The Nike Air VaporMax 2021 FK Particle Grey Liquid Lime is a slightly redesigned version of the FlyEase-enabled Vapormax 2020. A breathable shoe, this sneaker features a greyscale arrangement finished off by light liquid lime and deep blue accents. Partly made out of recycled materials, this shoe has deep blue Nike Swooshes with liquid lime borders, plastic reinforcement around the foot, and pull tabs on the heel and tongue. Underfoot it features full-length air cushioning. The Nike Air VaporMax Particle Grey Liquid Lime 2021 FK was released on the 26th of May, 2021, at a retail price of $200. Additionally, the Nike Air VaporMax 2021 Flyknit ‘Grey Light Liquid Lime’ adds neon accents to a lifestyle runner built with at least 40% recycled content by weight. The upper is composed of breathable grey Flyknit with translucent green TPU on the toe cap and external heel counter. Buoyant cushioning arrives via a full-length VaporMax unit made with approximately 50% recycled materials, while the rubber outsole incorporates Nike Grind, made up of post-industrial manufacturing scraps.
