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 Nike Air Force 1 Billie Eilish Mushroom released in April of 2022 and retailed for $170.
