Fun fact, the Air in Air Jordan was originally because they had air bladder insoles. I’m not sure they use that tech today but I remember pumping up my Nikes when I was a kid with a little basketball on the tongue.
Wow, I had totally forgotten about that! You're right, that's exactly how it worked -- if you had those you were basically the coolest kid in your elementary school, at least.
Reebok Pumps had the basketball on the tongue.
Nike experimented with inflation methods on the collar, IIRC using external pumps.
