The adidas UltraBoost 4.0 DNA "Core Black" takes on a clean, simple, and ultra versatile colorway. The ventilated knit upper in black forms a sock-like construction with high-performance recycled PRIMEBLUE material, while resting atop the signature white BOOST midsole—which creates comfort and softens a runner's stride. The midfoot cage features adidas's trademark Three Stripes in black, giving off a subtle black-on-black look. Following the monochromatic theme is a black Continental stretch-web outsole to match.
