I'm not so sure, an elite female triathlete I know that takes part in a local 5k series, has for years run no faster than 16:45 in Adidas. Then she switched to Vaporfly Next%s and boom 16:20s week in week out and I can't stand Nike. Though there may be other models in the pipeline that are just as good that aren't getting coverage. There shows are faster.
Shoes were faster in the 1970s before the RW shoe rankings, from whence shoes were thereafter brutalized with foam, all sorts of gimmicks, and advertisements to make more $$$ - and the shoes kept getting worse, harder to train and run fast in, also precipitating more injuries.
Making simple shoes that are much faster than what's been around for the last few decades should not be so difficult to accomplish.
