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

Kylian Mbappé and Nike are over. Nineteen years, gone in a flash.

The split ends one of the most carefully cultivated relationships in modern sport. Nike spotted him before almost anyone else, signing the Bondy prodigy to a boot deal at just eight years old, when he was still tearing up pitches on the outskirts of Paris. The Swoosh has been there for every major step since.

He wore Nike when he exploded at Monaco. He wore Nike when he ripped through the 2018 World Cup as a teenager and fired France to the trophy in Russia. He wore Nike when he dragged Les Bleus to the brink again in 2022, scoring a hat-trick in that wild final against Argentina. From Paris Saint-Germain to Real Madrid, his boots told the story: this was Nike’s new global football face, the heir to Cristiano Ronaldo as the American giant’s on‑pitch icon.

Twelve signature boots later, including the golden Mercurial Superfly 11 launched only in August, that story has taken a dramatic twist. Those gleaming new boots now look like a farewell edition.

Reports in France indicate Mbappé’s contract with Nike expired on July 31 and has not been renewed. The silence since then has grown louder by the day. For Nike, it is a brutal blow. They had built their football marketing around him at a time when adidas have been clawing back ground in the global battle for dominance.

But the shock is not just that Mbappé is leaving. It is where he is going.

Mbappé bets big on an outsider

He is not jumping to adidas. Not to PUMA. Not even to ambitious challengers like New Balance or Skechers. According to French insider Thibaut Vézirian, Mbappé is set to join forces with a brand that, in football boot terms, barely exists.

All roads point to On.

The Swiss company has been a phenomenon in running. Founded only 16 years ago, On has carved out a huge slice of the market with its distinctive ‘CloudTec’ cushioning, positioning itself as a disruptive performance brand. As of August 2026, the company is valued at around $10.77 billion (£7.95bn). That’s serious muscle for a supposed outsider.

What they have never done is make a football boot.

Mbappé is about to change that. He would walk in as the undisputed face of On’s football project, fronting their first-ever boot and instantly catapulting the launch into the global spotlight. This is not a quiet test run. It is a full‑blown assault on one of sport’s most fiercely contested spaces.

And it is not a standard endorsement.

Vézirian reports that Mbappé’s agreement with On will include equity in the company, paid in shares. He is expected to front his own “sub‑brand” of signature football boots alongside On’s general lines, echoing the kind of tiered ecosystem that turned Jordan Brand into a powerhouse for Nike in basketball.

This is not just a logo on a contract. It is a seat at the table.

From sponsored star to stakeholder

The suggestion is clear: Mbappé will have genuine input on product strategy, design and brand direction. For a 27‑year‑old at the peak of his career, that is a rare level of power.

The move fits the modern athlete archetype. Today’s superstars don’t just collect sponsorships; they build portfolios. Mbappé already has major partnerships with Dior, Oakley and EA Sports. He operates as much like an entrepreneur as a traditional endorser, and On’s rise offers him something Nike could never truly match: the chance to help shape a brand’s future from almost the ground floor of a new category.

The template is already there in On’s own history.

In 2019, they persuaded Roger Federer to walk away from Nike and join them. The Swiss legend didn’t just wear their shoes. He reportedly invested around $50 million for a 3% stake, becoming a shareholder and creative partner. On launched ‘The Roger’ lifestyle line a year later, with Federer involved in design and development. That range has become a staple of the brand.

Federer, though, arrived in the twilight of his career. Mbappé is different. He is at full speed, leading the line for Real Madrid and France, still with a decade at the top in front of him. That is the scale of the coup On are closing in on.

Sports marketing expert Steve Martin, writing in City AM, spelt out the potential impact: “For a challenger brand, his presence would deliver instant global credibility. Every match for Real Madrid, every Champions League night, every France international appearance becomes a global marketing platform.”

That is the prize On are chasing.

A new kind of boot war

Skechers have already shown how quickly the landscape can shift. Their move into football in 2023 with Harry Kane raised eyebrows across the game. A lifestyle and walking shoe specialist going after the England captain? It sounded outlandish. Then Kane signed a lifetime deal, the boots performed, and other players followed. Skechers are now a serious disruptor in the boot market.

On are aiming even higher.

If Mbappé’s deal mirrors the Federer structure, the implications are profound. As Martin put it, the real disruption is not just visibility, but alignment. An equity-based deal flips the dynamic. The player is no longer simply paid to promote a product; he is financially invested in the company’s success.

For Mbappé, the upside is obvious: participation in long‑term value creation, not just short‑term endorsement fees. For On, the benefit is just as clear: their flagship football athlete becomes a stakeholder, not just a billboard.

That alignment changes behaviour. Every Champions League knockout night, every El Clásico, every France game at a major tournament becomes an On showcase. Not because they bought the ad slot, but because their most important shareholder is also one of the most watched athletes on the planet.

High stakes, huge upside

None of this guarantees success. On still have to do the hard part: build an elite-level football boot that can survive the scrutiny of the very best players and the unforgiving judgement of Sunday league dressing rooms.

The launch product must be right. Performance comes first. If the boot fails, no amount of marketing wizardry or equity talk will save it.

But they start from a powerful position. Mbappé is a bona fide global superstar, a walking marketing machine whose every move is tracked in real time. Attach that profile to a credible product, and the upside for On is enormous.

If the partnership works, it could redraw the map for elite boot deals. Other brands will be forced to consider equity structures. Other stars will ask for more than just a cheque and a signature line. Some may follow Mbappé to On. Others will try to replicate the model elsewhere.

What began with an eight‑year‑old in Bondy tying up his first Nike boots has turned into something very different: a generational talent stepping away from the Swoosh to help build a challenger from scratch.

The question now is simple: will Kylian Mbappé just wear the next great football boot, or will he help invent it?
