Mbappé's boot switch ends in a goal and a scare

France beat Turkey 1-0 in their UEFA Nations League fixture on 25 September 2026, with Kylian Mbappé getting the goal that decided it. It was also his first competitive outing in prototype boots from On, the Swiss brand he's been linked with as a new footwear partner after years in a different setup. The debut didn't stay clean: Mbappé suffered a knee injury during the game, according to Footy Headlines, which has been tracking the boot switch closely.

Club / player

Mbappé is one of the most recognisable forwards in the game and a regular starter for France. Specific figures for his age, club and international record aren't part of the Footy Headlines coverage of this story, so we're not attaching numbers here, but the profile of the occasion, the goal, the win, the injury, is exactly the kind of high-visibility moment a new boot deal is built to showcase or, in this case, complicate.

Brand

On is the Swiss sportswear brand best known for running shoes, now pushing into elite football. Putting Mbappé, one of the biggest names in the sport, into a competitive match in prototype boots is On testing its new silhouette in the harshest environment available: a live international, under full television coverage, with nothing hidden from view.

Leak or release status

These are prototype boots, not a retail product. Footy Headlines had already published close-up images of the design before the France game, and this Turkey fixture marked their first appearance in an actual competitive match rather than training. Nothing here has been confirmed as a release, and On has not put a product name or launch date on record through the coverage available.

Visual description

Footy Headlines' own framing, calling this the best look yet at the silhouette, tells you the prototype has been visible mainly in glimpses up to now. Beyond that, no specific colourway or construction detail has been laid out clearly enough to describe with confidence, which is normal for boots still in testing rather than production.

Fan reaction

The reaction has split down an obvious line. Some fans are intrigued by a genuine heavyweight signing for On in a sport the brand hasn't cracked before. Others jumped straight to the injury, with Footy Headlines itself asking outright whether the knee problem could be related to the new boots, a question the outlet raises rather than answers.

Our verdict

Nothing here confirms a link between the boots and the injury. No source has offered medical detail on what Mbappé actually suffered, how serious it is, or how long he might be out, and the causal question around the boots is speculative rather than established. What is fair to say is that debuting genuinely untested equipment on a global forward, in a competitive international, is a decision that now looks a lot riskier in hindsight than it did on Thursday. If On wants this kind of moment to read as a marketing win rather than a cautionary tale, the next step is proving the product had nothing to do with what happened, not just hoping the goal gets remembered louder than the injury.
