It's interesting that the Alphafly feels easier but is only marginally faster over shorter distances. Again, it was designed for marathons where every bit of saved energy adds up to faster times. Probably not the shoe for running 5k or 10k, but I'll probably break down and buy a pair anyway lol!
True however even using them on hit training "sprints" they reduce stress on the body by a lot. Making it possible to at least add another session each week.
5 minutes for a 3 hour marathoner. It is more than I expected! Thank you for testing!
You can try different paces like 5 k, 10 k and marathon pace and se wich pace you get the best reward when you run in the alphaflies
Great idea, would be very interesting to test that!
Half for me, it takes some time to get used on em
I've been using STRYD power pod and testing out non carbon vs carbon shoes. I've been running about 8-10 seconds a km faster and using less power. That's a huge difference, especially for a marathon. Great video.
Ok cool to hear that's very interesting been wanting to try iut STRYD myself. Thanks! 😊
I think that’s a huge difference, just imagine how much training you would have to do to lower your heart rate by that much
I’ve never worn alphaflys, but I do have a pair of Clifton 8s and I love them. So the fact that you loved alphas so much more and the heart rate was lower just proves that alphas are amazing
The Alphafly makes a big difference to elite athletes and only over a certain minimum speed required to benefit from their energy return properties. If you are only an average athlete forget about it as it could be even harder to activate and make you rub slower not faster. Elite marathon runner on the other hand, they represent a huge advantage
Can't believe the difference. I just bought the 2nd Gen ones and from my first warm up the speed vs HR/PE was insane. I have immediately bought a second pair because I'm going to invest in running most of my training in them given sciatic issues and being four operations deep into my left knee.
What a beautiful color on the Nike Alphafly’s
Yeah I like the color as well they look fast 😀
Nice test, really impressive, especially on long runs, will that make the difference. But you're right more training would have the same effect, at least for the normal runners😉 For 300 bugs I get 3-4 of my normal running shoes.
The Topic of shoes is very interesting, do you have more than one pair for your normal runs, or do you have shoes for different runs for example forest or concrete. Please make a video about that😊
Greetings from Germany
Thanks! Yeah I hope that is the main takeaway from this for most people that you can make bigger improvements in spending time on training than spending a lot of money on shoes. Ok good suggestion will maybe make a video were I talk about that in the future!
I'm your a New Fan from the Philippines..
These Nike shoes are special even for a beginner like me I felt strange for walking then I ran 10k it gave me some extra energy to run fast all time 😂Hats off to Nike for creation.
These shoes will 100 percent prevent injury. I had a pain in my left knee and bought the vaporflys and the pain has disappeared since i started using them. Just got the alphaflys volt edition and they feel next level again. 💖
vaporfly or alphafly?
@@io-rj6sk for half marathon vaporfly and I would go alphafly for full marathon. Version 1 that is.
The colorway on those is awesome - we do not have those in the states. And I totally relate to that 'WOAH' moment you had when you first started running in them. First time trying the Vaporflys is etched in my mind - was completely blown away
Yeah they look pretty cool 😀 Ok cool to hear you experienced something similar, it was really a new and nice feeling to run in these!
Fr I went to the store and saw alpha fly’s irl On Display for the first time and decided to try it on for fun I was just doing high knees and such but I could almost feel myself bouncing I literally started smiling at my mom in amazement from this shoe lol
At 3.30 pace but your HR was not above 140 bpm. Damn! that's very impressed.
Haha thanks, but part of it is that I have a low max HR it's about 183.
I am super late to the game on the alphaflys. 1 because initially they were hard to get and 2 the price is ridiculous. Nike now has lots in stock and black Friday deals presented and opportunity I couldn’t resist. I like u was super skeptical think it was all marketing hype. My initial impression of the shoe is wow. I kept looking down at my clock and the thought “wow I shouldn’t be running this fast at only this amount of effort” kept running through my head. Other than the $, the only complaint I have is that the mid foot was unusually narrow. But after running, that stopped bothering me. Yes they are expensive. But if u can get them on sale, the hype is real.
Wow I bought an orange pair. But I really like the green. They look way cooler. I believe that the shoe kipchoge used had 2 or 3 carbon plates.
Ok yeah but I guess they are just as fast 😀 Yeah I've heard that as well so maybe that shoe was even faster than the final version.
