Anything other than traditional plastic and TPU materials should be banned!
Carbon fibre plates a fu**ing springs and should be treated as such. Truely disappointed in the iaaf. First they get rid of the 5000m and then they don’t have the balls to do what’s right and ban these spring shoes! The iaaf is super corrupt right now and should be assessed! We as a people need to get Seb Co and his minions and board kicked out!!! Ahhh stupid Nike paying their way through.
NIKE VAPORFLY NEXT% BAN!

To sum things up the shoes are awesome but provide nothing near the benefit that people on this board say they do. The mad people wanting them banned are people who are poor and just don’t have the money to spend on nice shoes. Idiots claiming u will run 25-35 mins faster in a marathon in them need help.

Please post a link to just one example of someone making this claim on any of the dozens upon dozens threads this site has had on this topic. Thank you. -
What's the issue?
Kipchoge ran slower in London than in Berlin.
There was a time when London had the WR and Berlin did not.
Wake up sheep.
It's not the shoes.
It's the GOAT Marathon runner. -
Callum Hawkins is a New Balance athlete...

Foam can be springy as well. Other shoes have rigid components. Anyone acting like there is a hard, obvious line to draw -- well, they just don't get it.

I own a pair of the first 4%’s and the Flyknit version. They definitely propel you forward from experience and make running feel much easier; hence the 5% improvement in RUNNING ECONOMY! Look up what running economy is please people.
The plate needs to be banned like other shoes have been prohibited with similar tech. The real benefit comes for the elite athletes. 4% improvement in running economy is huge at the elite level.
Generally the other athletes drop off the Vaporflys wearers very quickly. Look at this new runner out of know where that just eclipsed Bekeles Marathon PB! -
Poverty + High mileage at early age + altitude + lightly regulated testing regime + great training + state of the art shoes = better than any US runner ever

Kipchoge ran slower in London than in Berlin. So? Yes Kipchoge is the best. He’d win without the shoes if everyone else couldn’t wear them too! But the times wouldn’t be of such a HUGE improvement sorry! He’s a great runner and it’s nice to think that ‘no human is limited’ BUT THEY ARE he was never a Geb or Bekele he was close! Hence why he’s above the rest of the fields.
There was a time when London had the WR and Berlin did not. So we all know Berlin is faster and now no names are running those times on a slower course and they all have these spring shoes in common? Hmmm amazing coincidence!
Wake up sheep. I think you’re Nike’s and a corrupt iaaf’s sheep. You’re the majority that has a blind fold on!
It's not the shoes. It’s the plate!

Yes he is so? It doesn’t make him a god, Bekele had more talent, he just got injured.

I think a fair standard would be to say that a shoe is illegal if it is more efficient than running barefoot. Maybe allow 1-2% of leeway just to make things simple. Barefoot running is pretty efficient, so most current shoes would still be allowed.
This would be impossible to implement. You would never know if a shoe passes until after it was produced and you got a bunch of lab testing done, and even then, the numbers would vary widely depending on the protocol used.
In any event, all racing shoes are more efficient than running barefoot. It's just that the VF is the best of the bunch.
I feel like it’d be doable, and definitely better than banning a specific technology. The problem is that if you ban something specific like carbon springs, Nike will just figure out how to make a 5% shoe with only foam.
Companies already make prototypes of every shoe, so it wouldn’t add that much cost. It’s not like they would have to build a billion dollar assembly line to find out there shoe fails. They could simply run a standardized test with an identical preproduction model.
Testing to make sure a shoe qualifies seems pretty straightforward. Get 15 elite/sub elite runners and have them run a few miles barefoot and a few miles in a new shoe. Measure and compare their oxygen consumption. If the new shoe is “too efficient,” it is banned from elite competition. Hobbyjoggers, the real market for these shoes, could still use them.
Also, I’m not convinced that racing flats are more efficient than barefoot. I couldn’t find any research on flats specifically, but comparisons with regular shoes show that barefoot wins. Obviously flats will be better than trainers, but still: the goal of traditional flats was to be as similar to barefoot as possible, so I don’t see how they could be better. Traditional 5k/10k flats are basically a thin sheet of foam glued to an upper; there’s not really any room to improve efficiency.
Either way, you could tweak the rule to allow current shoes. For example, give 3-4% of leeway over barefoot. Or, if you really want, you could base the efficiency comparison off of a standardized traditional trainer rather than barefoot. -

+1 great idea
Yeah this isn’t a bad idea. Setting up regulations that a shoe can only enhance performance so much. Then the can make them cushioned, leg protecting, responsive and whatever but they have to only improve economy by a maximum of say 5% to a barefoot elite runner average.
Remember that that 4% statistic is how much better they are then the Nike streak. -

Yes that’s true it’s thousands of years of Evolution that have made the East Africans of Rift Valley the best not PED. Jealous idiot westerners haha even though I am one! -
Good question

Maybe we should ban the vaporfly, but then what, what about the next ?

Well a lot of us are completely fine with Nike and anyone else making a shoe that is efficient with only using foam. In fact the Reebok run fast pro uses the exact same foam without carbon fiber and I would encourage people to use that shoe. The problem comes when you have a hard elastic material like carbon fiber and configure it in a way to produce a propulsion effect. There are only so many configurations you can come up with to create this effect but as Oscar Pistorius has shown the propulsion effect can create a huge advantage.
I fully believe that the 4% and the other carbon fiber propulsion type shoes work well. But whether or not they work shouldn't be the focus or concern. The focus should be around creating standards around what type of footwear you can use so that moving forward everyone is on the same page. If you create standards that all shoes have to follow to then this isn't a problem anymore and there is a clear limit to the advantage a shoe can give you. -

tarckstar, you seem to miss the entire point of what I said – EK ran 2:03:05 in London in 2016. And he did it without VF4%. Yesterday he ran 2:02:37 which is what – 28 seconds faster. So less than 0.7 sec per km. In almost perfect conditions (relatively low temps, almost no wind and low humidity). You see that it is only Eliud who is producing insane times. Still the second best time after EK was drafting behing him for entire race and barely got under 2:03.
If we ban VF4%, then I would say we should ban all the shoes for good. Since all shoes provide some benefit of cushioning and protection. Let's just go barefoot like good guy Abebe did in his first marathon win.

It's not difficult to get your head around this.
Nike had the carbon fiber plate in shoes before the 4% with the newer foam came out - Rupp had the plate in his shoes in the trials in 2016. I have zero doubt Kipchoge's shoes had it that year, too. You can go on and on about how it's the foam, and not the plate making the difference, go ahead.
It's the plate. Put on Pegasus Turbo and then put on Zoom Fly Flyknit. Turbo does very good job cushioning but the bounce is very barely there. ZF is ready to go like a rocket off your foot. Cushioning plus the plate is the 4%. Nike wants to lie to us about the benefits of the plate because they know it's cheating but it sells like crazy.
I think a better comparison would be the Zoom Fly FK and the 4%, both have the same plate, same upper, different foam. THEN tell us which one is faster. Obviously the 4% because of the ZoomX foam!
In regards to the "There's a spring in the shoe!!" Why doesn't anyone ever reference these bad boys. THAT is a spring!

Give every single elite runner in the race the same Nike shoes and the results would be exactly the same.
