I didn't know about this knot, but I'm pretty sure I tried it when I was kid, messing around with different ways to tie laces.

I tried it just now, and it's indeed very secure.

I almost always wear sneakers, and don't have any problem with laces getting untied, so I'll stick with the Ian Knot.

I will suggest this secure knot to my son, though.