Also to mention the leg saving aspect. For that alone they are worth the money. You only get one set of knees so pay the money to save them
Comparing the alpha flys vs the cliftons, is like comparing a porsche vs a ford fiesta.
Yeah you are probably right 😅
@@goranwinblad My 2 cents..any increase of efficiency and reduction of late race fatigue is worth the money if you are serious about your time you put into your training.
Great review and I love the different approach/perspective that you brought in this review. Thanks!
Thanks Chad I'm glad to hear you liked it 😊
'Motivation' is the key word here, with my running I only use Nike Invincibles as they are injury free, fun, decent price £120 and I do under 5k.
I run in army desert boots now because all my trainers would start to give me blisters on the toes after about 6 miles or so. I suppose it's to do with the shape of my feet. I get a lot of people asking about them and sometimes calling me a mad man. Very satisfying to overtake the same people on a race with all their fancy gear.
This breaks so many stereotypes that running equipment has so much to do with one being good at running. This was really helpful to know! Great video ~
Yeah the most important factor for your running performance is for sure not your gear. Thanks, glad you liked it!
At least, coming from you, sounds like an interesting and unbiased point of view. Thanks for sharing!
I'm glad you found it interesting, thanks for watching!
Thanks for the super comparison! Really fun video :)
Oooh the outro changed too :D Now we must "train smart" ;)
Glad you liked it 😁 haha yeah I'm testing it out should I keep it feels weird to not say "train hard" 😅
@@goranwinblad I think you should keep it and your regular subscribers will know why.
They are worth the money for sure. Lovely channel, but I must say that Kipchoge had a prototype of this shoe which is not allowed and not for sale on the market. Plus they are better for non elite runners vs. The Vaporfly Next %, as elites still prefer the lighter vaporfly.
Yeah you are right that was a prototype, ok interesting haven't tried the vaporfly but would love to compare them to the alphafly!
Lol 😂 you couldn’t resist it anymore. Those are awesome running shoes I love the color 🤩👌👍🏃😎
Sick colorway! I don’t think we have gotten that high visibility colorway yet. Jealous!
Yeah they look pretty cool! 😀
Great review well done. I was amazed and still am with my Saucony Endorphin Speeds. They really make you want to go quicker. I can only imagine what the Nike's must be like
Thanks! Ok cool yeah I've heard a lot of positive things about the Endorphin Speed, would be fun to test them against the Alphafly!
@@goranwinblad The speeds are sort of middle of the range. The Endorphin Pro are the super speed machines. Nearly £200 though so I haven't tried them.
Agreed. The Speed makes it easier to run a bit faster, a bit longer, with less fatigue afterwards. Great shoe!
Very educational video. Loving your videos. Keep your positivity going. 🙏🏽
Very interesting video. It would be interesting seeing you running on different distances and on different grounds and compare the shoe with a traditional running shoe. Also, how are the Alpha running uphill and downhill? You missed out on the status part. Having a Alpha and coming to my regular running workout group is a true blessing. It is like coming to work with the Iphone 1 once everyone else had a Blackberry. Once you see their faces you know you made the correct choice getting the Alpha.
Thanks Peter! Yeah that would be interesting, maybe in an upcoming video! Haha yeah the status part is maybe important for some but I only think that will last until the training start 😅 after that I guess it's more status to have old running shoes and run very fast 😀
Nice video. Just bought some new Brooks running shoes so this makes me feel a little better that those twice as expensive won’t change my pace that much. Keep up the good work!
Thanks! Yeah you are right I think you can enjoy a lot of fun running no matter the shoes you are wearing! 😊
very interesting that you use heart-rate as both dependent & contolled variables for the tests of comparing performance of shoes, it is easy to understand. i just click the sub button :-)
Thanks ok welcome to the channel! 😊
Have been running on my forefoot since reading born to run years back and always with Adidas boost.
The vapourflys look like they’re more beneficial for people that heel strike? Should I buy? 🤔
Im happy with them, I love your videos by the way
Just fyi, it's Hoka "Onay-Onay" (Hawaiinese)
Yeah I know it was supposed to be pronounced like that from the start but I think it's an expression from New Zeeland? But anyways from what I've heard the company has accepted hoka One One as pronouncing since it's how most people read it. But maybe I'm wrong?
no one cares
ONE ONE 1 1
You did not mention the difference in weight between the shoes. For example, believe it or not, I notice a big difference between a 6.5 ounce shoe and a 9 ounce shoe.
