Flight School: Nike Air Tech Challenge IV
Worn by none other than one of the greatest male tennis players of all time, the Nike Air Tech Challenge IV would have been popular even if Agassi never laced them up. First released in 1991, this shoe is just beautifully put together–from the numerous detailed panels to the different colored tie dye on each shoe. To this day, the Nike Air Tech Challenge IV is one of the most sought after pair of kicks Nike has ever produced. They were retro’d in 2000, but as we all know, nothing compares to the original. It’s safe to say the Nike Air Tech Challenge IV were the best in the Challenge series.
