The adidas UltraBoost 4.0 'Japan' sneaker was launched exclusively at atmos in August 2019. Paying tribute to the country, the UltraBoost 4.0 underwent a makeover with notable details such as the Japanese flag artfully stitched onto the tongue as a patch. Reflecting Japan's extravagant pyrotechnic festivities, the shoe's white Primeknit upper features vibrant firework graphics. Enhancing comfort, the shoe incorporates Boost cushioning and is completed with a tonal rubber outsole.
