I don't think it matters whos name is on (or off) the pro model shoe. Shoe Company X owns all the rights to the shoe, except the pros name. When said pro leaves the company, I think that it can be entierly at the discression of company X to continue producing the shoe. They'd have to take the name off of it, as they no longer have claim to that particuar intellectual property, but as for the phsyical shoe, they own the molds, and the material, so crank 'em out by the dozen!
On that note, let’s see some more MJ1s and 2s from Emerica.