If some company could make a 3 ounce shoe, that would cut off some racing time seconds as well.
I’m surprised you’re saying that’s not a big difference. That was close to 4bpm/min difference. That is huge. That’s equivalent to running in 5 degrees cooler temperature.
Nice experiment. Good work!
I think the smile on your face told that it was worth getting the shoes. I am hoping to get a pair of Hoka Rocket X in the spring for some speed work, I think they will be a good addition to my shoe rotation and the price is a just a bit more than my other running shoes. It will be interesting to see how you get on outside on the AlphaFlys with that high stack height.
Haha yeah the feeling of the shoes was really cool to experience. Ok yeah those shoes looks good as well and yeah more reasonably priced. Yeah looking forwards to run more with them outdoors.
Oh and thanks for the video! Love and recommend this channel!
Thanks I'm glad to hear you like the channel 😁
Actually, saying this shoes are for elite only is not entirely true. I’m a lousy runner with a slow and moderate pace. I struggled running non-stop for 60 mins with other shoes, but with the Alphafly, I finished 60 mins run with relative ease. However, in order to run in this shoes with slow and moderate pace, you need to be more neutral in your foot strike. Over pronation or supination on these marsh mellow will result in a unstable platform. I’m lucky to be able to fit in Alphafly 2 as they are slightly wider. The arch is narrow but I’m do not experienced any blood blisters as others. I definitely hope that I can break into the shoe further.
Hi, nice review. I have the exact same color. Better than the Mango version.. To me they are faster than the Vaporfly on short distances but I cannot hold that tempo for a long run. So I prefer the Vaporfly’s for these. Strange thing is for both shoes I hardly experience any muscle strain the next day...
Hi! Thanks! Ok interesting to hear. Yeah I've heard a lot of people experiencing less muscle strain after running with these types of shoes, I guess it has something to do with that the soft midsole reduces the peak forces quite much.
@@goranwinblad thanks Goran- with narrow feet I have always worn Nike. Is there another brand you recommend with the same fit and sizing¿
The difference you are showing is huge over longer races. Also, the Nike is designed to not beat up the legs as much over distance. That is really a big factor towards the end of a long race. Training more is not a factor. You will still be faster on the Nike even if you are in better condition.
I'm dirt poor so the shoes I use for "racing" are decathlon's kalenji run one. Super light (180gr. for 43 size), hard midsole and are very very cheap. I don't think a casual runner would need anything more, even up to average recreational type of runners.
Nice video, tho
Yeah I have used Kalenji shoes in the past to and liked them, you are right you don't need an expensive pair of shoes to enjoy running training and racing! Thanks!
Can’t believe gym was empty...good video. And you are right you don’t need expensive running shoes to enjoy running.
It was early in the morning so that's why it was pretty empty, thanks 😊
@@goranwinblad perhaps a road test on them? 10km when not slippery
I'd imagine this shoe feeling like a mattress compared to my barefoot/minimalist running i do occasionally
Yeah they are for sure not a minimalist shoe 😅
Great vid! Appreciate the honest genuine feedback. Thanks.
Thanks I'm glad to hear you liked it 😊
I can just say m still at beginner to running after huge gap and i am still at 8mins per km. I got a long way to go.
That video i've waiting for
I really love this channel
Very nice contents!
Very nice video quality!
Thanks, I'm very glad yo hear you like the content 😊
Thanks for sharing with us👍 I’m really pleased with my Nike Tempo Next% 😁
Ok cool would love to try them out as well!
Great video, informative, thanks!
Glad you enjoyed it!
Watching your videos motivates me to run .
Thank you :)
That makes me happy to hear, good luck with your running!
thank you! this was wonderful!!
Thanks 😊
Do you have a video on how to pick your running shoes? If not, an idea!!!
No haven't made a video like that, but you are right that's a good idea, will maybe do a video like that in the future! 😊
I just bought one. I used to run around 3-5k daily a few years ago, but I never really had running shoes, as a result, my right knee is busted. I want to return to running again but wanted something that will protect my knees... I hope these shoes will do it.
