None of the top 10 use PEBAX and at least 3 don’t even use PEBA. The Adidas and Puma use TPE, which works better for some of us in lab efficiency tests. Asics MS+ is Nylon based.
They are sprayed onto a standard last (mold). It’s not a custom shoe.
The 3D aspect certainly would allow for that in the future…they’d have to scan your foot and 3D print a last, and then spray over the last. Not sure how much value a custom upper would be given the midsole down is limited to stock sizing.
With no tongue or heel tab and watching Paula and Kristian struggle to put them on, it’s werid they haven’t had any input on a more Tri specific model.
There’s approximately hundreds of pennies worth of profit in making a “tri specific” model.
They sell like week old pancakes.
While I agree that it would be a small production run, Asics do pretty well with their Noosa Tri shoe? So there could be a market for something.
It’s generally done well as a style piece, not as something particularly runnable.

I’ve had every Noosa model since probably 9th or 10th generation, but I mostly use them for walking. I like the colourful pattern and otherwise minimalistic design.
I only do occasional runs in them (when I pack light and don’t have other option), rarely more than 30-40min, because of the lacking cushioning.
