During the late 80s when Andre Agassi walked on to the court he threw conventional tennis style out the window. Agassi's non-traditional look included long hair, brightly colored outfits, and of course, matching sneakers. The Nike Air Tech Challenge II is considered a favorite among the models Agassi wore throughout his career. Released in 1989, the ATC II has a lightweight synthetic upper that withstands the unrelenting back-and-forth action on the court, visible Air-Sole unit for superior cushioning, and an external heel counter for optimal support and fit. But, what most people remember about this model is the iconic "Hot Lava" paint splatter detail. Truly an iconic model that helped redefine tennis court style.
