Yeah not to mention breathing carbonfiber dust is super toxic.

Since i heard that i knew that the carbon fiber won't last. xD
Those tests... Oh, man those tests. The scientific method was murdered.

Thats Nick Symonds, not some random youtube influencer...
Respectfully, your conclusion is wrong.
Hi, my name is Ethan I am an Aeronautical Engineer with a degree in Mechanical Engineering along with a Masters in Systems Engineering and Design. There is a mechanical advantage because of the carbon fiber structural piece running through the length of the shoe. The term spring comes in all types of forms. What we have here is a cantilever beam type of spring (similar to that of a diving board at a pool)(also known as beam stiffness or bending stiffness).
Bending stiffness. The bending stiffness ( ) is the resistance of a member against bending deformation. It is a function of the Young's modulus , the area moment of inertia of the beam cross-section about the axis of interest, length of the beam and beam boundary condition.
In other words if you flex the shoe while running or jumping it will want to return to its center (flat) orientation. It is doing this because the carbon fiber is acting as a beam. That return of it's flat orientation helps your toe's not have to apply as much force to result in the same work output. Now, if the carbon fiber was very very thin I would agree that it would not have an advantage....but your cross section view (cutting the shoe in half) showed us that the carbon fiber piece has some thickness to it. This results in material grains being stretched on the bottom half of the carbon fiber piece and material grains being compressed at the top half. This is what causes the spring effect. It's also important to note that all shoes have this to some extent with whatever material they are made out of. The difference is that most materials shoes are made out of do not have nearly the beam stiffness that carbon fiber has.
My final opinion is that I do not believe it should be banned because technology has always taken us to new heights (figuratively speaking), why stop now.

Hi Ethan, my name is Rogers and I'm a Mechanical Engineer with an emphasis on Mechanism Design Cooling/Thermal Systems Design, Metallurgy and Manufacturing Systems. I graduated summa cum laude from MIT. I also hold three Masters degrees from Stanford in Aerospace Engineering, electrical engineering and computer science with a multiverse focus on Plasma Control System Design, Propulsion System Design, Aerodynamics (Subsonic to Supersonic), Power Extraction System Design, and Artificial Intelligence Design. But none of that matters because at age 21 I got my Ph.D. in Nuclear engineering from Harvard and my thesis focused on plasma and nuclear physics and how dark matter influences friction ratios in propulsion systems and affects steering load outcomes under reduced gravity loads.
Anyway, my point is, Nick is correct and you are wrong.
Thank you! Didn’t have all the terms to say it but that carbon ‘recoil’ is clearly the first order effect.
@@barchetta575m your background is a little odd, no one needs that many masters to work in any industry....but that's not the point
You gave us a lot of your background without telling us the justification of why you think Nick is correct....not sure what they teach at MIT but when you are trying to prove a side of an argument you should provide facts and information supporting your argument...here I'll help you out, first you can answer the following questions in technical detail...
Are saying there is no bending stiffness in the carbon plate? If so, please explain.
When the shoe is elastically deformed why does is go back to its original shape if there is no bending stiffness?
Also, why do the carbon plate shoes require more force to elastically deform than other shoes?
Lastly, if it requires force to elastically bend the shoe, how does the shoe not, in return, provide force back to the object it is touching?

