Here’s a look at an unreleased Nike Air Tech Challenge colorway. They feature white, tweed, and university blue with a touch of true red. We’ve seen a some of the new and upcoming colorways for the Air Tech Challenge retro, and this color has gone unseen until now. We don’t know if this colorway will drop, but as of right now it remains unreleased. I can’t help but wonder what would Mr. Agassi have to say about this colorway. TSG will continue to keep you updated with the latest ATC retro news. Thanks to movementy for the pics!
