Brand move: adidas to Ewing 

He made the Nike Terminator a college basketball classic, but shortly after leaving G-Town for the Big Apple he inked with adidas. When you're the most famous face in a city that never sleeps its only natural to try and market and run with it as much as possible—and Ewing decided to leave The Three Stripes to start his own brand. Maybe it's lost in the historical shuffle now, but at the time, a professional basketball player heading his own sneaker brand was a HUGE deal. And while the first Ewing Athletics go-round ended prematurely due to a variety of internal troubles, the hope is that the recent re-launch will last quite a bit longer.
