The Grivet Take
The Cloudrunner 2 is On's dedicated stability daily trainer with a cradle-shaped construction that holds the foot securely without forcing correction. The new Helion superfoam midsole delivers more energy return than the original Cloudrunner; the 10mm drop runs traditional and pairs well with heel-strikers. The 30mm heel stack provides moderate cushion suited to daily mileage. This is an option for runners who want On's CloudTec aesthetic with gentle stability features. Cross-shop with Brooks Adrenaline GTS 25 for the most familiar moderate-stability daily trainer and Saucony Guide 18 for a wider-platform stability ride.

Support
Support TypeSupport Type describes how much built-in guidance the shoe has. Neutral shoes do not add support structure. Stability shoes use geometry, rails, firmer foam, or frame designs to create a more guided feel. Motion control shoes are the maximum-support category and are rare in modern running.

How it fits
Fits true to size for most runners. Toe box runs standard width with normal vertical volume. The cradle-shape construction wraps the midfoot securely for stability; the plush tongue and durable heel clip lock in heel hold. Available in standard (D) only at Grivet for women's.
How it feels
Cushion is moderate at 30mm heel stack. The new Helion superfoam delivers more energy return than the original Cloudrunner's standard EVA; the ride is softer with more pop. The 10mm drop encourages a heel-strike pattern and reduces calf and Achilles loading. The cradle-shape construction adds stability through geometry rather than a medial post; runners with neutral mechanics will hardly notice the support working. The platform is wide for stable footfalls; the ride is smooth and predictable across daily-mileage paces.

Tech, translated
Helion superfoam is On's named premium midsole foam, lighter and more responsive than standard EVA. The Cloudrunner 2 is upgraded to Helion from the original's standard foam; the change adds energy return without firming the underfoot feel.
The cradle-shape construction is On's stability approach: the midsole is shaped to cup the foot rather than using a medial post or guide rails. The result is gentler than older posted designs; stability comes from the platform geometry.
The outsole uses rubber on the high-wear areas with an upgraded pattern that does not trap stones. The 10mm drop is on the higher end of modern running shoes and shifts loading away from the calves and Achilles.
Frequently asked
Does the On Cloudrunner 2 run true to size?
The Cloudrunner 2 runs true to size for most runners. The toe box is standard width with normal vertical volume; the cradle-shape construction wraps the midfoot securely. Available in standard (D) only at Grivet for women's. Runners between sizes can usually stay with their typical On size.
Is the On Cloudrunner 2 firm or soft underfoot?
The Cloudrunner 2 is balanced. The new Helion superfoam delivers softer landings than the original Cloudrunner; the cradle-shape construction adds stability without firming the foam. Runners who want a softer stability shoe should look at the Hoka Arahi 8 instead.
Is the On Cloudrunner 2 good for treadmill running?
Yes. The rubber outsole grips treadmill belts reliably and the moderate cushion absorbs the harder treadmill landing well. The 10mm drop encourages a heel-strike pattern that is comfortable across longer treadmill sessions. The cradle-shape construction maintains foot position confidently across extended treadmill efforts.
How does the On Cloudrunner 2 compare to the Brooks Adrenaline GTS 25?
Both are moderate-stability daily trainers with traditional drops. The Cloudrunner 2 has the On CloudTec aesthetic and a cradle-shape stability construction; the Adrenaline GTS 25 uses GuideRails along the heel and has a wider width selection at Grivet. Pick the Cloudrunner 2 if you have run in On before or want the On look; pick the Adrenaline if you need wide widths or prefer Brooks fit.
Is the Cloudrunner 2 good for new runners?
Yes. The 10mm drop, moderate cushion, and gentle stability through the cradle-shape construction make the Cloudrunner 2 approachable for new runners. The plush tongue and easy step-in upper add comfort for runners learning to enjoy daily training. The On look and feel are familiar to new runners coming from On lifestyle shoes.
What is the difference between the Cloudrunner 2 and the original Cloudrunner?
The Cloudrunner 2 upgrades to Helion superfoam from the original's standard EVA midsole; the change adds energy return and softens the ride. The upper is also refined for better lockdown. Both share the cradle-shape stability construction and 10mm drop character; the v2 is the more polished version.