Ok you are in for a lot of fun! Good luck with your running 😊
GL Gill and congratulations on getting back to the running lifestyle. I’m a devout Alphafly owner and have been running in them since they released to the public last year. At 240lbs, I can definitely confirm that these will help reduce the impact on your body. Just ease into it and exercise caution on uneven ground and sharp turns. Cheers 🍻
Cool video thanks very much! Just go on with this very interesting content!
I just bought a pair of Adidas Solar Boost 3, also not very cheap. But they feel great and I can‘t wait to test them! Greets from Tyrol/Austria
Thanks, I'm glad you liked it! Ok they look like good shoes too!
the energy return that alphafly gives is of different league ...
Seeing your reaction trying out the shoes is awesome! 💯 One question comes to my mind. Assuming you run 50km per week, and the lifespan of shoes is 1000km or less, it means you would have to change those shoes after less than 6 months? Or those shoes are mostly for races so you would never use them within such a short time frame?
Enjoyed this video Goran! Maybe do a fair comparison like adidas Adizero Adios Pro? And maybe on the roads this time (weather permitting)!
Thanks! Ok good suggestion would be interesting to do a comparison like that for sure!
I think you should do this workout, (6x2 km or any workout you like) with regular trainers on one day, then the same workout with the AlphaFlys on the next day. I think the heart rate data might be a little off, because if you start with the Alpha Flys on the first interval, then the regular shoes on the next interval, won’t your heart rate already start off higher with the regular shoes? I think if you do this experiment and found the average of all 6 intervals with the same shoe on one day, then the other shoe for all 6 on the next day, you’re fully rested and then can accurately find the heart rate average
Since I switch between each interval I think this comparison is more fair then doing it on different day since the heart rate can vary quite much on different days. I started with the Hokas on the first interval to don't give the Alphafly any advantages at least. Also the heart rate did not go up for each interval it stayed pretty much the same for the different shoes. I think it helped to do a long and quite tough warmup.
The color ways are pretty rad!!!
Yeah they look like a spaceship or something futuristic like that 😁
can you do Hoka one one carbon x vs Nike vaporfly next percent
Yeah maybe in the future if I can afford those shoes 😊
@@goranwinblad k
Energy return like this in a racing context is cheating in my book. It is basically a spring and if a spring is allowed, then you might as well go with a really big cartoonish one and have it done. Looks like good fun though
the amazon links in the description only bring me to the homepage, anyone has the same issue?
For me, two of the links are the same and the Next% link brings me to the page for buying the Hokas on Amazon
Hi! Thanks for letting me know the links should be working now, but it might depend on what country you are in. Try copying the link and pasting it in the browser instead of clicking on it for some weird reason that seams to work better for some people.
I have the hoka and love them.
Yeah I like them as well for training but I don't think they are the fastest.
Very nice quality vid - can clearly see you put a big effort in here👏🏻. Enjoyed it 👍🏻How would this shoe be for a 5km or 10km race or would you still rather prefer to use the more traditional racer type shoes for that ?
Thanks Rob, I'm glad to hear you enjoyed it! Well for me I would choose this one even for shorter distances like the 5k. But part of that is because I'm not used to running a lot on hard surfaces so I feel I need a more cushioned shoe to reduce injury risk and the Alphafly has plenty of cushioning while still being fast with great energy return.
@@goranwinblad 🇿🇦interesting 👍🏻appreciate the reply Goran.
Excellent testing 👌🏻
Thanks!
Awesome video, keep it up bro
Thanks Filbert!
In my opinion, Vaporfly next% is a better shoes not only it's lighter it's more comfortable and softer. I have 4 pairs of Vaporfly 4%, 6 pairs of Vaporfly next%, 2 pairs of Alphafly next% and one pair of Endorphin pro. Vaporfly next% is the best while Saucony endorphin pro is the worst.
Ok interesting to hear, would love to do a comparison between the Alphafly and Vaporfly!
Thank you for this review, very informative.
PS: you tend to lean your head on the right side, you might want to have that checked by a chiropractor.
Also, doing intervals back to back is not a valid way to check your HR variability. You were already in fatigue from the first set of intervals, and you went into the second interval with a higher HR and thus would impact the difference. Try this with 1 shoe on 1 week, then wait a whole week and try the other shoe. Then do this 4-5 x and compare the averages.
