The adidas x Kolor Ultra Boost 3.0 boasts an attractive design, sporting a black Primeknit upper that perfectly complements the striking blue cage. Enhancing its visual appeal, the shoe features a metallic gold heel cup and a vibrant yellow inner lining. The collaboration continues to impress with a black Boost midsole and a standout Solar Red outsole. Originally released in Japan in February 2017 along with the Kolor x Ultra Boost Uncaged, the Ultra Boost surprised sneaker enthusiasts with an unannounced drop at the adidas flagship store in NYC. Quantities were limited, adding to the exclusivity of this highly sought-after footwear.
