In 1992, the Air Revaderchi represented the latest innovation of Nike's ACG collection (All Conditions Gear). The cutting-edge, outdoor cross-training shoe was designed for mountain biking, trail-running, trekking and any other outdoor activity the adventurous athlete wanted to conquer. And now, it's back; everything from the neoprene Dynamic-Fit sleeve and collar to the multifunctional outsole, all in a bold Gym Red colorway with earth-tone details.
