I learned about that knot (and about how the directionality of the traditional shoelace knot we learn matters for how secure it is) a year or two ago from HN. Unfortunately, I probably haven't worn anything with laces in more than 9 months. I'm a flip-flip kinda guy most the time, and when you combine that with me getting some boat shoes a while back and shelter-in-place...

Cheers. I was wondering whether you only needed one footwear item. I guessed that in that case you might call that item a "flip-flip" since it wouldn't alternate.
