The U.S. Open is a week away, and Nike is commemorating the annual tennis event with another special makeup of the Air Tech Challenge II. Set to release this Thursday, Aug. 21, the sneakers sport a patriotic look with metallic red, white, and blue in the upper and the letters "USA" embroidered on the heel counter. Look for this former Andre Agassi signature to hit shelves at Nike's six NikeLab store's, including New York's 21 Mercer St. location as well as Niketown New York and online at nike.com/nikelab.
