The adidas Ultra Boost DNA 4.0 Core Black features a black adidas Primeknit upper with a black midfoot cage and supportive heel counter, and black laces complete the look. The Primeknit yarn is primarily made from the sustainable material Primeblue, which is made from recycled ocean plastic, and no virgin polyester is used. The black insole has the word "BOOST" in a bubbly white font. The outer sole is black and white rubber. The white midsole has the Boost’s signature cushioning.

  The adidas Ultra Boost DNA 4.0 Core Black was released in February 2021, at a retail price of $180.
