I switched to Ian's original shoelace knot about ten years ago. It's saved me something like four hours of shoelace time since then. Bloody brilliant.

I switched too and love it. It's arguably just a bit faster then the one I learned in childhood, but it's so much more reliable. I got couple of snickers I use daily and don't untie them at all, and the Ian's Knot [0] stays firmly knotted for months!

I learned it around 5 years ago and it just makes tying my shoes feel so effortless, I also feel like it holds on a little better than the previous knot I was using. It took me a while to get the mechanics down.
