Ultra Boost 21 Triple Black

The adidas Ultra Boost 2021 Triple Black features semi-translucent, brownish cages and heel supports that are completely laced in black. The Primeknit structure is visible in other sections, revealing a weave pattern that honors the 1.0 and perforates almost identically at the toe box. To finish off the monochromatic theme, the branding, laces, and soles are in a dark color. Underfoot, the shoe uses Linear Energy Push technology to provide excellent performance.
