If you’re a runner who prioritizes comfort and protection on every mile, the ON Cloudace might just be the shoe you’ve been waiting for. Designed as ON’s plushest running shoe, the Cloudace promises to deliver maximum cushioning without sacrificing the brand’s signature lightweight feel and responsiveness.
But what makes the Cloudace truly stand out? And is it the right shoe for your running style and goals? In this in-depth review, we’ll explore the Cloudace from every angle — its design, technology, fit, performance, pros and cons, and how it compares to other cushioned shoes on the market.

First Impressions: A Cushioning Powerhouse Wrapped in Sleek Design
Right out of the box, the ON Cloudace impresses with its bold, modern look. It’s noticeably larger and more substantial than ON’s lighter models, but still sleek and stylish enough that many runners say they love wearing them casually, too.
The upper is crafted from breathable engineered mesh, designed to offer support without suffocating your feet. The midsole and outsole stand out with thick CloudTec® pods that promise to absorb even the hardest impacts.
For runners who want to feel like they’re running “on clouds,” the Cloudace sets the bar high.
The Tech Breakdown: What Powers the Cloudace Cushioning?
1. Dual-Layer CloudTec® Outsole
The Cloudace features ON’s patented CloudTec® technology — but with a twist. Instead of a single layer of clouds, the Cloudace boasts double layers of cushioning pods. The first layer absorbs impact, while the second adds an extra buffer of softness and protection.
This dual-layer design is one of the thickest and most cushioned ON shoes to date, engineered to deliver a plush landing on every step.
2. Helion™ Superfoam Midsole
Beneath the clouds sits ON’s Helion™ superfoam midsole. This foam is specially formulated to remain durable and responsive in all weather conditions, offering a perfect blend of softness and energy return.
Whether you’re running on hot asphalt or chilly concrete, Helion™ foam helps keep your stride smooth and efficient.
3. Speedboard™ for Propulsion
Inside the midsole is ON’s famous Speedboard™ — a flexible plate that supports your foot’s natural rolling motion and adds spring to your step. The Cloudace’s Speedboard™ works seamlessly with the thick cushioning to keep you moving forward without feeling sluggish.
4. Engineered Mesh Upper
The upper combines soft, breathable mesh with targeted reinforcements around the heel and midfoot for added support. This keeps your foot secure without sacrificing comfort or airflow.
How Does the ON Cloudace Perform? My Running Experience
Cushioning: Plush Yet Responsive
If you’re coming from minimal or moderate cushioning, the Cloudace feels like a revelation. Each step feels like landing on a fluffy cloud, with impact absorbed so effectively that even pounding city streets feels gentle.
Surprisingly, despite the generous cushioning, the shoe doesn’t feel mushy or slow. The Helion™ foam and Speedboard™ inject enough responsiveness to keep your stride lively.
Comfort and Fit
The fit is generous but supportive. The upper hugs your foot like a soft glove, and the padded tongue and collar add to overall comfort. The heel cup locks the foot in place firmly, which helps prevent slippage on longer runs.
Who Should Consider the ON Cloudace?
- Long-distance runners: Especially those logging serious miles who want maximum protection from impact.
- Runners with joint concerns: The thick cushioning helps reduce stress on knees, hips, and ankles.
- People who love plush comfort: If you prefer a soft, cushy ride over minimalism or racing flats.
