I switched to the secure knot after finding this site a few years ago https://www.fieggen.com/shoelace/secureknot.htm

It's really excellent, my shoes never come untied and I don't have to double-knot

I have been using this knot for years. As you say, it never comes undone. Not a single time in 6 years or so.
