If the carbon spring was removed the shoe wouldn't have the same affect.
If springs don't matter then people wouldn't have a problem with Oscar Pistorious running in the Olympics.
The issue is essentially how big the spring is. A shoe is a small spring that compresses a few millimeters and makes you run faster by reducing the metabolic load on your muscles (if the spring compresses, your knee doesn’t have to bend as much). Lots of shoes increase running economy this way vs being barefoot. Cushioning is a spring.
The issue with Pistorius isn’t that he has springs, it’s that he has springs that have replaced half of his body, which compress a great deal. Tons of work that other athletes have to do with their muscles is being done passively. He’s also more efficient because he has so much less weight at the end of his legs, which is where weight matters the most. That’s why he shouldn’t run in the Olympics, not because he uses springs and other athletes don’t. (Particularly because sprint spikes in particular are extremely rigid.)
You have, however, accidentally stumbled on one reasonable way of regulating shoes: limit the stack height. Because every shoe is a spring (or “spring loaded” as you put it), just limit the size of the spring.
Anyway, the point stands: can you come up with a way of banning the Vaporfly (other than just naming it) that wouldn’t also ban track spikes?

mmm, I suspect you really know the answer already but playing devil's advocate let's have a look at this picture:-

Clue: It's the reason Vaporflys are essential f*cked after ~ 100 miles.

So when Bowerman was making all them adjustments to his team's running shoes he was cheating ??
Last time I checked Bowerman wasn't putting springs in shoes. It's one thing to improve traction and cushioning of a shoe. It's another to add equipment to shoes that litterally propels runners forward.
Corked bats aren't allowed in baseball, certain wet suits aren't allowed in swimming, a spring loaded shoe shouldn't be allowed in running.
And the 4% have been banned were ??

Stop calling it a spring. It’s not a spring. It’s a plate.
Is a shoe horn a spring? No it’s not, so I don’t call it one.
Stop calling a plate a spring. You narrative changing hobby jogging tool.
is that the same though? wrote:

So you wouldn't be opposed to someone winning in roller skates as long as the wheels were hidden? It's not just a shoe, it's a shoe with a spring in it.
So the 4% is the same as wearing roller skates to you?
I've never word the 4% and probably never will. I guess I just don't believe the hype. Has there been any actual studies done on the current available model that shows that they give an actual advantage? If so, which shoes were they compared against? Is everything else equal other than the carbon fibre plate (same weight, amount of cushion, same type of cushion material, stack height, drop, etc etc.).
I should say that I have big concerns about placebo effect. I think if someone drops down a lot of money on shoes that are suppose to make them fast, it will make them fast. So the study would also have to control for people not knowing which shoes they were wearing.
That study would be named Amy Cragg.

Awesome. So, what was your experience in them? Did you run a race, or just go for some runs in them? How far did you go? Some have said their legs felt more fresh at the end of their marathon. Did you experience this? I've heard some people complain about pressure in the arch (that would fade over time), but could be uncomfortable. Did that happen for you? And what are some of your stats (age, weight, typical paces) for comparison. I'm very interested in how big a difference they made for you. Thanks in advance!
Some dude probably banged OP's girlfriend while wearing the 4% and now he wants to cry about it.

Wrong!
Definition of a Spring:-
"An elastic contrivance or mechanical device, usually consisting of a strip or plate of steel (or a number of these) suitably shaped or adjusted, which, when compressed, bent, coiled, or otherwise forced out of its normal shape, possesses the property of returning to it.”
100% fits the definition of a spring. The only problem is your basic lack of understanding of what a spring mechanism actually is.

Is that all there is to your argument? You must write the make the best arguments/write the best essays in your college classes.

Nice find re the definition.
I guess though that's what Nike has going for it, i.e. the fact that most people would only understand a spring as a strip of coiled steel, so when they don't see that in the Vaporflys their comprehension of the issue breaks down.
Why stop at the 4%? Ban shoes and all apparel outright. Make everyone run barefoot and naked to remove any and all benefits shoes and clothing grant runners.
The 4% murdered Rupp's achilles and with it, the future of American marathon running... ban them now!
Caffeine is a well known performance enhancing drug. Doesn’t it bother you much more that people are allowed to use this drug and compete? Shoulsnt anyone who had a cup of coffee before a race (or otherwise ingested caffeine) deserve an asterisk beside their time?
Please tell me you don’t drink coffee?

Funny, when I google "spring definition" it comes up with this.
a resilient device, typically a helical metal coil, that can be pressed or pulled but returns to its former shape when released, used chiefly to exert constant tension or absorb movement.
So let's please start referring to foam in running shoes as a spring. When trying on your boosts, I want you to say "the spring in this feels good".
I'm excited to hear what you guys have to say about the new hokas coming out.
100% the Vaporflys should be banned. Just like the full body speed suits were banned in swimming. Was kipchoge wearing them in Berlin? That WR should have an * next to it. This is not a troll post.

Wtf?!! You do realize that definition is exactly the SAME as the one I gave? ? You do understand what "typically" means don't you?
The carbon fibre plate is the spring mechanism not the foam. Moran!
