So I ran some 100% unbiased tests comparing the Alphafly with the Newest Hoka and brooks hyperion elite and found that the results show that the Alphafly is significantly better. My oxygen uptake was the same in the Hoka and brooks at Marathon pace as the Nike at 10K pace (which for me is 5:22 and 4:50 per mile)
Honestly I did expect the Nike to be the best but by this margin seems crazy. Question is, I am more of a runner these days and doing less triathlon, in the running world the vaporfly and presumably the alphafly is prolific on the start line of races. In many events it seems like at least half the people are wearing some version of this. My understanding is that his is not as much of the case in triathlon and Hoka, Saucony, Brooks, Asics etc… all have a bigger market share.
Will this change and more unsponsored triathletes drift towards Nike? and will any of the other brands catch up? It is cool now almost every brand has a vaporfly like shoe but they seem to be comparable to the 4% or Next percent and Nike is still a step ahead with the alphafly.
Also, if you are still racing in another brand or maybe even an old school shoe, what is your rational for this decision?
You can find all the details and results of my tests in this blog/video I posted: https://blog.runningcoach.me/…-racing-shoe-battle/
This experiment has zero scientific value as you know which shoes you are running with, your test protocol is worthless and you were the only test subject.
I can easily setup a similar experiment and demonstrate that for example the Adidas James Harden Vol. 4 basketball shoe outperforms all running shoes as running efficiency is easily to influence by playing with cadence, stride length, vertical oscillation etc.
Also your heart rate values (and oxygen uptake) are completely useless: the last interval obviously records the highest heart rate, irrespective of the shoe.
For this to be a little bit credible you need more test persons, go through a sequence of intervals with one pair of shoes and repeat it several times and do the same with all the shoes and make sure the test subject can’t see which shoe its wearing.
Nike has good marketing but their shoes are not magically fast.
