Year Introduced: 1990

More neon! The Air Tech Challenge III picked up where its predecessor left off, only more so. Rock and roll tennis was here to stay, and if competitors wanted to keep up with Andre Agassi, they were going to have to wear shades. Unlike predecessors like Stan Smith (or contemporaries like Pete Sampras) who were content to spend their entire career in the same sneaker, Agassi played in a new model each year - good for us.
