I believe the general risk of using the minimal racing flats of the past were a well known market wide understanding. There is no risk articulated anywhere about usage of the carbon plated shoes (if any, it still would need to be quantified, but there are enough people who have had issues with them that it’s not nothing). But they also make fast-er running accessible to everyone (at least faster than traditional race flats. But its not long ago that most of the elite field was on shoes like you showed (image of Rio 2016 men’s marathon, not sure how many of the Nikes were proto Nike carbon, but pretty sure Galen Rupp was on them)
