I've recently become a Puma guy, though I was an adidas guy for the longest time. Makes sense, since both companies were formed by brothers.
I had the Superstars for a while in different colors:

Man, though I wish I could've gotten the Puma pony-hair franks:

Real pony hair! They started off at the price of like $200, but NM had them discounted to $75 and they all sold out. Damnit!
I also have the hitop Chucks. You Converse fans are really gonna drool about this, if you haven't already. I want a pair of these:

They're the original sneakers! Before Converse and Chucks! Expensive, too, though I'm not sure exactly how much.
