Released in April 2019, the Nike: On Air collection gave six contest entrants from around the globe a chance to develop an Air Max shoe influenced by their hometowns. Joining forces with Nike designers, Cash Ru created the Air Max 97 'On Air: Shanghai Kaleidoscope' sneaker. Gazing into the distance for inspiration, Ru's blue synthetic translucent upper is accented with white multi-layered heel tabs, emulating floating clouds that stretch across the Shanghai sky.
