After his retirement in 2006, world-renowned tennis player Andre Agassi teamed up with Nike to release exclusive colorways of his classic tennis shoe. The Air Tech Challenge 2 features a white leather upper with Photo Blue and Mid Navy overlays along the Swoosh, sidewall, and heel. The sneaker also sports a synthetic lace cage for support, neon orange details surrounding the partially encapsulated Air unit, and a padded collar for a snug fit.
