In September 2019, adidas commemorated the East Asian Moon Festival by releasing a limited edition of the UltraBoost 4.0. This unique sneaker features a sleek black Primeknit bootie as its foundation, complemented by a midfoot cage adorned with the iconic Three-Stripes branding and an accompanying lace closure. To pay homage to Chinese culture, intricate graphics reflecting the festival are intricately printed on the tongue label and external heel counter. The shoe's overall design is completed with a Stretchweb outsole featuring Continental Rubber for enhanced traction. A standout feature of this special edition is the vibrant orange Boost midsole, which pays tribute to the mooncakes traditionally associated with the Moon Festival.
