Medical Warning Links Player Boot Changes to Mbappé's Recent Injury

Kylian Mbappé, the Real Madrid striker, recently sustained a left knee injury, bringing to mind a prior warning. Spanish physical therapy specialist Ángel Villanueva, who specializes in knee injuries and ACL rehabilitation, had cautioned days earlier that changing sports boots could temporarily elevate injury risks. This warning, issued by Villanueva, director of "OMNIA Fisioterapia Majadahonda," concerning the impact of switching footwear on players, coincided with Mbappé's move from Nike to the Swiss company On. The specialist explained that "any change in the boot, whether in its design, studs, stiffness, cushioning level, or weight, leads to a slight alteration in biomechanics, the load on the feet, ankles, knees, and muscle chains, temporarily increasing the risk of injury." Just days after these warnings, Mbappé suffered his left knee injury during France's match against Turkey. He had scored the sole winning goal in the 54th minute before showing signs of pain and subsequently leaving the field. This match marked Mbappé's first official appearance wearing the new On boots, signaling the start of a new phase with the Swiss company this September, following many years with Nike. Mbappé is scheduled to return to Real Madrid for additional medical examinations, as reports have confirmed his left knee injury.
