can someone explain how these shoes are imparting such an advantage?
to people who run in them: do you notice your form change at all? what mechanics/part of the stride feel easier or 'upgraded', if any?

The really interesting thing is that no one knows how they work. It's not even assured that the companies that designed them know how they work. They could have just tried a lot of different things and went with what did work, or their own theory of how they work might be wrong and they work in some totally different way.
I have a pair of Next%. They don't feel like any other shoe I've ever worn. You walk around in them and it just feels like a bunch of cushion, but at HM/marathon pace, they don't feel squishy. My stride is longer and I'm pushing off the end of my toes, but I don't know exactly what the mechanical difference is.
There are big differences between a carbon fiber layup and a "carbon infused" plate, not gthe least of which is price.
Yes, the plate specifications can be changed without the consumer's knowledge.
Yes, there is such a thing as a placebo effect.
Stiff plate saves energy wasted from bending big toe. Curved spoon shape of plate (patented) reduces ankle forces compared to a flat plate and creates a teeter totter effect, where as you roll onto the spoon shaped front part, that flips the back part up. Kind of like stepping on a rake flips the handle up, but your foot gets flipped up. adidas Adios Pro gets shape of the curve patent by using curved rods instead of curved plate

are you suggesting placebo effect could be responsible for the recent significant improvements across all road running world records..?
I read an article a while back (alex hutchinson maybe?) that said it was the combination of the foam, the weight of the shoe and the plate that makes the shoe so efficient.

The point is the plebian mid-packers don't necessarily get the same shoes (though they may have the same visual appearance) than those being worn by the peeps setting World Records.

Yep, thanks my guess too. Nike had some data shown at a conference several years ago showing running economy savings with no plate, straight plate, curved plate, and highly curved plate. Highly curved plate was the best.
But, as we can see from the Zoom Fly it’s not just the plate, it’s also the foam.
So thanks my guess too. The plate tunes the foam to maximum effect. Without the plate or the superfoam it’s just a regular shoe.
