The Nike Air Tech Challenge 3 originally released in 1990 as a signature model of tennis superstar Andre Agassi. This retro release of the OG "Voltage Purple" colorway hit shelves back in 2015. A white leather and mesh upper is accented with a jagged purple overlay, black Swoosh, and neoprene heel. Purple also colors the front of the outsole, and Nike Air branding on the tongue. Minimal orange hits can be seen on the eyelets and tennis ball logo on each heel. This pair also features an Air unit in the heel for additional cushioning.
