The adidas Ultra Boost 2021 Triple Black’s majority of the fixtures on the upper part share a neutral color and has Boost cushioning. Its cages and heel supports are both given a brownish, slightly translucent appearance, and are totally laced in black. The Primeknit construction underneath is visible in other places. 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.
