The Adidas UltraBoost 21 Vivid Red delivers a monochromatic take on a performance running shoe built with sustainability in mind. The crimson Primeknit upper, featuring recycled Parley Ocean Plastic and zero virgin polyesters, rides atop a full-length Boost midsole in the same bold finish. Contrasting black detailing outlines the shoe's revised Torsion system, dubbed Linear Energy Push, and designed to lessen forefoot flexibility for a more responsive ride. A Stretchweb Continental rubber outsole provides a reliable grip.
