Many years ago I tied my shoes with something called Perry's Perpectual knot[1][2], and then haven't had to retie my shoes since.

At worst the knot will get a bit loose from time to time (like maybe once a year), and then it takes a few seconds to tighten it again.

I expect my shoes will fall apart (they're already pretty old) before this knot unties.

You can also tie your laces with a reef knot which has no loops to catch on anything and untie.

If you're wearing hiking boots, you can go once around the back to reduce the lace lengths and then make the knot.

I’ve been using reef knot with extra turns (looks like the so called “surgeons” knot, but the top part also has extra turns), and can second the suggestion. it never has loosened or caught on something. also, because of extra turns, it never jams and can be easily untied even with one hand. just have to use shorter laces.