"You won't believe what's inside!!"
Foam and a carbon plate? Pretty sure that's in every ad for these shoes.
pawala i remember when youtube was good
The clickbait bro
😂😂🤣🤣🤣🤣 exacly what Nike said is in it wow
hey nick, I was a researcher in a biomechanics lab and I've worked extensively with carbon fiber on quite a few projects, maybe I can answer some questions regarding the nature of the foam and plate combination. When you put force through items stacked on top of each other (in series) the modulus (bendyness) is proportional to the parallel combination of the moduli of the layers (A*B/A+B). because the resultant modulus of the parallel combination will be much lower than the sum of the moduli of the underlying substrate, the carbon fiber needs to be very firm to act as what we call a detent spring whereby the plate is very rigid to account for the foam. I have some theories on the manufacturing techniques and methods for the foam that they may use to increase elastic rebound but I can't exactly test them and I'm not in a position to drop 250 like that. Anyway the plate does in fact deform elastically under load, and it's that resistance to deformation that results in the springynes you see. as far as if it should be cheating, I don't think so, it's just an advancement in materials to me.
Interesting post. I'm a mechanical engineer and most people don't understand that nearly every stiff material is performing elastically under a load it's just that we can't see it with the naked eye unless it's in the form of a something like a spring. If you tried to compress a car spring with a your bare hands you might incorrectly conclude it isn't working as a spring! In fact you aren't putting enough load on it to see any deformation. When you run you are putting up to 3 times your bodyweight through that shoe. That's a sizable load, and you are going to struggle to replicate that with just your hands by trying to bend a carbon fibre sole plate.

Lmao.... Nurse, scalpel please.
my ap stats teacher is rolling in his grave over these tests
eleanor mancini just as I was saying: How do we know it’s not about you already being warmed up by the time you put on the Next%? It’d also help if he repeated the experiment now the other way around: Starting with the Next% and finishing with the Clifton? And also maybe repeat the experiment several times?
Yeah this was a shit show. Not to mention his vertical form isn’t perfect, and that test is famously cheatable
Anyone that has even heard the word “design” come after “experimental” at a college bar knows that this is bullshit.
I love how we are watching him destroy a pair of shoes for which most of us would die for.

Doesnt want the carbon fiber damaged, saws it in half.
There's literally no way to prove that you used more energy when putting the shoes on because your brain wanted them to be better
SuperMario Logan he’s right it’s called the placebo effect
Almost as if no one has heard of a blind study...
Tony in all honesty I think it’s just a light hearted experiment that isnt actually meant to take data from, it’s just to enjoy
It should be an pressure sensor in the floor and an blind test.
Film it with 3 slow motion cam on the 3 axis, put it on video software to compare accelerations on the body or the body members.

WHAT NICK SYMMONDS LOVED MY COMMENT!!!!
Thanks for the in depth analysis
All shoes have a mechanical advantage. That's why we wear them.
Fuck Nike they just want money so stupid idiots like this guy will spent $250 on fucking shoes.
No they don't, and that is absolutely not why we wear shoes. Protection, fashion and culture is why we wear shoes.
@@tc59932 Protection is a mechanical advantage.
@@KlaasBaas I don't think you know what "mechanical advantage" means. BTW, I'm a mechanical engineer so I do know what it means.
@@KlaasBaas Google the definition of "mechanical advantage"
I think the biggest advantage for your test was that you were going from a 9.4 ounce shoes to a 6.4 ounce shoe that has the same amount of cushion. Also, I think Nike's foam is the main advantage with the carbon plate creating support.
That was painful to watch, but really cool! Thanks for this!
subbed just for the excellent content oh and because Nick is awesome!
You just got yourself a subscriber. Been watching couple of your videos and good job
I feel like the difference in the jumps could've been chalked up to you getting used to the actual motions of the jump you were doing.
Regardless, thanks for dropping 250 so we could see the autopsy!
Possibly! Interesting that both tests went in favor of the Vaporflys though
@@nicksymmonds You kept getting better as you did more jumps it was most likely that.
i think so too, had he started with the Vaporflys and finished with the Clifton's, it would have probably ended up differently.
Look at the step up to the jump in each shot, each jump has a larger step for that counter movement. Like look at that step in the first vs last jumps hardly comparable. To test up and down he probably should have done a hard run up for each or none at all to test both raw and reactive strength for the spring of the shoe. The vast difference in step up changes too drastically.
@@nicksymmonds you pretty much increased height every jump...i bet if you would have continued in the the cliftons it would have contninued to go up
imagine returning those shoes
Educational. No BS vlog! I adore you!
I subscribed to your channel because of this video. Finally a Quality review and completely unbiased. Nice one!!
From what I've gathered, the zoomx foam is what gives the bounciness, and the carbon fiber plate does the same thing that a spike plate does for a track spike. The stiffness of the plate reduces energy costs.
I don't think that is true. Carbon fibre is a very springy material because of it's incredible stiffness to weight ratio. Just take Oscar Pistorius as an example.
Nick: I'm gonna be careful with this carbon plate.
Also nick: sawing off the shoe.
anymore that that there are nothing left.... using table saw many be better... next time....
LOOOOOORD
Coulda just done the sawing from the start and not went through all the bs
Keep it up Nick, keep it up!!
Love the effects. - so cool.

