Description

The lightest daily trainer On make, and the one built around CloudTec Phase - a pod geometry computer-optimised to collapse in sequence from heel to toe rather than all at once. The result is a roll rather than a landing.

Helion foam tuned for softness sits under it, and the mesh upper is kept deliberately plain: embroidered eyelets, a reworked tongue, nothing that adds weight. At 225 g it is the shoe you stop noticing.

Two of On's four listed activities.
Features
  • CloudTec Phase. A newer pod geometry, computer-optimised so the pods collapse in sequence from heel to toe instead of together. You feel it as a continuous roll through the footstrike rather than a distinct landing and push-off.
  • Helion foam tuned for softness. The same Helion foam On use across the range, tuned here toward softness rather than support or return. It is what keeps a light shoe from feeling thin.
  • Breathable mesh upper. Engineered to optimise breathability, with embroidered eyelets and overlays instead of stitched-on ones - lighter, and one less thing to rub.
  • Updated tongue construction. Reworked on this version for a more comfortable fit. A small change, but the tongue is where a light upper usually starts to annoy you.
  • Durable outsole and updated tread. More rubber and a reworked tread pattern. The obvious weak point of a 225 g shoe is that it wears out, and this is where On addressed it.

Performance

How it ranks across conditions.

Calibrated against comparable products we stock, so you can compare like for like.

Cushioning

Firm
Moderate
Plush
Max

On rate cushioning Medium. Enough for daily miles, deliberately short of max-cushion - that is what keeps it at 225 g.

Stability

Neutral
Light support
Structured

On rate stability Medium-High, which is high for a shoe they classify as Neutral. The Phase pod geometry does that - a sequenced collapse is inherently steadier.

Responsiveness

Cushioned
Balanced
Propulsive

On rate it Low-Medium. There is no plate, but the rolling geometry and the light weight make it feel more willing than the number suggests.

Weight

Light
Moderate
Substantial

225 g in a women's sample size - the lightest daily trainer in On's range and the main reason to choose it.

Best for

Is this right for you?

Everyday training runs

The default daily trainer if you want to feel light. Enough cushioning for the miles, a rolling geometry that makes the pace feel easier, and little enough weight that you forget it is there.

Not for: Not a max-cushion shoe. If you want deep protection for long or slow runs, the Cloudsurfer Max or the Cloudstratus 3 are the same idea with far more foam. Shop road running shoes

Runners who dislike heavy shoes

If cushioned trainers usually feel like too much shoe, this is the one that does not. At 225 g with a 9 mm drop it sits closer to a traditional trainer than most of the current cushioned crop.

Not for: The 9 mm drop is the highest in this group - if you prefer a low drop, look at the Cloudsurfer Max at 6 mm. Shop women's shoes

Walking and treadmill

On list both alongside road running. The rolling geometry suits walking pace and there is enough rubber for a belt.

Not for: Not for trails - a road outsole with no lugs. Shop all footwear

Questions, answered

Before you buy.

Pulled from chats, emails and store visits. The things people actually ask us before they buy. Don't see yours?

Ask a question
What is CloudTec Phase and how is it different from regular CloudTec?

Both are On's pod-based cushioning, but Phase changes when the pods compress. On standard CloudTec the pods under your foot compress broadly together. On CloudTec Phase the geometry is computer-optimised so they collapse in sequence, heel through to toe, following your footstrike. You feel it as a continuous roll rather than a distinct landing and push-off. It also tends to feel steadier, which is why On rate this shoe Medium-High for stability despite calling it neutral.

How is the Cloudsurfer 2 different from the Cloudsurfer Max?

Same family, different amount of shoe. The Cloudsurfer 2 has one layer of CloudTec Phase, weighs 225 g and has a 9 mm drop. The Cloudsurfer Max has two layers, weighs 262 g and drops to 6 mm, and On rate its cushioning High against the 2's Medium. Choose the 2 if you want light and lively for daily miles; choose the Max if you want protection for longer or slower runs. Both are neutral and both roll rather than land.

Is 225 g too light to be cushioned enough?

No, but it is a genuine trade and worth understanding. On rate the cushioning Medium - comfortable for daily mileage, well short of a max-cushion shoe. What you get back is a shoe that disappears on your foot, which for a lot of runners matters more over an hour than another few millimetres of foam. If you regularly run beyond about 90 minutes, or you finish runs with sore joints, size up the cushioning rather than the shoe and look at the Max or the Cloudstratus.

Does it fit true to size?

Take your usual running size. The mesh upper is engineered for breathability and has a little natural give, and the tongue construction was updated on this version for a more comfortable fit. The embroidered eyelets and overlays sit flat rather than being stitched on, so there is less bulk across the instep than on many uppers. It is stocked here in one fitting.

What changed from the first Cloudsurfer?

The outsole and the upper, mostly. On updated the tread pattern and made the outsole more durable, which was the main complaint about the original - a light shoe that wore through quickly. The tongue construction was reworked for comfort, and the eyelets and overlays are now embroidered rather than applied. The CloudTec Phase geometry and the Helion foam that define the ride are carried over, so it still runs like a Cloudsurfer.
