The adidas Ultra 4D in an OG Ultra Boost-inspired colorway is a hybrid model that blends design elements of the Futurecraft 4D and the Ultra Boost in one. Donning stealthy black Primeknit uppers which bear the familiar knitting pattern seen on the Ultra Boost 1.0, alongside matching laces and lace cage, the silhouette is topped off with a purple heel counter and black 4D-printed midsole.
