They’re very good for the sport though? Modern shoes allow runners to train more, which is one of the primary reasons we’ve seen world records get absolutely slammed since they were introduced. Just look at how may people can consistently run 100+ mile weeks with modern shoes vs before.

Is that good in itself though? Imagine if it was allowed to compete with full blown jumping stilts.

If you care about the sport and want to see people running even faster, yes.

Anecdotally we see more injuries in the form of bone stress than we used to, because modern shoes allow for greater training loads that aren’t quite as hard bounded by muscle tolerance as flats but without seeing any data I suspect the balance of injury has shifted rather than the general incidence of injuries.
