Stokesy Mar 2021 7:53am, 6 Mar 2021 184 posts	0 Stokesy Disappointed to see races still being cancelled as far forward as May and pushed to next year - a couple I had been keeping an eye on have recently bailed out. Looks like we could be in for another Summer of time trials and motor racing circuits!

Basically the Nike carbon plate, together with the foam propells you forward further than other brands. This is just one guy, so not very scientifically significant, have there been other studies showing the same thing??
depeche_mould Mar 2021 8:51am, 27 Mar 2021 22 posts	0 depeche_mould Interestingly Damo, as you might know all the research suggests most of the biomechanical advantage of these new shoes come from the foam (in the case of next percent it's the pebax) and not the plate itself -- which gives only tiny advantages. I don't know where he's got this increased stride length figure from either. Couldn't find anything online!
fuzzyduck79 Mar 2021 10:32am, 27 Mar 2021 120 posts	0 fuzzyduck79 Your stride length can be worked out from cadence and distance, which most fitness devices pick up Was told that Nike tech people said (to a decent runner I know) their data suggests it's nearly all foam causing the increase in speed. Carbon plate maybe stabilises the foot/ankle and stops shoe bending too much in the middle, but it's all a bit handwavey on that front. Stick a carbon plate in an old racing flat and I think it will do next to nothing to change your speed, it's all about the bouncy Pebax More Pebax, more free speed - as seen with the sub 2 thing
J2R Mar 2021 5:39pm, 27 Mar 2021 3,520 posts	0 J2R This is what I've heard, too. It's the foam that's doing the job, and the carbon plate makes it possible by preventing deformation of the foam. Given the success of the Adidas shoes in the Valencia HM in December, it's obviously not just Pebax which does this.
