The lock lace method (I forget the "official" name) is also a huge game changer for footwear. Especially boots and taller stuff.

You can use it to have looser / tigher "zones" or specific areas and optimise the fit of well fitting shoes and make shoes that dont fit temporarily useable. Also great for hiking when you might want a slightly looser toebox for general use and then tighten everything down when switching to a steep downhill sections.

Also a game changer for snowboard boots and why I prefer traditional laces vs speed laces or boa systems. I can see why they are popular there though - most people wont be using fancier lacing techniques and have two adjustable zones (speed laces) is better than none.
