rumor has it world athletics may ban the vaporfly from competition by end of month: https://www.businessinsider.com/nike-vaporfly-shoe-ban-decision-2020-1
So get better and become sponsored by Nike. Or buy the shoe like everyone else.Quote:
Many runners sponsored by other shoe companies would like to see World Athletics issue rules about Nike Vaporflys. Sara Hall, an Asics-sponsored runner, told Outside Online last yearthat because of the shoes, "it's hard to really just celebrate performances at face value right now."
Quote:
The secret to Nike's technology is in the sole.
In addition to protecting our legs from the impact of striking the ground, running shoes store and release energy to propel us forward. The midsole acts like a spring, compressing when a runner lands, storing the energy from that foot strike, and expanding again to return that stored energy into the ground to push them forward.
Not all of that stored energy gets returned with each footfall, though some dissipates as heat. But the Vaporfly soles fuse together a foam layer and carbon-fiber plate in order to minimize that lost energy. This helps runners get the most forward push for each stride; in other words, they can run faster for the same energy expenditure.
A February 2019 study conducted independently of Nike found that the Vaporfly shoes improved an athlete's running economy by 4.2% compared to Adidas Adizero Adios 3 shoes.

I got a PR because of my new shoes seems kind of hollow. If it pays you, by all means, but for personal achievement do you want your athletic progress achieved by your pocketbook alone?

Soooo...are these worth it to buy just as race day shoes for a non-elite? Like will it shave a minute or two off a half for someone who runs at like a 7:30 pace? Or do they just feel amazing?
Not really that different from raceday wheel rentals for ironman races. People will spend what seems like crazy amounts of money to shave relatively small amounts of time off of their finish times. For those who get a BQ time in a marathon or a Kona slot in an ironman, it is probably worth it.htxag09 said:
My understanding, and the owners of the actual show can correct me if I'm wrong, is that it'll be more than an extra $120. These shoes aren't your standard shoes that are good for 400+ miles. You only wear them for races and maybe a couple races. So in reality it's an extra $250, you're still going to spend what you spend on training shoes, these are in addition.
But either way, in the grand scheme of things, people are paying coaches and spending a lot more in training than $250 to knock off 10 minutes.

As for the shoes, it's tough to stop technology. You have to grandfather some in, then draw the line somewhere. Racquetball racquets, golf balls, and club heads, baseball bats...all of this stuff CAN be made lighter, hit the ball harder, etc. Hard to see them being ruled illegal after the murderer got to wear pogo sticks in the Olympics.
Interesting. I had to have custom insoles made because of Plantar issues this past year and the guy that measured/made my insoles told me that most of the ones that you can find online are not all they are cracked up to be. Even the expensive ones.htxag09 said:
I've been noticing advertisements on social media for similar concept insoles. If they were to ban these shoes, would they have to check insoles also? And I assume a ban would keep other manufacturers from developing them, or would they continue to develop and the ban be lifted when everyone makes these and they are now "easily accessible/available".
I just feel like it's a slippery slope to go down.

How do I stay in my stride? How do I conserve energy? How do I go faster? These are the questions our elite runners ask. This is the shoe that answers. With a DNA ZERO midsole and carbon fiber plate in the Hyperion Elite. Or nitrogen-infused DNA FLASH in the Hyperion Tempo. Because it wasn't just our scientists, designers, and engineers who made the Hyperion it was the runners who demanded more.
Punctuation must have been the engineer's contribution.Quote:

We counted every pair at the Olympic Marathon Trials and found 94% of finishers wore shoes with carbon-fiber plates.
