In June 2019, adidas introduced the UltraBoost 1.0 S&L 'Black Red Blue' running shoe. Tapping into Three-Stripes innovation, the upper blends suede and leather for a technical, contemporary look. Breathable and lightweight, the Primeknit upper promotes a snug fit and incorporates a lace-through leather cage at the midfoot for superior lockdown. Red suede wraps around the toe and hits the heel for a pop of contrast while a blue suede panel at the heel counter compliments the silhouette.
