The Air Max 90 FlyEase 'Pink Blue' applies vibrant hues to the first Nike Sportswear silhouette to feature the brand’s easy-entry system. Overhauled on the occasion of its 30th anniversary, the retro runner features a flexible heel that collapses when the foot enters the shoe, then snaps back into place for a secure fit. The rest of the upper makes use of a white mesh base with blue leather overlays and contrasting pink accents, all riding on a solid white midsole.
