Mirallas, 28, joins New Balance from Nike and will wear its Furon range of boots with immediate effect.
The winger is a further addition to the Boston company’s expanding roster of soccer players that includes 2015/16 Premier League winner Kasper Schmeichel, who signed with the brand in July.
“New Balance is making a huge impact in football and has big ambitions for the future,” said Mirallas. “This is why I am delighted to be joining the exciting brand. I am already impressed with the Furon boots; they are comfortable, look great and will help elevate my game.”
New Balance general manager Richard Wright added: “We are really pleased to be welcoming Kevin into the New Balance family. He is a strong and dynamic player who has proved himself in some of the toughest leagues in the world and on the international stage.
“He is a perfect fit for the brand and we look forward to working together.”
