Shoe Review: On Cloudflyer

A photo of the On Cloudflyer

The On Cloudflyer provides formidable support and cushion that holds up mile after mile.

The latest edition of the Cloudflyer employs large, stable CloudTec elements, while Helion foam makes the shoe light and energetic. Designers created an accommodating shoe with a generous midfoot and comfortable toe box, and they used different zones of mesh to improve the fit.

With a plush step-in feel and sleek, minimalist design, the On Cloudflyer is capable of handling just about every pace you can throw at it. Fleet Feet reviewers put some miles on the On Cloudflyer to see how it fits and how it performs. Here’s what they thought.

On Cloudflyer Fit and Materials

The mesh upper of the On Cloudflyer

Like all On running shoes, the Cloudflyer sports a sleek, minimalist design and quality construction with On’s signature CloudTec midsole.

A zoned mesh upper creates different characteristics across the top of the shoe, and an accommodating toe box meets a secure midfoot and heel. Here’s what you need to know about the Cloudflyer’s fit:

Upper Design

Designers covered the Cloudflyer in a cushioned engineered mesh upper that’s comfortable and flexible.

Plus, different zones of mesh across the upper enhance flexibility further along with an open-patterned mesh on the toe box to vent heat. A tighter weave wraps the midfoot for added structure.

Even though the mesh changes from the forefoot to the midfoot, the inside of the shoe is soft and smooth. A cushy internal bootie lines the inside of the shoe, which adds a little bit of plushness throughout.

“It’s also roomy,” says one tester. “I was pleasantly surprised with the space in the forefoot. That combined with a locked-down midfoot, really provides an all-around great fit.”

A padded tongue sewed into the bootie helps keep debris out and adds a cushioned feel. From the moment you step in, the Cloudflyer feels built for comfort.

Heel Fit

On designed the heel of the Cloudflyer with good structure.

An external heel counter wraps around the back of the shoe to create a rigid heel cup, and it blends cleanly into the overall design of the shoe—the heel counter creates a clean line with the two-tone midsole.

Using a rigid heel counter helps create a locked-in fit. On also included an extra lace hole at the top of the shoe to let you use marathon lacing (also called heel-lock lacing) if you have a narrow heel or experience any slipping, but one tester says he didn’t have any problem with the heel fit.

“The heel feels pretty good to me as is,” he says. “But I actually re-laced the shoes using the heel-lock lacing, and it felt super secure without making the rest of the shoe too tight.”

Overall Fit

The Cloudflyer has an accommodating fit from heel to toe, which makes it comfortable for longer runs.

Reviewers say the midfoot has plenty of width, and the tight mesh weave provides good structure to really lock down the laces. Like the midfoot, the toe box is also roomy. There’s enough space to let your feet relax naturally, and the looser mesh pattern stretches to conform to the unique shape of your foot.

One reviewer says she noticed the fit immediately.

"The Cloudflyer is instantly comfortable," she says. "It’s roomy, it's easy to lace, and it stays tied."

The length feels true to size.

On Cloudflyer Ride and Performance

On built the Cloudflyer to give you consistent support and premium cushioning, so designers powered it with Helion foam, finely tuned Cloud elements and On’s signature Speedboard.

Helion foam is a lightweight cushioning that gives you solid impact protection without feeling cumbersome. The foam feels protective when you land but firm when you take off—there’s no mushy feeling.

The foam is shaped into the CloudTec elements that are a staple of On shoes, but the elements beneath the Cloudflyer are designed for better support. There are fewer individual elements underneath the Cloudflyer than in a speed-focused shoe like the On Cloudflow, and each element is wider. The wider elements create a stable transition that’s as good for new runners as it is for marathon veterans.

Reviewers like the soft, stable feeling created by the expanded Cloud elements.

“The Cloudflyer feels like a great all-around shoe,” one reviewer says. “It feels cushioned enough to be comfortable on pavement for long runs and light enough for a quick workout.”

On also layered its signature Speedboard into the Cloudflyer. The Speedboard is designed to support the natural rolling motion of your foot by loading with energy when you land and releasing it when you take off.

The Speedboard gives the Cloudflyer a snappier feel and enhances the responsive ride created by the Helion foam.

The Bottom Line

On Cloudflyer Heel

The updated On Cloudflyer is a well-rounded performer that gives you versatility for your training.

On engineered the Cloudflyer with Helion foam for a light ride that protects you from the pavement, and they capped it with a dynamic mesh upper for stretch in the toe box and support in the midfoot.

On’s unique CloudTec technology underfoot creates a stable transition and gives the shoe a supportive feel.

"The Cloudflyer feels luxurious for an easy, recovery run thanks to the thick cushion, but it's also bouncy enough for some medium-paced and uptempo runs," a reviewer says.

Whether you’re a new runner progressing quickly through training or you’re an experienced racer with a PR on the line, the On Cloudflyer is a capable and versatile trainer partner.
