It's worth noting that 9(!) world records in track and field were set in 2020 (https://trackandfieldnews.com/records/mens-world-records/). Two of those were not on the track (pole vault, shot), and thee were set by a single individual (Cheptegei). I'm too lazy to try to dig up and chart the historical record progressions, but that does seem like a fair blip.
Myself, and virtually every competitive runner that I know at the amateur level, has invested in so called "super shoes" from one of the various manufacturers, with impressive (relative) results- generally, everyone has PR'd since the switch. Aside from that small sample set, numerous other studies have shown that the shoes deliver: - https://www.nytimes.com/interactive/2019/12/13/upshot/nike-v... - https://link.springer.com/article/10.1007/s40279-018-1024-z
At the end of the day, none of these shoes is actually giving you any energy for free- they're just much less lossy than the previous generation of shoes. This feels like the right direction of progress to me.
