To all of you who think simply "banning carbon fiber" is the answer, let me explain how meaningless that would be.
Forget what you think carbon fiber is on it's own, try and think of what it's role is in these midsoles. It's primary role is allow a superlight, soft and resilient foam to actually be runnable. by giving it the requisite stiffness and reduction of torque, shearing etc.That's number 1. Then you can line up everything else like allowing maximum force transfer to the ground, reducing work in the metatarsal joints, increasing lever length of foot etc etc etc.
Well guess what, there are a number of materials that will fundamentally do this exact role instead of layered carbon fiber - hundreds of injected PA nylon materials that you can reinforce with all sorts of sh$t (glass fiber, graphite particles, carbon fiber chips etc etc) and they will be impossible to ban because all these things have been used in literally thousands of shoes over the course of history
And before all you engineering gurus point out the differences in stiffness between layered CF and a reinforced nylon - yes this is some - but nothing that can't be overcome with some simple geometry additions (like small I-beam ribs etc) - many things. The pure bending stiffness values of these plates aren't even close to the most important factor - in fact it's probably the least.
The point is, the issue isn't carbon fiber so get this out of your minds. The reason this will never go down is because the "secret" is the curvature of the plate and a soft resilient foam. Highly unlikely there is enough to grounds to ban either considering they have all been used before. So what will happen is the patchwork ban on stack heights and honestly, this isn't going to effect anything at all except stopping Nike layering up their cushioning technologies looking for micro increases in resiliency.
Bottom line, just get used to this. You can sit there and complain all you want but this is the future and we aren't going back to die-cut EVA midsoles, ever. Sorry Deek.
