Introducing the new On Cloudswift featuring Helion, an active superfoam that is a lighter, softer, and more agile foam so you feel more alive every step of the run




Are you ready to 'Helion' your run?

Introducing the On Cloudswift, the new style from On Running. A brand new running shoe featuring On's proprietary new Helion foam technology allowing a lighter, softer and more explosive run. 

If you’re a runner who likes to have one reliable shoe in your quiver, the new Cloudswift is an ideal choice.

Guest JackRabbit reviewer, Brian Metzler took the brand new On Cloudswift out for some runs with his gear reviewers, putting this brand new running shoe through its paces on long runs, speedworks and some fartlek training.

Read on to learn what they thought.


The On Cloudswift is a brand new everyday training shoe built on an innovative foam that offers optimal resiliency and energy return.

It serves up a comfortable fit and feel and a smooth, consistent and very energetic ride that’s ideal for easy runs, speed workouts and long runs.


On Running’s new Helion foam is a new compound made from hard and soft materials that offers amazing shock absorption and energy return properties while also providing durability and protection from the road.

To maximize the efficacy of the Helion foam, On created new shapes of its Cloud Elements cushioning pods so that they track diagonally and increase the horizontal cushioning. 

The new On Cloudswift remains super light because rubber is only featured in high-abrasion areas of the outsole, providing just enough grip and durability in wet conditions and rough roads.  This reduces weight but has the wear and tear support in just the right places. 

The new On Cloudswift features the firm plastic “Speedboard” that works like a propulsion agent, helping maximize the energy return as a foot rolls through the cycle of a stride. Although you can barely see it — it’s only exposed between the Cloud Elements in the rear of the foot — you know it’s there because every new stride begins with a boost of energy.

Right out of the box, the fit of the On Cloudswift is snug and secure, wrapping the foot thanks to the sock-like upper and the soft, wide, flexible external saddle support bands that integrate to the laces.

The forefoot provides plenty of room for the toes to wiggle and splay as the traverse arch of the foot flexes at the toe-off phase of a stride.

Once laced up and dialed in, the Cloudswift feels like it’s part of your foot, promoting enhanced agility and natural flexibility on the run. It’s not a soft shoe or a firm shoe, but instead the perfect blend in between, serving up the great mix of comfort and performance.

Thanks to a wide platform, rockered (or convex) profile, plenty of cushioning and a firm plastic “Speedboard” that runs from heel to toe above the midsole, the ride you experience in the On Cloudswift is smooth, stable and electric from touch-down to toe-off.


What type of runner will match with this new style from On Running? Without a doubt, runners who appreciate lightweight and versatile running shoes will be drawn to trying this new style. Especially those runners who also appreciate modern design will love this shoe.  

On Running is a leader at the forefront of the modern running movement taking high-level style with performance technology. The distinctively clean aesthetics and functional design of the On Cloudswift make this running show a modern marvel.

It looks great, it feels great, it runs great.


On Cloudswift - Pros

Pros:On Cloudswift

The On Cloudswift is one of those running shoes that feels and runs lighter than the advertised weight. While we concur that it the spec weights are accurate, the airy design of the midsole makes it feel lighter and more nimble on the run.

On calls theHelion material a “superfoam that doesn’t tire” and we tend to agree. We took the Cloudswift out for a 10-mile road run and found it to be just as energetic in the last mile as it was in the first. 

We loved the Cloudswift’s versatility. We took it on long runs, short recovery runs and also did two speedier sessions—a 5-mile tempo run and a fartlek interval workout that included 2 minutes of race pace running and 2 minutes of jogging.

On Cloudswift - Cons

Cons: On Cloudswift

It took a few tries to find the right tension in the laces, partially because the two eyelets over the vamp tightened up independently from the four eyelets in the saddle support bands.

But once this is dialed in, this was not an issue, just remember to take some time to get the lacing right when you first lace up.
