The adidas women’s UltraBoost 22 ‘Black White’ combines a sustainable build with a sleek, monochrome aesthetic. Built on a custom last specifically tailored to the female foot, the blacked-out Primeknit upper is composed of 50% Parley Ocean Plastic and 50% recycled polyester. Responsive cushioning arrives via a full-length Boost midsole in a contrasting white finish. The Stretchweb outsole, made with Continental Better Rubber, features adidas’ updated Torsion system, dubbed Linear Energy Push.
