New Balance said it plans to “vigorously defend itself” against a lawsuit from Manchester United’s Marouane Fellaini charging its  boots injured his feet.

The Sun reported that Fellaini’s lawsuit t London’s High Court noted that the footwear Fellaini wore as part of his endorsement deal caused him “loss of enjoyment, inconvenience and impact on performance.” He’s seeking  £2.1 million.

According to ESPN, New Balance countered by saying Fellaini had told the company the boots were “perfect.”

In a statement provided to ESPN on Monday, New Balance wrote, “Although we cannot comment on pending litigation, New Balance can confirm that the company plans to vigorously defend itself and its longstanding record of manufacturing excellence and surpassing the needs of athletes around the world,” the statement said. “New Balance is confident that it has acted appropriately and is grateful for the services historically provided by Mr. Fellaini.”
