The adidas 4D Fusio ‘Black Ultra Purple’ treats the sneaker’s Primeknit textile upper with a color-fade effect that transitions from white to dark grey. A similar gradient design is applied to the TPU cage that wraps around the midsole, featuring a violet around the heel and a contrasting pop of yellow at the toe. The fluid finish is offset by a stark black 4D midsole, rendered in a data-informed lattice structure that’s created by blending light, oxygen and liquid resin.
