The Nike Air VaporMax 2021 FK Black Anthracite and Flyknit 'Triple Black' are designed with both utility and sustainability in mind. The uppers are made out of stretchy and breathable Flyknit fabric, adorned by the brand’s iconic Swoosh symbol. The Black Anthracite version is made out of 40% recycled content by weight and features two sizable cushioning units that are sleekly integrated with recycled rubber outsoles and bolstered by recycled TPU clips. The monochromatic Flyknit ‘Triple Black’ is a lifestyle runner, with a stitched-on Swoosh and an elastic sock-like collar for easy wear. Both models prioritize comfort while showcasing a stylish all-black aesthetic, making them recognizable classics within the Nike Air line.
