Non-Nike Athletes May Be F**ked - Nike WILL Release Alphaflys and they WILL BE LEGAL for 2020 Tokyo

Every midsole material is a "spring" in the general sense that it "returns" some of the athlete's expended energy. The airbag is a more ideal solution than even ZoomX foam because the airbag cannot be bottomed out in realistic conditions.

Yes, I know, that's why I mentioned hysteresis loss. That's the energy that isn't returned.

Only shaving razors take advantage of hysteresis ?

Not to mention that the airbags can be differentially pressurized, which can be beneficial on a track where you're only turning one way. The "density" of airbags can be varied with no weight penalty, while with foam, there's a weight penalty.

Hey Rojo, I would also focus on the notion that being made available to a small number of Nike's athletes/employees equates to being available to the general public at large. That is a mockery of the rule...

They aren't available to only a small number of athletes or employees. They will be available to anyone who is a member of Nike Run Club, which is free and available to literally anyone.

Yeah... tell me how you feel when you try to get a pair and they have run out from the get-go....

I have a bridge to sell you, interested?

So no, a 39.5mm/51.5mm shoe will not meet the max of 40mm. Both measurements need to be under 40mm. It could be that the foam rises up around the heel cup, making the stack height look taller than it really is.

+1

That's what I thought. Nike copying Hoka's design there.

U know nothing Jon Snow wrote:

The rules say 40mm is the limit for a size 42 (US men's 9) and that they can increase "marginally" as the shoe scales to larger sizes. In another article today discussing the new shoes, a Nike VP is quoted as saying the Alphafly is 39.5mm (for size 9) but that since Kipchoge wears a size 10.5, his legal shoes are 45mm.

.

I’m calling bs. Where is the quote? 39.5 for size 9 would mean something like 39.7 or 4o.2 for size 10.5 not 45 mm.

If this shoe really comes in at 39.5 and Kiochoges shoe was 39.5 the I’m thinking the whole thing was setup to ensure Nike’s shoe was legal. A lot more work needs to be done looking into this because when the rules were announced nearly everyone was under assumption that these rules were limiting the Alphafly and Nike. If instead they were greenlighting them as the gold standard that is different.

indeed, these regulations are reeling of financial interests.

Who knows, maybe Nike isn't just putting big money into research, development and big marketing alone...

reeling = reeking ;)

I think at this point it’s fairly obvious that Kipchoge wasn’t wearing the production model Alpha fly...stack height aside his were rumored to have more than 1 carbon plate.

If these are more akin to 6%, and are worn in the Olympic trials, Huddle, Sisson, Hall, Faubs, Ward and others might now miss out...

Well they are called NEXT% and not 6 or 7% so I would say it is a small upgrade.

There will be small releases of Vaporfly competitors from NB, saucony, and Asics this month to get their shoes legal for this summer, before the larger advertised releases in a few months.

Adidas is going to be okay. Skechers will continue to surprise.

But Brooks/Saucony/Just about everyone else needs to buy out OnCloud yesterday to stand a shred of a chance. Nike has tried everything for the past 50 years, and they're putting it all in these shoes. Nobody has patents that will allow them to do anything remotely close.

Trials are going to Nike and Hoka. If Hoka grabs OnCloud IP, Saucony and Brooks are a memory.

How is Adidas OK, but not Brooks or Saucony? At least Brooks and Saucony are releasing VF competitors this spring. Does Adidas have anything that comes close? The way I see it, Adidas has been caught flat-footed with its own technology (carbon plate, foam). Boost shoes don't even come close to VFs. I'd buy Reebok Floatride ahead of Boost at this point.

If you would follow leaks on the new Adidas shoes... One is officially releasing in the next week with teasers on official Adidasrunning IG and one was seen on the Houston marathon and on the track in Iten. They are quiet, they work on something until they make it the best they can.

Their shoe will have a 8% advantage, not 4-5% (not actually but I just want to say they try to make something as good and perfected as possible before releasing it)

And for people who complain about the technology ruining everything. Well it was almost the same with Boost when it came out. Sure it was heavy (and it still is - Adidas should have made it lighter or something) but the energy return was off the charts compared to other shoes.

Maybe I should buy some Nike stocks!

I think the bigger question is how are the determining what shoes are legal or not when they haven't defined a "marginally" higher stack height for larger sized shoes. After a race if a runner with larger sized shoes are taken and measured what are they doing with the stack height measurements? Is it up to the person measuring if they meet the "marginal" standard or are the measurements sent to WA for a ruling? Seems like it would be really messy especially when it comes to smaller races. It would seem that it shouldn't be too difficult to create a formula that would give you an exact stack height measurement limit for any given length of shoe.

No, the reason for sponsorship is for athletes to promote their shoe brand as the best. If these other brands are not the best then these athletes picked to back the wrong brand. They chose money over winning. That is on the athlete.

Anybody got a price prediction?

Man, Nike must have paid some nice overtime last night for some employees to post on the message boards all night shilling for them.