Well actually my heart rate stayed really consistent on all intervals with the Alphafly and all intervals with the Cliftons I think switching between each interval and doing longer and many intervals is the best way you can do a test like this (still not at all scientific mainly because it's just one person and heart rate is not the best measurement would be better to have a oxygen oxygen uptake test). These intervals was not super tough for me so I did not get more fatigue after each interval. I think comparing the heart rate from one week to another is really hard to get something out of at least for me my heart rate vary a lot from day to day depending on several different factors, for example over all stress both from training and work/life, temperature also effect it a lot so if the temperature in the gym would be some degrees higher or lower that would effect my heart rate more than the difference between the shoes. Also doing it over several weeks would mean that I had to live/train the exact same way for several weeks and spend a lot of time on a test I just do for fun and to get some indication. But thanks for your suggestion anyway!
There is something that is not accounted for in this test. The cushioning of the Alphafly will allow you to run harder longer. It will take less toll on the legs and feet in longer distances.
Yeah you are maybe right about this after interval sessions in these I feel less soreness in my legs.
Do you "jump" into them to use the push effect efficiently or do you keep on running as usual? Do you use only the front part of the shoe or the whole sole?
Thank you man!)
Excellent test! it would be cool if you tested other "super" shoes as well, like the Brooks Hyperion Elite 2, Adidas Adios Pro etc. If you can afford it :) Overpronators may struggle a bit with Alphafly. Maybe all super shoes are difficult dt. the softness of the mid-sole.
Thanks! Great suggestion, would be really cool to do a versus comparison between super shoes from different brand, will do it if I can afford it in the future 😊
Thanks for nice introduction. Would be intresting to see an in-depth explanation of how they actually works. I would also like to see barefoot VS vaporfly.
Ok, thanks for good suggestions!
Cool test
pretty enjoy your stile making videos!
Thanks! 😊
Very genuine and good review. Thanks for the same.
Thanks, I'm glad you liked it!
Tjena, grym video :) Hade varit riktigt intressant att se en video där du pratar om puls och hur den skiljer sig från löpare till löpare. Du har en imponerande låg puls exempelvis för att springa intervaller på 75% av maximal effekt, medan andra, som jag, hade legat i 170 - 180 vid samma träningseffekt. Jag ligger oftast i 150 - 160 i puls på mina lågintensivsrundor och tycker inte alls det är jobbigt (prattempo liksom) medan andra ligger nere på 120 - 130 i puls och kommer dem upp i 160 så är det högintensivt. Det är inte alls stor skillnad på min puls om jag ligger i ett 5:30 tempo eller 4:40 tempo kanske upp till 10 slag mer i 4:40 fart, men är såklart mer ansträngande. Vet inte vad jag vill komma med detta haha men undrar varför vissa har högre puls än andra även om dem skulle kunna prestera på samma nivå? :-)
Tack kul att du gillade videon! 😊 ja är stora individuella skillnader på var maxpulsen ligger, men verkar inte vara något som påverkar prestation finns världselitlöpare både med väldigt hög och låg maxpuls. Jag har lägre maxpuls än dom flesta i min ålder den ligger på 183. Tack för förslaget, kanske gör en video om puls framöver 😊
Great videos!
Thanks!
Very good!
Thanks!
Hey sorry to bother you. Really looking to buy these shoes. Cost isn’t an issue (only cause I live a simple life and I think I deserve to splurge on one or two things in life).
I run mostly as a supplement to JiuJitsu. They’re usually fasted consisting of 3 times a week with a variation of 3-9 miles, 2-3 miles with sprint intervals, or a mile for warm up with extended amounts of sprints before doing JiuJitsu/wrestling related drills in the garage.
Two out of the 3 days involves sprint training. Some days are 100 yards, others are up to 400 yards. Are these going to be ok for the sprint portion? If not, how so? Everyone says amazing things about these but admittedly they’re usually marathon runners. Wondering what are the cons for using it for sprints as well other than maybe more wear on the shoe. Thanks!
I will joiin you with this test as soon as our fitness centers open in Denmark.
Ok feel free to update me with the result would be interesting to see if you get similar results 😊
got these and completely overlooked the fact that they 100% aren’t suitable for any type of surface other then a track or asphalt,
I have a dirt track
would they hold up
Ok yeah they are made for asphalt use, so they will probably be worn out earlier if you use them a lot on the dirt.
