Negesa (2nd place and Adidas runner) ran Dubai in Nike Vaporfly Flyknits dyed red to (poorly) mask the Nike Logo

That's got to suck if you're adidas.

This was in the Dubai thread, and I thought it deserved its own thread.

Moran ! But I must admit I did it once with a pair of Nikes while running for Saucony !

Better title would be "2:09 Adidas sponsored runner Herpasa Negasa wears Vaporflys and runs a 4% PR of 2:03"

Not sure what you're getting at. It was a 4% PR, which is funny because it's the name of the shoe and assumed to be a marketing gimmick because elites obviously wouldn't improve 4% with the shoe.

How is this possible, I thought the Adidas boost midsoles literally stored energy in those TPU balls to fire it back into each running stride when the foot left the ground. The Adidas advert had those ball bearings bouncing off the boost foam multiple times to show the energy return compared with other midsoles. Surely that would work better than a carbon plate?!

I guess I was more suckered by the Adidas marketing campaign...

The benefit from the vaporflys isn't to do with the plate...

I've tried both. The difference in amazing ! The adidas shoe is soft, but it feels like the return is lost in (no better word for it) misdirection. The Nike shoe is laser focused on forward return. I've only done training runs in them to test, but the Nike shoe is close to 30secs per mile faster.

Was the link to the pic taken down? Can someone repost?

The difference is the super thick super soft foam with the embedded leaf spring. It's the combination that gives the advantage.

Looks like he shaved / rounded off the pointy heel too.

Really, it was closer to a 5% improvement.

Had this on in the background and was pretty easy to find at the end.

The shoes are Adidas.

I'm not so sure that the shoes were the major factor in his ability to suddenly drop 6 minutes from his marathon PR. It looks like he has been training at a high level for years. He has run 2:10 on three different occasions from 2013 to 2016 before improving to a 2:09 last year...then a 2:03.

Almost as if his performance was suddenly and recently "enhanced".

Ahhh. You misheard. Its the left foot only. Not when each foot left the ground. The right foot gets no energy return and actually makes you turn in circles. Great for track.
