On Cloudswift Review 2019 – What the Helion?

The Cloudswift is something completely new from On, not only from an aesthetic standpoint, but also in how it feels and responds while running. Of course, none of this is by chance, On has been hard at work to innovate on an already innovative running shoe. This review is going to take a detailed look at every feature of the Cloudswift, how they perform while running and also how I think the shoes stack up against every other On running shoes currently available.

On Cloudswift Fit & Design

On Cloudswift Upper Construction

The Cloudswift running shoes wrap around my feet with a snug, comfortable fit. This is made possible by what On calls their ‘engineered-mesh sock’ which is designed to hug your foot for a precise and breathable fit. This feature is a first from On and allows a slip-on fit that’s even more comfortable than the popular On Cloud.

The upper mesh is extremely breathable too, which you’ll notice when running in hot weather. I recently took part in the Vi Trainer Virtual 5K; it was so hot out and I was pushing harder than I had in a long time, but my feet stayed cool throughout.

If you haven’t tried Vi Trainer before and you’d like to improve your running performance, then you should definitely check it out. In a nutshell, it’s an Artificially Intelligent Virtual Trainer that pushes you by training you in your headphones as you run. The voice actually sounds like a real person coaching you. It works using a heart rate sensor, GPS and past knowledge of your efforts, to know how hard you’re pushing. It learns more about you the more you use it and as a bonus, Vi sounds just like Scarlet Johansson, haha. Click HERE to start a free 14-day trial (cancel anytime). I’m so motivated to run more because of it and know you will be too. Try it! 🙂

The Cloudswift upper is made with a variety of materials, varying in tensile strength, stretch and support. Looking towards the mid-foot section of the upper you can see the mechanical side-band which gently supports your feet, it has a bit of stretch in it too. The holes that the laces loop through in the side-band also allow for a quick and easy lace fastening because the laces glide through it when pulled from the top, with little to no friction.

Something that you can’t really tell from the photos is that behind the side-band lies a hidden pocket, a place to stash your laces once tied up. This reduces lace flap and stops them from ever being able to untie themselves, It looks tidy too! You can see the pocket in my FIRST LOOK video above.

Padding around the heel area is soft and comfortable. The side walls don’t rise too high either, which give me more flexibility in the ankle/Achilles heel areas without unwanted rubbing. It’s generally a really comfortable fit that feels great right out the box, with absolutely no ‘breaking-in’ necessary.

Sizing Consistency

The Cloudswift fit is consistent with other On running shoes, which is also consistent with other popular brands including Salomon, Inov-8, and Merrell. They do feel ever so slightly roomier because of the one-piece construction, but the size is accurate.

Inner

The shoe slips on very easily and feels like your favorite slipper. There’s a neutral arch, which I love. This neutral feel is consistent with all other On shoes I have worn. I really like the lack of seams inside this new design too, there’s really nothing in there to rub on your feet or cause discomfort.

Midsole

There’s very good cushioning in the midsole, that makes these shoes excellent for long distance running, even marathons. When I’m running in them, I feel like I can just keep going because my feet stay feeling fresh and protected, the internal temperature regulation is so good that my feet don’t sweat either, which contributes to overall comfort.

Outsole – Made With Helion Superfoam

On Cloudswift review Trail Kale wm 7

It’s all about the Helion! On’s new superfoam, Helion provides a really lightweight, comfortable, and also responsive ride. It’s a very different feel to On’s that have come before, and I love that classic ‘running on clouds’ feeling. I think I prefer running on Helion even more though!

I can also feel that the outsole has a ‘rocker’ construction. This means that in its default state, the outsole curves up at the rear and the front. This in conjunction with On’s Speedboard, helps me to transfer my energy to forward momentum much faster than a shoe with a flatter sole. See image below for the rear rocker.

The tread provides very good grip, I know this as I had to dodge a few people at a moments notice, when they jumped out in front of me during my 5k virtual race. I changed direction in a split second with complete control.

Drop & Weight

There’s a drop of 7mm from heel to toe. It’s a happy medium for runners who like a minimal drop and others who prefer more. I’m a fan of keeping the drop as low as possible as it helps to improve my running form due to the more natural footfall. Many other road shoes will go as high as 10mm and beyond, a drop that high would be too much for me as I find it affects my form.

Weighing in at 290g the Cloudswift is a very lightweight running shoe, you’ll be able to run hard and far in a shoe this light.

Toe Box

On Cloudswift review Trail Kale wm 10The toe box is a medium width and feels nice and airy due to the breathable upper material.

In Summary

The Cloudswift is something very new from On, not only does it look unlike any other On’s it also has a different feel to it while running. If you’ve ‘run on clouds’ before, then you won’t be disappointed with the Cloudswift, On’s latest lightweight running shoe.

The shoe fits very comfortably and feels just as comfortable while running, even after many miles. The breathable upper keeps the temperature of your feet nicely regulated, on the hottest of days.

Then there’s the new superfoam, Helion! This cushioned material makes running on asphalt a breeze because of its surprisingly good energy transfer when combined with the rocker outsole design, and the strong speedboard that supports it.

The On Cloudswift is now my go-to road running shoe for speedwork and racking up weekly road miles. As a result, it has also toppled the On Cloud X from the top spot of my ‘Best On Shoes Ranked and Reviewed‘ post.
