Kylian Mbappé Leaves Nike for On: A New Era in Football Boots

Kylian Mbappé has ended a 20-year relationship with Nike to sign a headline boot deal with Swiss challenger brand On, a move that jolts the football boot market and signals serious intent from a newcomer.

The France captain, who joined Nike as a nine-year-old prodigy, walks away at the end of his contract after the World Cup and straight into a project designed to reshape how a brand enters football. On, best known for its rapid rise in running and growing presence in tennis, is now aiming straight at the game’s elite.

Mbappé will not just wear the boots. He will own part of the company.

Mbappé joins Federer in On’s football gamble

On, headquartered in Zurich, already has one global icon embedded in its story. Roger Federer left Nike to join the brand towards the end of his career and is now a shareholder. Mbappé follows a similar path, but at a very different stage of his life: 27 years old, at the peak of his powers, and still one of the defining faces of modern football.

He is not simply a sponsored athlete in this deal. Like Federer, Mbappé becomes a shareholder, tying his long-term reputation to the success of a company that is only just stepping onto the football pitch.

“From the beginning, what drew me to On was the opportunity to build something entirely new together that will help shape tomorrow’s game,” Mbappé said. “I want to bring my experience and perspective into what we create, push what’s possible through innovation, and always stay true to the joy of football. We have a shared dream, and this is only the beginning.”

On has appointed Thierry Henry as its football director, another statement of ambition. One of France’s greatest forwards now sits at the heart of a project built around its current superstar.

A first step: Lightspray Prototype

The brand’s arrival in football is no longer theoretical. This week, On unveiled its first boots, the Lightspray Prototype. For now, it is a glimpse of what is coming; the boots will hit the mass market next year, with training kit to follow as the company pushes deeper into the sport.

This is a crowded, unforgiving space. Nike and Adidas still tower over everyone else, their boots on the feet of more than 40% of players at this summer’s World Cup, according to data compiled by retailer Fútbol Emotion. Puma sits a distant third at around 10%.

The rest are scrambling for relevance. Under Armour, New Balance and Skechers — whose boots are worn by England captain Harry Kane — have all tried to break through. None has yet shifted the balance of power at retail level in any meaningful way.

On believes Mbappé can change that equation.

A blow for Nike

For Nike, Mbappé’s departure stings. This is not a fringe player walking out the door. This is one of the core faces of Nike Football, a World Cup winner, a Champions League star, and the frontman for some of the company’s most prominent global campaigns.

“Kylian’s journey with Nike began when he was nine years old,” Nike said in a statement. “Over nearly two decades, we’ve shared moments that shaped the game and he has been an important part of Nike Football. We are proud of what we achieved together on and off the pitch.”

The words are warm, but the reality is stark. Two years ago, Nike also lost Barcelona and Spain sensation Lamine Yamal to Adidas. Now Mbappé, another generational talent, has stepped away. In a market where visibility on the biggest stages is everything, those exits matter.

A new kind of boot war

Boot deals used to be simple: brand, cheque, signature, photoshoot. Mbappé’s move hints at a different future, where superstars do not just endorse products but sit at the table as partners, shaping design, strategy and long-term direction.

On is betting that this deeper relationship, backed by Henry’s football authority and Federer’s existing influence, can crack a market that has chewed up challenger brands for years. Nike and Adidas still dominate the World Cup, the Champions League, the grassroots pitches and the shop walls.

But a 27-year-old global icon tying his prime years to a Swiss upstart changes the conversation. If Mbappé’s boots catch on with the next generation, the established order may find itself under a kind of pressure it has not felt in two decades.
