The year 2018 sees the launch of several new Speedfactory products, including the key city editions for Los Angeles (AM4LA), New York (AM4NYC), Paris(AM4PAR), Shanghai (AM4SHA), London (AM4LDN) and Tokyo (AM4TKY). In addition, adidas releases limited editions throughout the year, such as the AM4BJK. Inspired by legendary female tennis player Billie Jean King, this advanced performance shoe is built and assembled at the Speedfactory in Atlanta, USA, and was launched to mark the start of the 2018 U.S. Open. At the end of the year, the series is complemented by running shoes resulting from a collaboration with local L.A. and NYC creators such as celebrity stylist Kwasi Kessie and the Brooklyn Ballet.
