I tried the Ian Knot, found it fiddly to tie. I use a standard knot by force of habit or when I can't stand having unties, or the laces are long, I use a Surgeons Knot.

The Surgeons Knot is just a standard shoelace tie with 2 slight modifications - when you overlap the 2 sides of the lace you tuck the lace under twice. This, like a Timber Hitch, creates much more contact area and thus much more friction.

I have (not from that site) switched the way I tie a standard knot as I was doing grannies instead of reef-knots. This seems to have prevented unwanted unties.

vouch for the surgeons knot. watched the ted video for correctly tying shoe laces. surgeon knot was only one more loop. i have shoes with rounded laces that comes undone easily, this fixed the problem.

I used the Ian Knot for a while, but then went back to one of the standard methods. The difficulty I had with the Ian Knot was when I wanted the laces to be tight. With the standard methods I was able to pull the laces tight, then keep the Starting Knot tight also as I tied the final loops. With the Ian Knot, it was hard to keep the Starting Knot tight whilst I tied the loops.

I find it weird how he calls himself the inventor. This knot is decades old if not centuries.

I concur. I'd always had problems with some tennis shoes with strings being short and thick, causing them to untie in the middle of a session. Has never been a problem since I learned that knot.

I've been using the Ian Knot for the past few years, never had a problem.

Seconded. Came to post this exactly.
