A fast-feeling running shoe designed for runners of all abilities, the On Cloudflow 4 adds fun to any run.

You’ll no longer feel like you’re slogging through your runs with this lightweight and responsive trainer. The engineered woven upper is lightweight and hugs the foot in all the right places. The midsole – composed up a dual-density of On’s Helion foam and a new nylon Speedboard – is tuned for snappy and effortless transitions. Running’s supposed to be fun, and the On Cloudflow 4 is an undoubtedly fun running shoe.

WHY PACERS CARRIES THESE SHOES:

Some runners might be fine with having a different shoe for every distance and pace that they could possibly run on a given day. The rest of us don’t have walk-in closets in every room.

Fortunately, there are running shoes out there for people like us.

While the On Cloudflow 4 best lives up to its design at a moderate, 10k- to half-marathon pace, it has 31 mm of dual-density Helion foam that provides the required cushion for an workhorse everyday trainer.

And, at the other end of the speed spectrum, it can serve in a pinch for paces as well.

From the moment you put it on, the Cloudflow 4 feels fast, starting with the incredibly airy engineered woven upper. The revamped nylon Speedboard is spoon-shaped to work with your body’s natural momentum for a smooth, speedy feel whether you’re blasting 400m repeats, warming up for your workout, or hitting the roads for a long run.

WHAT’S NEW:

Like the Cloudflow 3, the Cloudflow 4 is a lightweight, responsive, and fast road running shoe that works just as well as an everyday trainer as it does as an all-around workout shoe.

The Cloudflow 4, however, comes in a sleeker, more modern, and – dare we say? – sexier package.

A beautiful engineered woven upper just looks clean and fast. This shoe comes with dual-density Helion foam, adding 8 mm of softer cushion underneath the foot. On’s plastic Speedboard is reworked into a spoon-shaped nylon Speedboard that better works with the body’s natural momentum.

The result is a versatile and speedy running shoe for all distances.
