Kylian Mbappé has worn Nike since he was a kid in Bondy. On Thursday that ended, and the brand that replaced Nike does not currently make a football boot.
On, the Swiss company whose cushioned running shoes have quietly taken over every airport departure lounge in the world, announced its entry into football on September 18 with Mbappé as its first and biggest name. The deal runs 10 years. Terms were not disclosed, but both sides confirmed the structure includes equity, so Mbappé is now a shareholder in the company whose boots he will wear. Thierry Henry has been named On’s Director of Football. The first products are not due until 2027.
Read that order of events again, because it is the part that matters. He signed for a boot that does not exist yet.
What actually happened
Mbappé’s Nike relationship went back to roughly 2006, when he was a seven-year-old in the Paris suburbs, and it ran nearly 20 years through PSG, two World Cup finals and the move to Real Madrid. He is 27, he is the World Cup’s all-time leading scorer, and he was one of the two or three most valuable athlete signatures in Nike’s football portfolio. Losing him is not a rounding error.
What he gets in return is not just a bigger cheque. On’s own release makes the pitch plainly. “Football doesn’t need another sportswear brand to do more of the same,” co-founder and co-CEO David Allemann said. “Football needs new ideas.”
Mbappé’s line was about building rather than endorsing: “From the beginning, what drew me to On was the opportunity to build something entirely new together that will help shape tomorrow’s game.”
He will work directly with On’s engineers in Zurich on boots and apparel. In the meantime he still needs something to play in, so expect him in his existing Nike Mercurials, possibly blacked out, for the next few months.
Who On actually is
If you only know On from the chunky white trainers, here is the short version. Swiss, founded in 2010, made its name on a sole full of hollow rubber pods called CloudTec. Roger Federer joined as an investor and designer in 2019 and the brand went from niche to everywhere. It sells running, tennis and training gear. Until Thursday it sold no football.
The interesting part is not the balance sheet, it is the factory. On’s LightSpray technology builds a shoe’s upper by having a robotic arm spray roughly 1.5km of thermoplastic filament directly onto a mould, in one continuous thread, in about three minutes. No cut panels, no stitching, no glue. The upper is then thermally fused to the sole. On its racing shoe, the Cloudboom Strike LS, that upper weighs about 30 grams. A conventional upper can pass through as many as 200 separate production steps across multiple factories. This one happens in a single room.
That is the actual reason this deal exists. On is not trying to out-market Nike, which would be a losing game against a company that can turn a 1998 advert into a boot drop 28 years later. On is betting it can build a boot in a way nobody else can.
Why the equity is the real story
Boot deals are usually simple. The brand pays the player, the player wears the boots, everyone re-signs or moves on. An equity stake changes the incentive completely. Mbappé does not get paid more if the boot is good, he gets richer if the company is worth more in 2035. That is closer to what Michael Jordan has with Nike than to a standard endorsement, and it is a template every elite player’s agent is going to be looking at this week.
The market noticed too. On’s stock, listed in New York as ONON, rose around 6 percent on the announcement.
Henry is the signing nobody is talking about
Putting Thierry Henry in charge of a football division is not a ceremonial move. He has been working with On behind the scenes since late 2025 on product direction, athlete recruitment and strategy, and his remit covers all three. A running company entering football will get the engineering right and the culture wrong unless somebody in the building knows what a boot needs to survive a wet Tuesday in February. That is the job.
On has also expanded its deal with Sydney Schertenleib, the Swiss international at Barcelona, who joined as a training and lifestyle ambassador in December 2025 and now moves into the football line as well. A brand launching in 2027 with a marquee man and a genuine women’s-game name from day one is doing something a lot of established brands still treat as an afterthought.
Now the fun part: what will an On boot look like?
On has published nothing. So we did what any football fan does with an empty release date, which is guess. Here is our sketch, reasoned from the technology On already sells.
It will almost certainly be laceless. LightSpray’s whole advantage is a seamless one-piece upper. Cutting a lace window into it means adding panels, eyelets and reinforcement, which is exactly the complexity the process exists to delete. Expect something you pull on.
The fit will be sprayed, not stitched. Because the robot controls where the filament goes, thickness becomes a design variable rather than a material choice. Denser spray around the heel and the ankle for lockdown, barely anything over the top of the foot for touch. Nike and adidas do this with separate materials bonded together. On can do it with one thread and a different program.
It will chase a weight number. If a 30-gram running upper is the starting point, the marketing is going to be about grams. The lightest elite boots on the market sit around 170 to 180 grams. A sub-150-gram boot with real stud geometry would be a genuine headline, and it is the obvious place for On to plant its flag.
The soleplate is the hard part. Running shoes push in one direction. Football boots get planted, twisted and studded on at angles that would tear a road shoe apart, and they have to do it on wet grass. This is where a running brand is most likely to get found out in year one, and it is also where On’s pod language could translate into something that looks like nothing else on the pitch.
It will be quiet. On’s design instinct is understated: white, bone, grey, small logo. Football boots have spent a decade going the other way, all volt and fuchsia and chrome. A deliberately plain elite boot on the feet of the most-watched forward in the world would stand out more than another loud one.
The risk
Boots are not trainers. Players are superstitious about them in a way that makes switching genuinely hard, and a new entrant gets exactly one chance at a first impression. If the 2027 boot blisters heels or loses studs, no amount of robotics coverage will save it. On also has to build a whole football apparel and retail operation from nothing while the two incumbents own the shelf space.
And Mbappé still has to play in Nikes for a few more months, which is the strangest detail in the whole story.
What to watch
Three things. First, whether On signs a club, because kit deals are how a boot brand gets taken seriously. Second, who else joins before launch, and whether the equity structure becomes the norm. Third, the moment Mbappé shows up in a blackout prototype, which is how these things always leak.
Football’s boot market has had two real players for 30 years. It just got a third, and the third one owns a robot.
