adidas Ultra Boost 21 Black Carbon and Carbon Solar Red

The adidas Ultra Boost 21 Black Carbon is a running shoe designed for extreme comfort with Ultra Boost technology in the midsole. This version features a black Primeknit upper for breathability and flexibility, complemented by a synthetic toe cap and mudguard. The iconic three stripes appear on each side in black, while a Solar Red adidas logo is featured on the tongue. The heel is supported by gray Ultra Boost branded material, and the shoe sits on a thick Carbon midsole crafted for comfort and energy return. A black outsole with a Solar Red accent completes the look. The Solar Red accents add a vibrant touch to the otherwise dark design. Released on June 11, 2021, for $180. Meanwhile, the adidas UltraBoost 21 ‘Carbon Solar Red’ highlights the full-length Boost midsole with a metallic gunmetal finish. The Continental rubber outsole is equipped with the updated Torsion system, Linear Energy Push. The black and Carbon Primeknit upper is made in part with recycled Parley Ocean Plastic, ensuring a sock-like fit. Lightweight support comes from a smoky midfoot cage and a silver translucent heel counter, with a Solar Red adidas-branded tongue tag offering a pop of color.
