The adidas Ultra Boost 2021 Triple Black’s majority of the fixtures on the upper part share a black color and has Boost cushioning. ​ ​ Its cages and heel supports are both given slightly shiny appearance, and are totally laced in black. The Primeknit construction on the upper comes as well in a total black color. The weave pattern, which perforates almost identically at the toe box, pays homage to the 1.0. Next, a dark shade is added to the branding, laces, and soles to complete the color scheme. Linear Energy Push technology is featured underfoot. ​ ​ The adidas Ultra Boost 2021 Triple Black was released on 4 February 2020 and retailed at $180.
