This is a high-top, lifestyle-oriented version of the UltraBoost that emphasizes sustainable and premium materials. It features a predominantly Core Black upper constructed with rLEA (recycled leather) knit and suede/leather overlays. The design has a chukka-boot aesthetic with exaggerated cross-stitch detailing on the forefoot suede overlay, giving it a moccasin-inspired look. The all-black upper contrasts sharply with a clean white BOOST midsole, while subtle pops of Sonic Ink (a purplish-blue color) can be found on the ankle collar and tongue branding.
