The Billie Eilish x Nike Air Force 1 Low ‘Mushroom’ reconvenes the creative partners on a sustainable build that coincides with the 40th anniversary of the iconic silhouette. A one-note tan hue permeates the patchwork upper, which combines a textile base with irregular synthetic suede scraps left over from Eilish’s previous AF1 High collaboration. The pop star’s Blosh logo decorates a pair of molded lace jewels, while dual Nike and Billie Eilish branding appears on a sockliner made with recycled foam scrap. The monochromatic theme continues on the outsole, composed of Nike Grind and featuring the instantly recognizable pivot-point traction pattern.
