces of Bralon Taplin of Grenada can be seen as he competes in the men's 400m semifinals during the 2016 Rio Olympics at the Olympic Stadium in Rio de Janeiro, Brazil, Aug. 13, 2016.

The scientific evidence is now clear: we all tie our shoelaces wrong. America’s epidemic of untied shoes can be blamed in part on faulty shoe-tying technique, according to rigorous experiments ...

The knot stretches and then relaxes in response to that force. As the knot loosens, the swinging leg applies an inertial force on the free ends of the laces, which rapidly leads to a failure of the ...

“Some laces might be better than others for tying knots, but the fundamental mechanics causing them to fail is the same, we believe,” Gregg says. Of course, sometimes laces don’t come untied.

In order to tie your shoes, there's a simple knot that almost all of us learn how to make when we're small children: a "criss-cross and tuck" part, followed by a "loop-and-pull" part. That simple ...

As the knot is shaken looser by that force, the ends of the laces swing back and forth as the person wearing the shoelaces moves their legs. That force effectively puts pressure on the ends of the ...

Shoes come untied? Professor Shoelace shows what knot to do 02:17. SACRAMENTO - Many of us remember the long-ago day we learned to tie our own shoes. "I learned how to tie my shoes when I was 3 ...

I’m a surgeon — the best way to tie your shoes is like blood vessels By . Andrew Court. Published May 31, 2023. ... He then loops the laces in a single knot, completing the process.

A new study shows why your shoelaces may keep coming untied. A better understanding of knot mechanics is needed for sharper insight into how knotted structures fail under a variety of forces.
