The wait is finally over, Nike has just released the new Air Structure and Air Tech Challenge II. I know many have been highly anticipated either of the two models and both have just been released at Proper.

The two models are two of the hottest recent releases, the Air Structure is relatively new and this is the debut release of the Air Tech Challenge II. Both releases are a two huge steps for Nike, one being a new color-way for one of the hottest new retro lines and the debut line of the follow-up release to the first Air Tech Challenge model.
