Taking design cues from classic, ‘90s Nike Air Max icons, the Nike Air Max 270 Flyknit sneaker gets an ultra-sleek update in the ‘Pure Platinum’ model. Released in February 2019, this iteration swaps out the synthetic upper for a Flyknit construction with a sock-like ankle collar. Swoosh branding adorns the toe box, while a white midsole gives way to an icy, 270-degree Max Air heel unit.
