http://www.adidas.com/us/content/mutombo Man the only other retired player with a shoe line is Jordan. Diamonds are forever and so is Mutombo!
This is just a re-release of the original shoe. Nike/Adidas/Reebok release shoes from retired players all the time; Iverson, Ewing, Penny, Shaq, Pippen just to name a few. That's just in bball; The Ken Griffey's were just re-released too.
As mentioned, those are releases of his obviously 90's shoes. There's better looking versions out there. Spoiler
He's not even the only retired player who shoe has re-released Charles Barkley Penny Hardaway Tracy McGrady Dominique Wilkins Shaq All have had shoes out.
Not to typecast or even deride his off-the-field humility and success, but if Olajuwon had half this guy's charisma he would have had a lot more stature, probably might have even taken Robinson's spot on the Dream Team.
uh... are we forgetting someone? shame, shame... http://dr34m.com/ pretty sure dream has some shoes out.
