I suppose a good marketer could spin it. "My name may be Nike, but you'll only ever see these feet in Asics!"

Someone may want to "steal them away" from their namesake brand too for the same reason. "They're names after Nikes, but still won't even wear them for money!"

Advertising is weird. I'm sure if one was a star and companies saw a way to exploit that, both parties would be able to work something out.
