The Science Behind The World's Fastest Shoe - Cheddar Explains 

Not true at all. 4% over the course of a marathon has allowed more people to qualify for Boston and other races. If running in one of these events has been a long term goal and the shoes help, consider the game changed.

In fact it’s the opposite. The tech improves running efficiency (RE) which is worse in slower runners (with worse running form through the kinetic chain). Given that, these shoes have been shown to increase RE up to 8% in average runners.

@@ericpetersen8645 I genuinely want to read the study that you mentioned because from a logical standpoint, average runners do not possess the speed to fully activate the carbon plate. I would assume it performs best when a certain amount of force bends it (initial contact), causing it to rebound and the great rebounding force generated by the bent carbon plate should be even more effective in aiding lighter runners (the elites) in their midstance and swing phase (toe off), pushing them further forward than average runners. Also, average runners tend to land more on heel than the elites. Not that the elites don't land on their heels but when compared to average runners, the number of elites landing on fore and midfoot are higher than the average runners so it is a mix. The largest portion of the carbon plate is located at the toe area in most racing shoes, it is design with excellent running gait in mind (the elites'). If so, average runners with bad or not-as-good gait pretty much minimizes the intended purpose of the carbon plate since the carbon plate will not be activated fully or at all. The only reasons I can think of as in why these shoes make average runners faster are, the rocker design at the front of the shoe (which is present in many non-racing models and not mentioned in the video), the psychological effect, the light weight of the shoes and more foam which makes them softer thus reducing fatigue over longer distances, helping runners to maintain their speed for a longer time.

@@BugattianVeyronian For Heelstrikers, a carbon plate is in fact an additional resistance. Which is kind of obvious when you think about how a stiff sole is harder to walk on than a soft one. However, when you actually RUN, not jogg/walk, meaning landing on your forfoot, the plate will take some work off the calf muscle, achillis tendon and plantar fascia. You land on your forefoot and feel the stiff sole slowing down the heel on it's way to the ground - Which is naturally done by the calf muscle. Just when the foot is lifted again (assuming your pace is so fast that your heels barely/don't touch the ground), the carbon plate will straighten out again and release it's stored energy, propelling you up and forward. Go into a shop and just bounce in them like you were skipping a rope and you will feel that this actually works- you bounce more and use less energy and the impact felt in the foot is a lot softer as well, as the plate takes the beating.

The proper way to run is toe first and the heel barely touches the ground. That's why the spikes are only at the front of those shoes. Majority of runners run incorrectly. It's insane watching sprinters' legs in slow motion.

@@MrTUBEular10 that doesn’t work for distance runners, though. Too much toe running will be inefficient. Sprinters generally need power, not economy, so that works well for them

Know/love that feeling

You can just say "spikes". Any runner knows what you mean

Kingofrock37 That insane difference is only because you weren’t wearing spikes at all. The difference between even distance spikes and sprint spikes is marginal, the difference between different sprint spike models/brands is hardly enough to even be worth it… unless you want the placebo.

Like in basketball. Back in the day. They wear converse

The 1960 Olympic marathon winner was barefoot the whole race. His said the shoes offered didn't feel comfortable so he ran barefoot

@@waterproof4403Abebe Bikila-He was a rockstar, man!

@@johntejada5108 You're welcome, it's nice to see footwear science talked about more, I actually have a degree in Orthotics, external medical devices including footwear and various adaptations to it

The rounded shape is something that isn't that unique to Vapor Flys. Many running shoes have a similar roudning. The real secret sauce in the materials.

That is probably more relevant if you are a heel striker, but if you land mid or forefoot the rocking motion doesn't come into play as much. Looking at the form of many pro and elite runners they land primarily fore or mid foot.

I have nike pegasus that have raised toes and my toes get numbed during running bcz of that. Does it happen to anyone else?

@@evilbred974 Not when the Vaporflys first came out. It was the combination of the Carbon Plate for higher speeds, and the Foam for energy efficiency, as well as the heavily rounded back, and rocking forward design. Nowadays, years after 2016, most speed shoes have a heavily rounded back, and newer "super foams", and almost all brands have a shoe with a carbon plate, and some cheaper ones with a nylon plate. A plate in the shoe isn't unique to Vaporflys, Nike previous marathon shoes, which I still own, Have a nylon plate which you can feel helping you when you are running very fast. This is because it make the shoe stiff, and your calf doesn't have to work as hard pushing you forward. The airbag isn't new either, nike had the Air Zoom All-out, which were my first pair of good running shoes. Before the ZoomX foam, Adidas Boost was the king of foams.

For real, on Amazon now... $350, walking away from Amazon now, in my slow ass pleb shoes.

@@kurtlindner wow that's expensive

best shoe ive ever bought

These shoes only make sense if you really plan to run a half or a full marathon and actually wants to win. In other words, they are meant for races. If you just want a daily trainer, there're plenty other cheaper options that should help you well without providing too much assistance to the point of stunting the strength of your legs.

@@tayduatrinhcoi like which shoes?

lol ? who doesnt run ? its a basic in school

Wow!

Yep. The Asics Metaspeed Sky or Edge, New Balance RC Elite, Adidas Adizero Adios Pro, and the Puma Fast-R Nitro Elite are giving great competition lately with all these brands setting PBs with various athletes.

@@imjustariceguy any budget friendly shoes ?

@@User9681e For training? Well, there’s the Reebok Floatride Energy X which gives you a cheaper alternative to other carbon racers. I’ve never had one before, but many have attested to its incredible value.

