Most trainers spend years trying to look effortless. The Loewe x On LightSpray Cloudmonster actually is, technically speaking, and the difference matters more than you’d think.
Here’s what happened: On developed a process called LightSpray™, which sprays a continuous filament directly into the shape of an upper in a single step. Three minutes. No stitching, no panels cut and assembled, no conventional construction sequence. The upper forms in one go, sets almost immediately, and what you’re left with is a shoe that looks genuinely unlike anything else on the shelf right now—not because a designer tried hard to make it look different, but because it was made completely differently.
It sits on On’s Cloudmonster Hyper midsole with Helion™ HF cushioning underneath, so the sole is doing familiar, performance-credible work. Above that, though, the upper is a single semi-translucent surface that doesn’t behave like footwear is supposed to behave. And honestly? That’s where it gets interesting.
You’ll Spend The First Five Minutes Just Trying To Figure It Out
That’s not a criticism. That’s the whole experience.
Because most shoes communicate. You can look at a trainer and read its construction — where the panels join, where the reinforcement sits, where someone made a decision about structure versus flexibility. That visual language is so embedded in how we understand footwear that its absence reads as almost unsettling.
The Loewe x On LightSpray Cloudmonster removes that language almost entirely. The upper becomes a single, quiet surface. No seams to trace, no construction logic to decode. Just form, sitting on top of that familiar Cloudmonster sole, and a strange sense that whatever you’re looking at is closer to a cast than a construction.
Luxury trainers typically go out of their way to show you the craft. The hand-stitching, the premium materials, and the evidence of someone’s labour are built into the object. This one shows you the process instead, and specifically, the moment right after the process stopped. It’s a subtle but genuinely interesting repositioning of what “craft” means in 2025.
The Socks Are Doing More Work Than You’d Expect
Each pair comes with three LightSpray socks—Fluo Yellow, Fluo Green, and Teal—and because the upper is semi-translucent, swapping them doesn’t just change the colour of your sock situation. It changes the entire read of the shoe.
Teal is the restraint option. It pulls the whole thing back into something quieter, almost archival, the kind of colourway that photographs well in a design magazine. Fluo Yellow is the confrontational one — clinical, sharp, the kind of colour that has no business being elegant and somehow is anyway. Green sits in the middle, slightly unresolved, which sounds like a criticism but actually gives it the most interesting personality of the three.
So here’s what On and Loewe have actually built: a shoe with three distinct identities and no fixed default. You’re not buying a colourway. You’re buying a system. For a collaboration at this price point, that’s a quietly clever move, and it stops the Cloudmonster from becoming the kind of beautiful object you buy once, photograph twice, and never touch again.
The Rest Of The Collection Is More Legible, And That’s Fine
The Loewe x On drop also includes the Cloudsolo, returning in updated bicolour options across Teal, Sand, and Burgundy, alongside the Cloudtilt Hi, which steps into a hi-top silhouette with tricolour combinations.
Both are easier to wear and easier to understand. They occupy the fashion-performance sweet spot that collaborations like this aim for, and they’ll be the ones most people actually reach for on a Tuesday morning.
But easier to wear isn’t the same as more interesting to own. The LightSpray Cloudmonster isn’t trying to win on wearability. It’s making a different argument entirely, that how something is made can be as compelling as how it looks, and that the two don’t have to be in opposition.
Blackwall’s Campaign Film Is Doing Exactly What It Should
The campaign, directed by visual artist duo Blackwall, puts the LightSpray process on screen rather than keeping it behind the scenes. Saturated colour fields, deliberate pacing, and the spray nozzle present in the visual language rather than edited out for aesthetic cleanliness.
There’s no performance energy here, no borrowed athleticism, no suggestion that you might want to run in these. Instead, the film treats the shoe like what it actually is—a manufacturing process made wearable—and builds the visual world around that idea.
Three Minutes To Make. Longer Than That To Fully Understand
That’s not a knock. Some objects take time.
The Loewe x On LightSpray Cloudmonster doesn’t fall into something familiar the more you look at it, and that’s genuinely unusual for a trainer, even at the upper end of the market. It keeps a slight strangeness about it, as if it still belongs to the act of making, not the business of packaging
Whether you wear it every day or only pull it out occasionally while mostly just admiring it, the shoe makes a real point about what footwear can be when the process becomes the design. In a space full of trainers that go to great lengths to pretend they were never designed at all, that kind of honesty feels refreshing.
And for what it’s worth, the fluo‑yellow sock against the semi‑translucent upper is an unhinged, undeniable hit. Wear it.