Awesome video. For a 1-1 test between shoes, it would be best to do each test in reverse, so with the NIke shoe being tested first, and then the Hoka Clifton just to have a side-by-side comparison of the results since your body does get a little bit of a chance to warm-up between the first test of the shoes and the second test with the second pair of shoes. Thanks, Nick!
Great review
yo i love it when you fast forward it shows that ppl can glitch too
A tear almost fell whilst watching this
It was really hard to cut those beautiful shoes open :(
It’s not even here in the Philippines yet. Huhuhu. Send me one and I’ll give them TLC (Tender Loving Care) 😂
4:41 dang that's a pretty fast heartbeat
Thanks so much for info n investigative report for vaporfly Nike Sneakers very impressive!
Great analysis
My heart sank to the bottom of my stomach from watching this lol
When you run slow like me it won’t matter what shoe lol.
I hear you lol. I’m in the same boat. But I’m searching for the most comfortable one so my knees don’t die haha
I also run (and walk) slow.
cool video Nick....thanks!!!
great video, Nick.
It would be interesting to see Stryd power meter data. Especially leg spring and form power
Nick, I thought when you busted open the shoes some RunGum was going to come out-then I’d really believe the shoes were performance enhancing!
ha!!! That does sound like something I would do lol
Loe your videos. Great quility and production and informative.
Great information. Super cool idea to cut the shoe open. Loved that!
Who else learned what aglets were from watching Phineas and Ferb
🙋♂️
Hats off to Nike, as he is still wearing his RunGum hat. 😆
Love this video!
Good Commentary. Very informative Nice.
I'm here just to make sure there is actually a carbon plate as advertised. Thanks man!
Would Alberto Salazar recommend this for someone not on illegal PED’s?
The carbon fiber acts like a built-in mini-pole vault pole in every step. It acts as a leaf spring, storing energy from compression in the heel and midfoot, bending, then it straightens back out and adds push off from the ball and toe. That is also how those VKTRY carbon fiber inserts work.
Oh mann.. Damm.. Your every video put smile on my face😂😂.thanks
Great video! Even if you didn't find anything fishy, this shoe helped break so many records easily. It helped you run and jump better. I don't know if you can say it is still a legal shoe.
You literally "*Took Flight*" right there lmao
I love this very unconventional review!!! BTW, congrats on your time in the marathon, I am trying to be under the 4 hours but it's not an easy task!
Thanks for this!!!!!
As interesting as it was to watch you cut this shoe apart. I am having an extremely hard time trying to find these shoes to actually run in for retail price. People want double the retail price and I cannot pay that 🙃
Eluid Kipchoge’s shope had an air poket. The pacers ran in the standard version.
@Pablo How do you know? Thanks
@@benpiriz4386 Eliud ran in a prototype shoe with air pockets. Rumors say that the shoe, Alpha Fly as it is called, will be available for the Tokyo Olympics.
@@benpiriz4386 If you Google there are some articles on it, and the printout what @NickSymmonds show in the video about "the patent" is about that Alpha Fly: you can pause it and see that in Alpha Fly there are two carbon layers sandwitched in the front of the shoe. Nike has multiple patents though. I'm in the first half of the video, but what Nick will find won't match the newest shoe's structure.
@@audunnystadkvitvr6713 I can´t say anything about the name, but i´m a customer in the same running store for about 4-5 years and friends with the owner. He told me, that he has seen the new shoes from Nike and that they will indeed come out to the 2020 Olympics, maybe even in an special Olympics style, although the "special style" was shown only as a concept to him, so don´t quote me on that :D
