Released in January 2018 in celebration of Chinese New Year, the adidas Ultra Boost 4.0 'CNY' showcases a striking two-tone design and exclusive holiday-inspired elements. The shoe boasts a distinctive marble finish on its laces and lining, as well as a circular tongue patch featuring a Chinese character encompassed by sharp teeth - paying tribute to the Year of the Dog. The upper is meticulously crafted from a blend of black and red yarns, while the midfoot cage and heel cup remain solid black. Furthermore, the contrasting white Boost midsole is coupled with a vibrant red Continental Stretchweb outsole.
