About the adidas UltraBoost 21 'Vivid Red'

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 polyester, 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 reliable grip.
