Those shoes are gonna sell like crazy now but it would be hilarious if they were to be found to have been giving an unfair advantage because of some mechanical property of the shoe.

what else could it possibly be if not that?

  Well, the marathon record has been broken 53 times since the early 1900s. So, there are a lot of factors at play. Better training, better nutrition, better tactics, and, yes, better shoes. The advancements in shoes have made a measurable impact, but there are lots of optimizations being worked on.

    Also population and access. In the time since the early 1900s a lot more humans exist, and more of them have the opportunity to attempt this record. Population in Africa exploded in that time and access improved significantly. If you're bloody quick and born in Birmingham (either of them) in 1900 you can probably find out about and get yourself a chance to attempt that world record, but if you're born in Kapsabet (in Kenya) in 1900 good luck, even in Nairobi I wouldn't bet on it.

  There’s info in one of the other threads about better carb intake too. But yeah at this point, “it’s the shoes, stupid” should defo be the main part of the conversation.

    I'm pretty sure that's an old trick based on some of the so-called cheese I've had on pizza

    Is that not what tomato paste and/or cheese is? Food glue? The other ingredients would fall off too easily otherwise. Or did the AI say we should be using PVA/cyanoacrylate/polyurethane glue or something?

Reviews say that they have very very good, but not record breaking energy return and shock absorption. But what they are is insanely light at sub 100g. https://runrepeat.com/adidas-adizero-adios-pro-evo-3 https://runrepeat.com/adidas-adizero-adios-pro-evo-3

  For a while it was all about getting the lightest shoes, because picking up heavy shoes slowed you down. Then the energy return (pebax foam, carbon plates/rods) became the main focus because the weight didn't matter as much when the shoe was literally springy. Surely this is now going to spark a race for the optimal balance between weight and energy return.

    I can absolutely imagine that the "correct" balance varies from one person to another, and yet that this is both measurable and also irrelevant for non-pro athletes. Like the number one endurance runner in the world will get a minute off their marathon time because a shoe manufacturer spent $1M making custom shoes for that athlete which don't even have a size they're just "For this one specific person, now" but then some guy on Reddit wants better shoes because he's sure his four hour marathon would have been "more like three" if he had those elite shoes instead of the $100 Nikes he wore...

The Nike Zoom Vaporfly's already had set this precedent years ago: https://www.nytimes.com/interactive/2018/07/18/upshot/nike-vaporfly-shoe-strava.html https://www.nytimes.com/interactive/2018/07/18/upshot/nike-v... The big improvement then was a carbon plate. Adidas (and others) followed suit. The subsequent improvements since then have been marginal but the margins are thin at that level. In this case the big advancement has been the weight of the shoe. EDIT: Also it's worth noting these shoes are $500 retail. Adidas will for sure get a boost in sales from this, but there's definitely competition in the $200~$300 marathon running shoe space that won't solely draw everyone to Adidas)

  Do these new Adidas shoes have anything major over the Vaporfly shoes? Maybe they are a bit lighter? I think the big story here may be the nutrition science to get these guys to absorb a lot of carbs during the run, more than the shoes.

Well if they’re sold in stores and next year everyone will have a pair, then it’s not going to be an unfair advantage, is it?

  There is a whole class of running shoes banned from various competitions. Essentially the argument given was too much advantage came from the shoes and they didn't want racing to be about shoe technology development.
