Whatever they do, they cant make the new rule such that it bans any current shoe. Or they could, but that would mean records set in that shoe would have to fall away.
I agree with your sentiment completely. But historically sport governing bodies have repeatedly shifted the goal posts.
UCI are prime examples of moving the technical goals every time the Anglophone world innovates something. No superman. No crouched position. Saddle totally flat. No dimples on shirts. Sock height limits (FFS) Etc etc.
But other sports too. Eg. Javalin specs changed circa 20 years ago to reduce the distance thrown (ok for good reason- no skewering spectators at meets as throws were reaching the ends of infields).
Motorsport- constantly.
