Even though adidas already released what some readers consider “The Holy Grail of the [shoe] game”, they continue to push their ZX runners beyond the spectacular aZx Project.  Here are two new pairs of ZX600s.  The brown pair looks like Donatello — you get a suede upper with green leather stripes and purple accents.  The other pair is a cool grey with icy blue.  One’s a fighter, the other’s chill.  Find shots of each after the jump, then look to cop em in January.
