An iconic sneaker gets an eco-conscious makeover with the Billie Eilish x Nike Air Force 1 Low ‘Sequoia.’ Eilish and Nike branding appear on the sockliners made from recycled foam and the outsole is constructed from Nike Grind. The upper in dark green with tonal stitching features textile left over from an earlier AF1 High collab with the pop star and is delivered in a patchwork array of synthetic suede.
