It’s not a new pair of shoes shaking up the game this morning, it’s a contract. Kylian Mbappé is leaving Nike, the brand he has been tied to since the very beginning of his career, to sign with On, the Swiss outfitter previously known for running and tennis. Here is why this signing goes far beyond a simple sponsorship transfer.
A footballer, but not just an ambassador
On's official press release is clear on this point: Mbappé will work directly with the brand's product teams, integrating his high-level experience into the development and testing of future football boots and apparel. In other words, he isn't here to pose for photos in cleats; he is being presented as a product development partner.
This logic is not new for On; it has been fundamental to the brand in running through a culture of innovation and Swiss engineering, embodied by CloudTec and later by LightSpray, its robotic manufacturing technology introduced in 2024, which constructs a shoe upper from a continuously sprayed filament. On is now applying this same method to football, with the stated ambition of producing extremely light and precise footwear.
Alongside Mbappé, two other figures are shaping this shift: Thierry Henry, named the brand's Director of Football after working behind the scenes on the project since the end of 2025, and Sydney Schertenleib, a Swiss international and FC Barcelona player who joined On in December 2025 and is now associated with product development for women's football.
How a sponsorship deal became a sports business earthquake
Several factors explain why this announcement goes beyond the standard framework of a simple equipment manufacturer change:
- A historic break. Mbappé had been tied to Nike since his professional debut. Seeing him move to a player from the world of running, with no prior football footprint, is a choice that reshapes the landscape rather than simply extending it.
- A shareholder position, not just an image one. According to several French sports media outlets, the agreement is set to span ten years and would make Mbappé a shareholder in the brand, a status that goes far beyond the traditional image contract between an athlete and their outfitter.
- A "day-one" bet rather than buying legitimacy. On had never operated in football before this announcement, meaning the brand is building its sporting credibility directly around Mbappé, Henry, and Schertenleib, rather than buying into an already established history.
What this says about 2026
This signing perhaps tells the story less of a player changing sponsors than of a power dynamic shifting: challenger brands, capable of combining cutting-edge engineering and shared governance with their athletes, are becoming credible rivals to the historical giants of the football business. It remains to be seen whether the product bet will live up to its promises on the pitch, or if the operation will remain primarily a strategic and financial masterstroke.
