The NMD_R1 "Metallic Blue Boost" features monochromatic black coloring on its breathable knit upper, allowing the sneaker's cushioning system to shine. An iridescent blue finish is applied to the full-length Boost midsole, which is further enhanced with a reflecting coating. Welded three-stripes are similarly given the reflective treatment, while dual NMD plugs in the midsole maintain the classic adidas NMD aesthetic.
