That looks awesome!! Can't wait to get my hands on a pair.

High stack height of vaporfly and zoom fly you just get no "feel" of the ground. This will eliminate that, giving that proprioception back with the thinner midsole. can't wait.

When will you idiots understand that the thing that makes the vaporflys and the next % amazing isn’t the plate it’s the foam??? The plate just gives stability because the foam is so soft. No show company is going to make a comparable shoe until they change the foam, adidas is still using boost material which doesn’t cut it anymore.

And adidas owns Reebok who has a legit zoomX competitor in their foam. Why not steal it from the sister company

I guess if it was that simple, the Reeboks would be flying off the shelf and winning races, right?

If adidas copied the Vaporfly, then it wouldn't be an Adidas anymore. As mentioned above as well.. we know nothing about this new Light Strike foam Adidas is using. That shoe barely has any Boost in it. All people are paying attention to is whether or not it has a carbon plate in it.

How do you know it doesn't have more boost than what you see in the heel? Look at the new Adios 5: the midsole looks fairly similar and it has boost from heel ti forefoot, just surrounded by the Lightstrike material like a rim, probably for stability.

As for the plate in the Vaporfly, it isn't just for stability but to stop movement in the big toe and relieve the ankle from the resulting extra stress. The gains aren't just from the foam, the curvature of the plate is key.

(can not find another source, so do not know if legit). Plenty of Boost.

These shoes look like Nike Zoom Elite 9 with Boost.

To my eye there isn't that much Boost (small wedge in the heel), and I'd guess it's being used there to avoid the sinking sensation you get in the Zoom Fly, 4%s, and to a lesser degree the Next. Also, the wedge shape would seem to promote the falling-forward paradigm of the Nikes. The Boost on the bottom...I don't know. Lighter than rubber? More durable than Light Strike? Also, to my eye, the stack height looks close to the Next (a little less) and therefore fairly significant. Anyway, with only the Nikes really to consider in this sector, there's no telling yet what is the optimal stack height for a shoe of this nature. I'm intrigued.

If you look at the below photo from the article linked in YetAnotherHobbyJogger's posting you can see the Boost material appears to be used used from heal to toe some other material on the sides from the toe to the mid-foot.
