Who is everyone? Outside of Balmain, I am not sure I've seen many use the strap? And Creative Recs aren't even the first to use those straps, Creative Recs designs are mostly stolen from other designers to begin with.
And by the way, it isn't pointless, it helps secure/tighten the shoes to your feet. Nike trainers use the same straps to help make it feel locked to your foot, it is merely a deign aesthetic for these designer shoes but it isn't pointless.
