adidas Ultra Boost 21 Parley Carbon

The adidas Ultra Boost 21 Parley Carbon is a long-distance running shoe built with Ultra Boost technology as a collaboration between the two brands. This iteration of the adidas Ultra Boost 21 features an upper made with a mix of lightweight and breathable materials. The upper is mostly black, with a shiny black mudguard that features light blue stitching. Light blue also forms the heel counter, which is branded with the Ultra Boost name. The shoe features black laces along with Sandy Beige secondary laces secured to the sides of the shoe. There is a heel pull tab also in Sandy Beige. The tongue features a branded adidas and Parley logo patch, while another black tab with both companies’ branding appears on the heel. The shoe sits atop a textured white sole with Ultra Boost technology. What we like best about this shoe is the secondary lacing system, which adds a pop of color and unique design. The adidas Ultra Boost 21 Parley Carbon was released on December 31, 2021, for $220.
