I've tried a couple of these "better" shoe tying knots and have never had the patience to learn them to the point they become habitual. So I can spend 2 seconds tying a shoelace the way I learned when I was 5 years old, or I can spend 5 minutes fumbling with some other knot. I go with what works for me. Optimizing the time I spend tying my shoes just isn't anywhere on the radar of things that would have a worthwhile ROI.

I've been 100% slip-ons for years.

There are laces designed to convert a shoe meant for regular laces into a slip-on, such as https://www.locklaces.com/

I've used them and they worked pretty well.
