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

Kylian Mbappé and Nike always felt inseparable. The kid from Bondy signed to the Swoosh at eight years old, long before the cameras, long before the Bernabéu, when his stage was a suburban pitch on the edge of Paris.

That logo was on his boots when he tore through defences at Monaco. It was there when he dragged France to the 2018 World Cup title as a teenager in Russia. It was there again when he hit a hat-trick in the 2022 final against Argentina, almost hauling Les Bleus to back‑to‑back crowns on his own.

From Paris Saint-Germain to Real Madrid, as Cristiano Ronaldo’s era as Nike’s leading man began to fade, Mbappé stepped into the spotlight. He became the face of the brand’s football business, the modern poster boy for the Mercurial line.

Twelve signature boots later, that era is suddenly over.

A 19-year relationship cut short

Mbappé, now 27, has already walked away from Nike. The partnership that began when he was a child and ran for 19 years has been brought to an abrupt halt. Online reports indicate his contract expired on July 31 and was not renewed.

For Nike, it is a brutal blow. Mbappé had effectively replaced Ronaldo as the frontman of their football portfolio. Losing him at the peak of his powers, just as adidas have been turning up the heat in the boot wars, is as damaging symbolically as it is commercially.

Yet the twist is not that he is leaving. It is where he is going.

He is not heading to adidas. Not to PUMA. Not even to newer players like New Balance or Skechers. According to French insider Thibaut Vezirian, Mbappé is set to align with a brand that, in football terms, barely exists.

A running brand steps onto football’s biggest stage

On, the Swiss sportswear company founded only 16 years ago, has built its name in running. Their ‘CloudTec’ cushioning turned them into a disruptive force in that market, and by August 2026 the company carried a valuation of around $10.77 billion (£7.95bn).

What they have never done is make a football boot.

That is about to change. Mbappé is expected to become the face of On’s first-ever football boot line, instantly turning a debut product into a global talking point. This is not just a big signing; it is a full‑scale land grab in one of sport’s most fiercely contested spaces.

And this deal goes far beyond a standard endorsement.

Not just an ambassador – an owner

Vezirian reports that Mbappé’s agreement with On will include equity in the company. Shares, not just a signature on a contract. The plan is for the Real Madrid star to front his own “sub-brand” of boots, sitting alongside On’s general releases.

That means influence. On product strategy. On brand direction. On how the line looks, feels and evolves.

Given Mbappé’s status and reach, the ambition is obvious: build something in football that carries the same cultural weight Jordan Brand holds in basketball under Nike’s umbrella. A standalone identity, powered by a superstar, but with its own gravity.

Why walk away from Nike? The money matters, of course. But this is also about control and legacy. Modern athletes increasingly see themselves as entrepreneurs as much as players. Mbappé already has heavyweight partnerships with Dior, Oakley and EA Sports. Owning a slice of a rising sportswear company fits that profile perfectly.

Federer showed the way

If anyone doubts whether On can handle a name of Mbappé’s stature, their track record is instructive.

In 2019, just nine years after its founding, On persuaded Roger Federer to leave Nike and join them. The Swiss icon did more than just lace up their shoes. He reportedly invested $50 million for a 3% stake, becoming a shareholder as well as an ambassador.

On and Federer then launched ‘The Roger’ – a limited-edition lifestyle trainer released in 2020. Federer was heavily involved in its design and development. The line has since become a staple in the brand’s catalogue.

Federer arrived in the twilight of his career. Mbappé is arriving at the peak of his. That changes the scale of the bet entirely.

Sports marketing expert Steve Martin summed it up in City AM: “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.”

A new playbook for boot deals

The impact of this kind of move is already visible elsewhere. Skechers stunned the industry in 2023 by signing Harry Kane to a lifetime deal as they launched their first football boots. The decision raised eyebrows at first, yet the American brand has quickly gained a foothold in the market, with more players following Kane’s lead.

On and Mbappé are now poised to push that disruption further.

Martin highlighted why this model cuts deeper than traditional sponsorship: “Unlike traditional advertising, this is not reach that can be bought – it is earned through performance at the very highest level of the game. But the real disruption would not just be visibility. It would be alignment. An equity-based deal transforms the relationship.

“Instead of Mbappé being paid to promote a product, he becomes financially invested in building the business. A structure combining a base fee, performance bonuses and a meaningful equity stake would align athlete and brand in a way that traditional sponsorship never can.

“For Mbappé, the upside is obvious: participation in long-term value creation. For the brand, the benefit is equally powerful: a global superstar who is not just the face of the product, but a stakeholder in its success.”

That is the crux. This is not just about which logo appears on a boot. It is about who owns the story.

The risk – and the upside

There is plenty that can go wrong. On have never produced a football boot. The first model must perform at elite level and sell at scale. The design has to resonate with kids on playgrounds and pros in dressing rooms. The technology has to convince the most scrutinised feet in world football.

But On are not starting from zero. They have engineering pedigree from running. They have already navigated a high-profile, equity-based partnership with Federer. Now they add one of the game’s most marketable and explosive talents.

Mbappé, for his part, steps into uncharted territory. He leaves behind the comfort, heritage and global muscle of Nike for a challenger brand and a far greater stake in the outcome.

If it works, he will not just have worn an iconic boot. He will have helped build the company that made it.

And in a sport where the biggest stars are increasingly thinking beyond 90 minutes, that might be the most powerful statement of all.
