The Adidas Adios Pro Evo 3 - https://news.adidas.com/running/adidas-unveils-its-first-sub...
adidas introduces the Adizero Adios Pro Evo 3 – the lightest and fastest Adizero shoe ever, weighing an average 97* grams.
The race-day shoe represents the culmination of three years of cutting-edge research. It is 30% lighter, delivers 11% greater forefoot energy return, and improves running economy by 1.6% compared to its predecessor - making it a record breaker before it’s even laced up.
The shoe will launch with a highly limited release, with ambitious runners able to sign up for the chance to get their hands on a pair from April 23. This will be followed by a wider release in the fall marathon season. The Adizero adios Pro Evo 3 will cost $500/€500.
For other marathon racing shoes, Google says:
The Nike Alphafly 3 is the lightest in the series, weighing approximately 7.0–7.7 oz (198–218g) for a men's size 9, and 6.1 oz (174g) for women's sizes.
The PUMA Deviate NITRO™ Elite 3 is exceptionally lightweight, typically weighing 194g (6.8 oz) for a men's size 8 (UK)
You can buy them in the UK soon, just £450 and I suspect they'll disintegrate quickly... https://www.adidas.co.uk/adizero-adios-pro-evo-3-shoes/KH767...
If anyone's interested, the shoe being purchasable by the general public is a condition of them being deemed legal for pros, after a crackdown on Supershoes a few years ago.
The other conditions as I recall are there is only allowed to be one carbon plate in them and a maximum stack height of 40mm.
It really is incredible that Nike kicked off this Supershoe arms race ten years ago and spent (presumably) an incredible amount on R&D, marketing and hype to try and complete the mission of being the first shoe to go Sub-2, and Adidas has pipped them at the last minute... twice in one race. Oh to be a fly on the wall at HQ today...
Though I assume they made a lot of that cash back in the interim selling these things to weekend warrior suckers like myself!
Most superfoam shoes actually last longer than older EVA-based foams:
> Improved durability: Supercritical foaming produces a more consistent cell structure in a midsole. This should translate to pressure and weight being more evenly distributed, which should lead to greater durability of the midsole. “We’ve done a lot of testing of what foams look like on a dynamic impactor fresh versus 300 or 500 miles later, and we see less degradation in those materials longer-term,” FitzPatrick says.
> At least in terms of the midsole’s life span, super foams may have done away with the conventional benchmark that running shoes last about 300 miles. “I think it’s a dated standard,” Caprara of Brooks says. “It’s an easy go-to to help simplify. But every foam is different, and it’s not just the foam—it’s how it’s constructed, the shoe’s geometry, the rubber underneath it. There are so many factors. If I were to tell you the Glycerin Max lasts 300 miles, that’s probably less accurate than it is accurate. It’s probably closer to 500.”

Much like the road bikes that cost as much as a sedan, unless you are competing on a world stage, these aren’t meant for you.
I’m sure someone will happily sell them to you if you enjoy wasting money.
You don't need to be competing on the world stage to enjoy some of the benefits of Alpha flys or those pumas. 500 for the new Adidas does seem a little silly though.

There’s a lot of people trying to get a 3 hour marathon or some other goal where chasing the marginal gains is worth the cost to them.