He didn't cheat he is just smoking y'all butts.

U wear these shoes and have. Broken the record

They briefly mention it at 6:56

I was thinking the same thing, the stiff carbon fiber plate makes a big difference. To the point where the IAAF had to bad the use of two or more plates

@@johntejada5108 pretty cool that the producer checks the comments

@@johntejada5108 As someone who has put nearly 1,000 miles on these shoes (multiple pairs), I can tell you the carbon plate is absolutely key to this shoe's speed, hence why every other shoe company has emulated the design. You should also mention the awkward nature of walking in these shoes (especially if its your first pair), this shoe is not made for walking or even slower pace/recovery, it encourages you to run fast. I enjoy any video that spreads the word about Kipchoge! Overall, nice vid.

@@bobby2turnt Have any other shoe companies started using a pebax midsole since Nike introduced it?

…reallly? this is interesting

Yea I'm putting these as only running shoes category and sticking to barefoot like shoes for dailies

@@Selsmittenxo yeah I work with very flat and wide shoes as well. I think that’s smart.

Thanks for the feedback I regularly suffer from it

I got some shoes when I was 12 that had gel bubbles in the sole that you could see with a little window in the side. I was convinced that I couldn't be hurt by falls anymore. I kept jumping off higher and higher platforms to prove to friends that I had some kind of super powers because of the shoes.

To actual runners, it doesn’t make that big a difference. It is at best a matter of seconds per mile. Kipchoge, or any strong runner, could beat you over any distance in any shoe

@@kyanshlipak4258 oh I agree. These small differences are only noticeable when in the hands (or feet rather) of people running at the limit of human ability. I suck at running.

Any professional runner could beat any casual runner wearing flip flops. The shoes really don't make a difference in a macro sense. Yeah, they can shave seconds off your overall mile average, but these shoes aren't turning non-runners into world record breakers.

@@brandonb.5304 yeah I agree with you 100%. But in the case of all the sudden records, it’s the shoes.

@@codycast im positive that the benefits of carbon plated super shoes are actually more prevelant in more casual / slower runners as it just means the user doesnt waste as much energy

Look up Daniel Komen and Haile Gebrselassie world records. Also Bekeles 12:37 5k WR from 2004 has got to be the best run ever

How can a plate act as a spring??

Which Brooks model were you wearing if I may ask.

@@LuisFernando-yd3mx Brooks Hyperion Elite 2. The 3s are out now, but I'm probably going Nike for my next pair.

@@EtherBoo which shoe are you planning on buying next?

@@kwstaslungu1522 I'm very likely going with the Nike Airfly Next % (forgot the exact model, but not the Vaporfly as I read that supposed to be for shorter distances). I MIGHT go with the Altra version because that Toe Box is just luxury.

That will be majority placebo. The noticeable efficiencies in vapourflys are typically at the higher end of pace. I cant see how it would effect your zone 2 pace by an entire minute that’s just not possible.

@The Crazy Amateur Runner well someone can't be best until he competes

I think the greatest marathoner of all time is from the past. I think that runners from the past were definitely much more stronger in running than the runners today(stronger legs, bones, healthier diets, etc). And they used their feet to get around more than anything else. But we’ll never know since it was never documented.

Isn’t that a bad thing tho? Like doesn’t that feel cheaty to you?

Ukraine citizens really have it rough

Wow!

any knee pain with the alpha fly?

what shoe was that?

@@alohalani9743 it was a Brazilian shoes called Corre Vento - olympikus.

...and I bet you have knee, hip, and back pain to this day. Congratulations consumer. Modern shoes will never be better than your bare feet that nature designed.

@@glenwoodfore super based, and barefoot-pilled

Shows how utterly amazing it is! He also holds the marathon record at 2:04:58 run in a slow course (Boston).

Athletic Propulsion Labs tried this with a shoe that made you jump higher, but they got banned by the NBA. You can still find the shoes online tho.

Crossfit Pros someone is going to have the weight bounce back into the face eventually killing a person by either blunt force cracking the skull open or by blunt force causing enough damage. I know having tried to watch this stuff on TV and the pros were within inches of smashing there face in one of the coemptions. Also some of those Crossfit people are needing whole body synthetic joint fluid put back all joints in due to how demanding some of the Crossfit challenges are or were before they changed up the rules a bit to give time before rounds of events not just going back to back to back into events with no single break, they have rounds now.

Security cameras are usually enabled 24/7, and have limits to storage and data rate. If you record 4k60fps video on your phone, you will run out of space in less than an hour and will have to do something with that data, usually delete it. Thus, the cheapest way to keep them running for longer is to lower the video quality.

That's a great topic to investigate

Because many are older. And because they’re cheap. Most security cams used come in those NVR all-in-one packs and are like $25.

Cellphones typically use high tech processor chips. Meanwhile security cameras are usually processed using potatoes.

24h video hd is to much data to storage

We need more people like you

The alphafly prototype didn’t have 3 carbon plates

Agree the video wasnt structured .. you got the word chaotic !

Lets not forget the importance of pacers in that race

other brands have their own competitors now.

What are you talking about? This video is about the shoe! We already know what a difference technique makes!

@@Wonderkid44 What i mean is like having bad form running with the nikes make u even slower and more prone to injury than having a regular trainer. I meant to say that the video didn't explain how the runner runs impacts the performance of the shoe not just the shoe being amazing.

also drugs

You purchase vapourflys to do your callisthenics in? 🤣🤣. What a waste of money
