For some reason I have a pair of sneakers that they will always untie way many more times than any other shoes that I ever had, no matter how hard you make the regular knot. No more!

So I have a simple alternative to tying my shoes that you can teach and learn easily. Knots are all about the number of turns or wraps, so when tying your shoes instead of crossing the laces over once, do it twice. When you wrap around the loop, do that twice too. You may have to try it to understand, but it is easy and readily understandable to anyone who can already tie their shoes. The best part is the way you tighten it down and untie are are exactly the same as you have always done. It almost never comes untied, but still releases easily.

I've been using this knot for years; I want to say since college (at least 10 years now). It's stupid fast to do once you learn it and it doesn't slip off ever.

Highly HIGHLY recommend learning it.

One other thing I've been doing lately is also to use bar lacing instead of cross lacing. A small change that makes shoes much more comfortable.

I'm curious about the physics involved to cause such an obvious and singular failure.

If anyone's playing with this you may find that after you tie the loops together they're sitting funny; you basically have to swap the sides the loops sit on!
