The adidas UltraBoost U 'Black' arrived in July 2019 as a continuation of the brand's revolutionary running franchise. This edition is optimized for cooling comfort with a Primeknit upper that features ventilating sections in key zones. The shoe is prepared with blacked-out Boost cushioning to help keep a minimalist, tonal appearance while comforting steps. Continental Rubber tread is rendered in a Stretchweb design to allow optimal flex.
