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.

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.

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.
The Nike Zoom Vaporfly's already had set this precedent years ago: 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.
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.
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.

If I wanted to know what an LLM thought (I don't) I would go ask an LLM.
One person sharing what an LLM thinks is probably better for the environment than each person asking...

AI told us we should add glue to pizza
In this economy, it may be sage advice.
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?
You should stop using 3.5
I'm pretty sure that's an old trick based on some of the so-called cheese I've had on pizza

Is what the AI told him incorrect?
