I was skeptical of these right up until the moment I ran in them for the first time today. Even pulling them out of the box and trying them on for the first time, I didn't like the laces, the wide flare at the top of the tongue, the flimsy insoles. I swapped in a Currex arch support insole and that made a big difference. I envisioned these as more of a daily trainer than a speed shoe, but I set a PB 10k in these without even realizing it until my run was over. I was absolutely flying, and my legs feel as fresh as can be. And from what I've read, the foam only gets better as you break them in. These are like those Chinese EV's that are better than ours for a fraction of the price. I'm really excited to see what else they can do - my initial impression is there's probably not much they can't. Believe the hype.
