CHICAGO – The National Women’s Soccer League and Nike Friday signed a long-term agreement that extends a partnership that began with the league’s formation in 2012.

The length of the agreement was not revealed in a press release.

“Since the beginning, Nike and the NWSL together have driven significant growth of this great game for all, in the U.S. and around the world, and we couldn’t be more excited to extend this foundational partnership well into our second decade of play,” NWSL interim CEO Marla Messing said in a statement. “With this agreement, Nike is showing the world again what it means to support athletes, helping to grow the opportunities available for them to compete, and supporting the NWSL and its athletes in its effort to remain the premier destination for the world’s most elite players.”

The most substantial agreement in NWSL history, the partnership extension represents Nike’s significant commitment to the sport, the NWSL and its players and clubs. Specific focus will be placed on elevating performance through research in footwear and apparel innovation, and growing engagement by highlighting athletes both on and off the field, the press release stated.

Added Becca Kerr, Nike vice president and general manager of North America Women’s: “Nike continues to champion long-term change in women’s sports. Our ongoing partnership with NWSL and our continued investments in soccer through partnership and grassroots efforts are catalyzing action and progress to help drive that change.”
