Go to a marathon amd you won't see one pair of Asics or NBs.
Puma makes the deviate nitro which are excellent running shoes though.
At most marathons you'll see either Saucony, Nikes and a few Hoka
I don't know how you havent mentioned brooks.
Anyway a long with run clubs, and social media runs sponsored by celebrities and/or influencers. Running and everything running is the fad.
The amount of people currently wearing on cloud, brooks, hoka, Asics, NB. They used to be a brand where if you wore them and bumped into another runner they'd be like "you run?".
These fat, overweight, non athletic, dad bod, post partum, mfs ain't running.
