The adidas UltraBoost 22 ‘Triple Black’ updates the lightweight runner with a stealthy design and sustainable materials. A one-note finish suffuses the Primeknit upper, made with a 50/50 blend of recycled Parley Ocean Plastic and recycled polyester. The lightweight build rests on a full-length Boost midsole, enhanced with adidas’ Linear Energy Push system for enhanced responsiveness. Underfoot, the Stretchweb outsole features Continental Better Rubber for optimal grip.
