The adidas UltraBoost 4.0 “White Multicolor” is a colorful look for the fourth iteration of the popular Boost-cushioned running shoe. This fresh look for the UltraBoost has a predominantly whited Primeknit upper with multicolor thread intertwined into the stripe-textured weave. Helping the whole silhouette achieve a crisp and eye-catching look, the TPU cage and heel counter come in bright white, as do the inner lining, laces, Boost midsole, and Continental rubber outsole. Metallic silver detailing for the “UltraBoost” branding on the heel counter completes the clean colorway. The adidas UltraBoost 4.0 “White Multicolor” released on January 1, 2019.