Great video Nick! I cut out the Nike Air Max rear air pocket back in the early 90s, and cut a recess for them in my Brooks basketball trainers, haha. Did the same as you and got the scalpel out and got cutting away. Was fascinating. Plus I played basketball in one-of-a-kind trainers!
Great Video!
Wow - there's literally nothing in the construction of these shoes. A few dollars worth of foam, synthetics and an inexpensive plate of carbon fibre. Regarding the plate/spring effect, it's probably due to the composite behaviour of the material. the carbon would be good at spreading the load into the foam, so you get to use more of the foam across the sole as a spring. As well as compressing the foam under it, the shearing forces as the foam is squeezed out the sides would also be available as rebound. Neat design, excellent marketing, fantastic profits.
Darren Steven yea seems cheap
So, you're saying they shouldn't be banned and all the people complaining should shut up?
That “rigid” plate of carbon IS a spring. With each step the weight of your body flexes the plate inside the sole. The energy stored up in the bent plate releases into your legs as it unbends, instead of mostly being absorbed by the ground, helping propel the body forward.
Exactly. They are classic leaf springs!
Very good video.
Keep going.
Great info
you could do a p-test to see if theres a significant difference
Could the difference in bpm be due to the fact that the first mile functioned as a warm up for you? Just like in a workout.. the 2nd set is often easier than the 1st.
Not really, I changed to a carbon fiber shoes and indeed my bpm was lower for the same pace
I like that you made the fast forward so fast it looks like your running backwards
Hey Nick i’ve been binge watching all of your videos! I’m no athlete but I do love the sport so I really enjoy watching people run and train and all that stuff. My favorite athlete is definitely Sydney Mclaughlin and i’m from the Bahamas so I also love my very own people Shaunae Miller and Steven Gardiner!
It would be cool to see a picture of just the carbon fiber plate without the foam around it!
nick: "roadmap"
Me: "does are the alphafly not the next%'s lol!"
Thank you @Nick Symmonds this video help me to add my data to make another design of the shoes. Cheers.
So cool you’re working at Nike store and in walks Matt Brody!!!!! Two gold medals!!!
This is a snuff film, I'm so traumatised 😭💔
"I don't want to ruin the carbon fiber plate"... whilst totally annihilating the entrire shoe LOL.
Wonderful awesome fantastic marvelous video good information well done keep it up
Great video. Many people learned from this. Thank you for educating us. I won't wear even a Nike t-shirt though!
Glad you enjoyed the video!!
I am sure somebody could use your method and “prove” exactly the opposite. You did prove that Nike has a better marketing organization.
That isn’t the patent for the Vapor Fly NEXT% shoes. That is for the Alpha Fly shoes that aren’t publicly available.
This whole video was so weird 😂
id watch ads like these every day xD
Nice video man!! I wondered what hocus pocus they had under the hood. I agree, no mechanical advantage there, just a well made pair of trainers :)
the shoe patent you downloaded was for the alphafly unreleased shoe use in 1:59 challenge. Those shoes have the air pockets. you took apart the next% which where release last year.
Cjspyker I had to check the comments to make sure somebody else noticed.
tjs1189 same here ahaha
Same lol
Same haha
You can see the difference in the shoe on the picture from vienna ;) It's a complete different sole construction.
11:27 My man forgot he was an Olympian haha
the alphafly has a nike air zoom unit in the fore foot area. zoom units have a very good response timing which is why they’re used a lot in basketball shoes
Love the personality and realization that this is FUN, not some scientific proof... Do you remember fun? Unbelievable the amount of haters and negative people in the world. They need to go find something they agree with and comment on that.
