Shoe Review: On Cloudswift 2021


The second edition of the On Cloudswift has gone through some significant changes, but it remains a lightweight, low-profile neutral trainer with a cushy, energetic vibe.

It features On’s updated CloudTec midsole cushioning technology, which offers a blend of reliable shock absorption, protection, durability and a lively feel.

Aside from the slightly reconfigured midsole, other updates to the On Cloudswift include increased rocker geometry, enhanced forefoot cushioning and a re-engineered Speedboard for a more flowy ride and snappier feeling at toe-off.

The innovative CloudTec cushioning system is the key feature of the On Cloudswift. It’s been slightly updated with a bit more Helion foam cushioning that’s been formed into more of a rocker shape. The foam chassis is slightly thicker and cushier in the rear, but it’s snappier and more energetic in the forefoot.

The Cloudswift retains its unique one-piece upper that combines the practicalities of a fully gusseted tongue with an overarching upper with a wrap-like fit. The updated saddle sidewall panels are more supportive and more comfortable as they encase your foot.

It also has a new 100 percent recycled mesh upper with more supportive sidewall panels.

The revised On Cloudswift fits true to size, but it has more of a medium- to low-volume interior with just a tiny amount of wiggle room for the toes. It’s not cramped, but it’s not wide, either. When you first step into the shoe and lace it up, it feels comfortable, secure and semi-soft.

The new upper configuration is slightly less pliable than the previous edition. The upper, combined with the new, slightly sturdier sidewall saddle supports makes for a more locked-down fit sensation.

The ride gives off soft, shock-absorbing and supportive vibes with a more distinct rolling sensation than in the past. This is generated by the new, shapelier incarnation of the Helion superfoam and rubber outsole pads.


Runners who appreciate neutral-oriented shoes with a moderate to high cushion-to-weight ratio will love this shoe. It’s light and agile enough to be versatile to handle a variety of workouts. It's also cushioned enough to be durable and comfortable for long runs.

If you only want one shoe in your quiver, it’s a good one to consider.

The new engineered mesh material in the upper is made from 100 percent recycled polyester, nylon and TPU materials. The upper is better integrated with the lacing system, creating better foot hold and an improved all-encompassing fit.

The cushioning in the ankle collar liner has been reduced and the heel counter band is slightly less rigid. These features actually make the shoe closure sync up more consistently.

This shoe feels moderately light when you put it on, but feels even lighter when you run in it. It is also, well-balanced with a lively feel in the midsole/outsole undercarriage.

If you previously ran in the On Cloudswift, you’ll find this new version a tiny bit softer and smoother. The new version features small but noticeable bits of improved comfort.

There are no glaring drawbacks to the Cloudswift. It’s probably not the best shoe for running shorter, faster workouts on the track, but it can hold its own on tempo runs, fartlek runs and slow to moderately fast long runs.
