The popular color combination of Black and Red are coming to the latest iteration of the adidas Ultra Boost 4.0 for this holiday season. The sneaker’s Primeknit upper is covered in red for its majority with black accents throughout, while more tonal black is used for the Three Stripe branding on the sides, eyelets, laces, TPU heel counter and lining. Finally, red for the lacing cage, a contrasting white Boost midsole and black rubber outsole tops it all off.
