Running shoes have evolved rapidly over the past few years.
What once felt futuristic – carbon plates, oversized midsoles, ultra-light foams – has quickly become the industry standard. In a market now crowded with high-stack super trainers, genuine innovation feels increasingly difficult to come by.
That’s precisely what makes the On Cloudmonster 3 Hyper Lightspray so fascinating.
At first glance, the 205g shoe looks unlike almost anything else currently on the road. The exaggerated CloudTec midsole, sculpted silhouette, and laceless sprayed-on upper give it a distinctly futuristic identity – one that feels more concept prototype than conventional running shoe.
Yet beneath all the visual experimentation lies a surprisingly cohesive ride experience.
Changes The Feel Completely
The headline feature is undoubtedly the LightSpray upper itself. Instead of relying on a traditional engineered mesh construction, On uses a robotic spraying process that creates an ultra-light one-piece upper with minimal material and fewer components overall.
The result is an upper that is breathable and lightweight, and not an issue for Singapore’s heat and humidity. There’s very little excess here – no bulky padding or unnecessary layering – allowing the shoe to feel streamlined and race-oriented from the moment it goes on foot.
I struggled a little to get the shoe on (perhaps I needed to size up half a size more), but the fit is noticeably snug and performance-focused. Once moving, the upper begins to disappear into the run itself. It creates a close, connected sensation that complements the shoe’s highly responsive ride.
And the ride is where the Cloudmonster 3 Hyper Lightspray truly starts to shine.

Surprisingly Smooth
The aggressive rocker geometry creates an effortlessly smooth rolling transition, constantly guiding the runner forward with each stride. Combined with On’s dual-density Helion HF foam setup and triple-layered CloudTec cushioning, the shoe delivers a ride that feels energetic and lively without becoming unstable or overly soft.
Importantly, the cushioning still retains a sense of control.
While many modern max-cushioned trainers lean heavily into softness, the Cloudmonster 3 Hyper Lightspray manages to balance comfort with responsiveness, creating a ride that feels engaging rather than overly muted. The shoe performs particularly well during uptempo efforts and longer steady-state runs, where the geometry and propulsion become increasingly noticeable.
It’s the kind of shoe that subtly encourages momentum.
There’s a distinct rhythm to the way it runs – smooth, efficient, and surprisingly natural once the pace settles in. Rather than feeling gimmicky or overly engineered, the technology here largely serves the running experience itself.

Highly Specific
Of course, the Cloudmonster 3 Hyper Lightspray remains a highly specific shoe. The snug laceless construction may not suit every foot shape, and the aggressive geometry feels more at home during purposeful runs than slower recovery jogs.
But perhaps that’s part of its appeal.
This doesn’t feel like a shoe trying to cater to everyone. Instead, it feels like On fully embracing experimentation and performance innovation in a way that still feels wearable, exciting, and distinctly modern.
At a time when many super trainers are beginning to feel increasingly similar, the Cloudmonster 3 Hyper Lightspray stands out not simply because it looks different, but because it genuinely feels different too.
And in today’s performance footwear landscape, that’s becoming increasingly rare.
