So I've posted many times on this topic with the same point of view.
Road running product pretty substantial impact but ultimately a massive spectrum of "benefit" dependent on the runner. Surface run on (hard and non compliant) and distance of race (typically much longer than track) compound the benefits making them "greater".
Track product still a massive unknown. Probably why no brand has made quantifiable claims like they did for road racing product. Compliant track surface and in general much shorter events mean the benefits most likely come from reduction in impact fatigue during workouts/preparation on the track. Still a benefit but not even close to the same level as on the road.
And of course, end of the day, none of these products are generating anything (force, ability, potential) - they are simply helping athletes more effectively reach their ultimate and inherent potentials. I mean technology jumps in other sports such as cycling (steel bikes through to now ultralite carbon etc) and golf (hickory shafted clubs with wooden heads through to now graphite shafts with titanium/carbon fiber heads) have had far greater performance impacts.
The problem in running is that it's such a unique sport in that it's one where you can measure yourself across the course of time because the field of competition is by in large consistent across that course of time (tracks, marathon courses etc) and this is where the "furore" comes from.
My theory for it is pretty simple. Runners and in particular distance runners have interesting mindsets. We always think we could have run faster than we did (in most cases that's the case) and we hate to think that others might do so based on anything other than the same type of hard work we put in. The only reason we get to this is because unlike many other sports, the only variable in performance is our own personal shape and a pair of shoes we put on our feet - that's it. Runners hate thinking that people train harder than they did or that people are simply more talented for a number of reasons - some learn to accept it and let go but many can't. I think this is why the community is so resistant to technology helping on any level. It's seen as "dirtying" the purity of the sport which we hold onto as a reflection of our efforts (sometimes careers) in it. I don't even believe we are in an era of the biggest innovation/tech jump in running (I believe going from leather and PU shoes to knitted textiles and EVA was far bigger) but people love picking and choosing the parts of the evidence and facts to support their agendas.
And I know this is the case because I once too was fresh off a competitive career and almost felt myself rooting against people running faster than I did based on my own disappointments/what-ifs/insecurities but that passed a long time ago. I love seeing this new "plateau" of performance - it's good to see and good for the sport. I also laugh at the fallacies I hear about "super" things such as "spring plates" and "magical carbon fibers" etc etc, mostly because I am fortunate enough to have some intricate knowledge on how this actually all works because of my career.
Long live the "super shoes" and congrats to those taking advantage of (finally) some new innovation and tech in this sport and industry.
