Nike is masterful at making its brand appeal to the very hip and the very lame.
Go to a kids soccer game, you'll see dads wearing Nikes. Go to a hollywood red carpet event, you'll see stars wearing Nikes. Different models of course, but nike has a shoe for everybody.
I wouldn't be surprised to find out Apple studied Nike's approach when they first made the s3 available for super cheap with a contract. Maintaining luxury status, and selling to everyone just seems impossible. Nike is one of the very few successes.