@@goranwinblad how long did yours kast
Hey Goran, thanks for the cool video. Just curious... how was the traction? The slick outsole on both the VF and AF i think it makes them a one-trick pony (run on the road in dry conditions). Also did you swap the shoes after every interval or you just did two consecutive blocks of three with each shoe? And if so which one first? Just wondering if fatigue was also a factor in the difference between the two HR averages (if not wrong that was below the advertised 4%, although that's obviously been tested in a lab etc). Not a fan of this whole shoe trend tbh.
Hey Andrea! Thanks! I think the robber on the shoe should provide ok traction even on wet roads (I just tried them a bit on a wet road and felt the grip was fine). Yeah I switched between each interval rep to make the fatigue factor as little as possible and I started with the Hokas to at least not give the AF any advantages there. Yeah my test showed below 4% about 2,7% faster with the AF on the same HR but of course my test are quite limiting only testing on my self for example. Ok I'm also skeptical in some ways to this new running shoes making running more of a material sport. But I also see plenty of positive aspects, I see many people who like gear and different cool shoes makes them more motivated and in return makes them run more. Also more expensive products connected to running means more marketing money going to the shoe companies and when they advertise for shoes they also in a way advertise for running so I guess there are some good side effects as well.
I'm actually not a runner. But I have aspirations to be one
ooops, hit return. The marathon record still has not been broke. He didn't run in a sanction race, 2 he had pacers 3 he had a timer to follow to see what he was running and tell where he needs to be to make the record. So he didn't break the 2 hour record. He is still a great runner. I look forward to see him run in Tokyo, to see if he can break the 2 hour record.
Yes I now, I never said that he took a new world record when he ran under 2 hours. I only said that he became the first human ever to run under 2 hours on a marathon which is true.
the hoka shoes are quite good. You should compare the alphaflys with some worse shoes.
Yeah I like the Cliftons as well, yeah good idea would be interesting to compare them against a worse shoe.
You have great running form.
Thanks 😊
Nice "Hoka1 1"
Great video, Göran! How about giving them a go on a new 3k test at Melløs?
Takk Thomas! Ja kanskje blir det fremover 😀
@@goranwinblad I would not recommend using them on the track, spikes are superior to these when it comes to curves... these shoes were made for running in a straight line for long distances.
Please compare them with the Vaporfly
Good suggestion will maybe do that in the future if I have the budget to buy a pair of Vaporfly as well.
veldig kul test, må si du har lav puls i det tempoet - props for utmerket kondisjon :)
Takk Espen!
I got the mango one is really good shoes but I still think the next is way much faster
Ok they look cool as well! Ok interesting would love to compare these to the Vaporfly next % 2 that should come out soon.
You’re very handsome Goran, I also loved your review, it was very helpful ❤️
Did you count in the cardiac drift? Do you have training data available online? Also could you share the studies that claim better results with these Nikes? We know that Kipchoge's sub 2 hour run was a highly irregular "race" + he didn't really reach the claimed 4% shorter time by wearing them 😉
Yes that's why I alternated between the shoes, and started with the cliftons to at least not give the Alphafly advantage there. But yeah you are right as I said in the video a test on one person like this is not scientific just a fun way to get some indications for myself. There are some different studies on the vaporfly testing the running economy in different ways and comparing to different shoes. Just search for vaporfly on pub med and you will find some. All the data from the testing is available as a benefit for my Patreon supporters, link in description if you want to check it out.
@@goranwinblad good stuff 👍
Where do I buy these in Europe? Not amazon please
In Norway and Sweden you can buy them in Löplabbet, I don't now about other countries in Europe.
Will you consider trying them out against the saucony endorphin speed or pro?
Good suggestion, yeah that would be a very interesting comparison, will see if I have the budget for another expensive pair of shoes 😅
Hi. Göran! Do you normally run your long intervals as such a low HR? You ran 6*2km around 75% of max HR. I feel that I run at pretty moderate speeds at my long intervals, but around 10% higher percentage HR. Should I chill? :)
Hi! No I usually run with higher HR during my interval I didn't think it was going to be this low at that speed if it would have been a normal session I would have turned up the pace a little bit after the first interval but of course because of the testing I needed to stay on the same pace.
