Coming fresh off of Earth Day, Billie Eilish added an eco-friendly twist to one of Nike's most storied models with the Nike Air Force 1 Billie Eilish Mushroom. With a recycled Durabuck upper and Nike Grind midsole, the Nike Air Force 1 Billie Eilish Mushroom takes a more sustainable approach to achieve a high-end look. Its monotone Mushroom palette emphasizes its unique, chunky mid-foot straps that borrow from both the Alpha Force Low and Air Trainer 3 designs. From there, a classic Nike Air heel embroidery completes this collaboration. 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.
