Released in August 2018 to coincide with the US Open, the adidas Speedfactory AM4BJK pays tribute to tennis legend Billie Jean King. The streamlined silhouette, assembled at adidas’ digital Speedfactory facility in Atlanta, carries a flexible knit upper in blue and white – a colorway inspired by the adidas shoes that King wore during her “Battle of the Sexes” match against Bobby Riggs in 1973. The production run was limited to just 300 pairs. In perfect condition...never worn!
