In a move that signals the company’s largest investment in soccer in North America, Adidas and Major League Soccer have extended their long-term partnership through 2024. Terms were not disclosed.

The six-year deal makes Adidas the official supplier partner for the league, its clubs, youth academies and youth-affiliated clubs.

“Sport is the epicenter of our culture and, in the U.S. and Canada, soccer is the most popular sport for young people to play,” said Mark King, president of Adidas North America.

“Our partnership with MLS puts Adidas at the core of sport in North America, allowing us to make a positive difference in an athlete’s game and life. Built from athlete and consumer insight, we are looking to create the future of sport and bring new and different things to the game the world has never seen before.”

Under the terms of the deal, Adidas will outfit MLS teams with uniforms, footwear, training gear and sideline apparel. The company will also provide the league with its official match ball.

“Major League Soccer has built a legacy with Adidas that has been essential in the rise of our league,” said MLS commissioner Don Garber. “Adidas has been a major collaborator with us since the inception of MLS, and we are proud that our partnership with this brand will continue to enhance the growth of the game in North America for many more years. We will work with Adidas on innovative concepts to showcase the sport and our elite athletes, and we will intensify our mission to develop top North American soccer players for generations to come.”

The deal also includes local social media initiatives including Adidas’ new Creator’s Network that will include content from league supporters and influencers.

Adidas and Major League Soccer began their relationship at the league’s inception in 1996 with Adidas partnering with the Columbus Crew, Kansas City Wiz and D.C. United. In 2004, the partnership was expanded to encompass the entire league.
