adidas ZX 9000 Concepts

adidas released the ZX 9000 Concepts as part of its A-ZX series, featuring a new sneaker for every letter of the alphabet. This shoe pays tribute to the Boston Marathon with shimmering material, reminiscent of the emergency blankets awarded to runners. The reflective upper resembles a sheet of foil, complemented by red, white, and navy blue accents. Each side of the shoe is unique; the left has three stripes while the right showcases one stripe and a red midsole patch. The navy blue adidas logo is prominently displayed on the tongue. Released in September 2020, this model retailed for $140.
