It looks like another colorway of the Andre Agassi signature classic Nike Air Tech Challenge II is in the works. This design sports a full-suede upper, draped primarily in grey, with a lighter grey used for the graphics. To keep the sneaker from being completely neutral, the sole has been wrapped in bright orange, creating an interesting color combo. No word yet on when this colorway will hit stores, but stay tuned for an update in the near future.
