The adidas UltraBoost 22 ‘Vivid Red’ dresses the lightweight performance runner in fiery hues. A bold crimson finish saturates the sock-like Primeknit upper, featuring a 50/50 blend of recycled Parley Ocean Plastic and recycled polyester. Foam padding lines the back of the collar for improved comfort, while a translucent heel counter provides rearfoot stability. The sneaker rides atop a matching red Boost midsole with adidas’ Linear Energy Push system for enhanced energy return. Underfoot, the Stretchweb Continental Rubber outsole delivers grippy traction in wet or dry running conditions.
