Billie Jean King has collaborated with adidas to launch the Here to Create Change campaign, which aims to 'change the future for NYC's young female athletes', following reports that girls in New York City drop out of sport 2.

4 times more often than boys do. Through the campaign, adidas is launching the Billie Jean King Speedfactory shoe AM4BJK, 'created in honour of BJK's permanent footprint on the fabric of female sport', and the tennis legend commented 'I am proud to collaborate with adidas on addressing today's barriers. Together, we can achieve more progress, equality and access for everyone in tennis and beyond'.
