The Billie Eilish x Nike Air Force 1 High ‘07 SP ‘Mushroom’ pairs a monochrome palette with a sustainable build. The chart-topping pop star dresses the high-top in ultra-soft synthetic nubuck, made from post-consumer recycled content and finished in a one-note beige hue. In addition to standard laces, the upper is secured with large adjustable straps that reflect the vocalist’s signature oversized style. Billie Eilish branding is stamped on the sockliner, while her Blohsh logo adorns the molded lace dubrae. Anchoring the sneaker is a tonal rubber cupsole made in part with Nike Grind.
