The Swiss-engineered brand On Running, often simply called “On Cloud Shoe” has skyrocketed in popularity, recognizable by its distinctive, perforated CloudTec® outsoles.1 These unique “cloud” elements are designed to offer cushioned landings and explosive take-offs.2 However, with a rapidly expanding lineup that spans from lifestyle sneakers to dedicated racing flats, navigating the brand’s offerings can feel like being lost in the fog. This comprehensive comparison chart and guide breaks down the most popular On Cloud models across various categories, helping you find the perfect pair for your specific activity and needs.

On Cloud’s Core Technology: What Sets Them Apart
Before diving into specific models, understanding On’s proprietary technologies is key to deciphering the differences between them:
- CloudTec®: This is the core technology—the visible “cloud” pods on the outsole.3 They compress horizontally and vertically upon landing, providing cushioning, then lock into a firm base for a powerful push-off.4
- Speedboard®: A liquid-injected plate situated between the midsole and the upper.5 It stabilizes the foot and is designed to turn the energy from the landing into forward momentum for the take-off. The stiffness and shape of the Speedboard vary significantly by model, dictating the shoe’s responsiveness.
- Helion™ Superfoam: A highly responsive and durable foam used in many midsoles.6 It’s designed to be lightweight, yet offers cushioning that performs well across a wide range of temperatures.
- CloudTec Phase™: An evolution of CloudTec, this cushioning is computer-optimized for a smoother, softer ride.7 The ‘Clouds’ seamlessly collapse like dominoes as your foot lands, offering a fluid transition from heel to toe, often found in models that prioritize soft comfort.8
- Missiongrip™: On’s special rubber compound designed for trail running. It provides enhanced traction and grip on varied and slippery surfaces.9

Deep Dive: Comparing the Key Categories
1. The Everyday and Lifestyle Collection: Comfort First
For many, an On Cloud shoe is an all-day comfort or travel shoe, not a running tool.10 This category focuses on ease of wear, style, and simple, consistent comfort.
On Cloud 6 (The Icon)
The Cloud 6 is the quintessential “Cloud” shoe. It’s recognizable, lightweight, and incredibly easy to slip on and off thanks to its trademark speed lacing system.11 Its cushioning is relatively low compared to performance models, but it’s perfect for commuting, city walking, or light errands. The ride is firm and quick, making it a favorite for those who value speed and style in their daily activities.
On Cloudtilt (The Walker)
The Cloudtilt is a newer model specifically geared toward the high-mileage walker or traveler.12 It utilizes the CloudTec Phase™ technology, which offers a softer, rolling sensation rather than the snappier, firmer feel of the traditional Cloud.13 It prioritizes comfort over explosive speed, making it an excellent choice for standing all day or touring a new city.
2. Daily Training and Max Cushion: Logging the Miles 🏃♀️
This is the core of On’s road running lineup, where shoes are designed for durability, comfort, and performance across a runner’s weekly mileage.
On Cloudsurfer Max (The Smooth Operator)
The Cloudsurfer Max is all about maximum comfort and a fluid transition.14 Its use of CloudTec Phase™ eliminates the traditional Speedboard for a more natural, incredibly soft feel.15 This makes it ideal for easy, long runs or recovery days where you just want to cruise and prioritize impact absorption. It’s often recommended as the best all-around On model for runners seeking a highly cushioned, less aggressive ride.
On Cloudmonster (The Bouncy Beast)
As the name suggests, the Cloudmonster is built with the largest Cloud elements in On’s line, providing a massive stack of cushioning.16 This model delivers a highly bouncy and energetic ride, feeling significantly more cushioned and propulsive than other daily trainers. It’s perfect for runners seeking a high-cushion option for high-mileage training and long efforts where energy return is a priority.17
On Cloudrunner (The Stable Choice)
While most On shoes are neutral, the Cloudrunner is designed for those who require a bit more stability to counter overpronation.18 It achieves this with a wider base and strategically placed supportive elements, offering a reassuringly stable platform without feeling intrusive. This is a top pick for beginners or those who need gentle guidance on their daily miles.
3. Speed, Racing, and Agility: Going for the Win 🥇
These models strip away weight and often incorporate advanced components like carbon fiber plates to maximize speed and responsiveness.
On Cloud X 4 (The Gym Workhorse)
The Cloud X 4 is the versatile trainer designed for mixed-activity workouts.19 It’s lightweight, agile, and has excellent lateral support, making it perfect for gym sessions, HIIT classes, plyometrics, and shorter, faster runs. Its multi-directional grip and responsive feel make it a true cross-training specialist.
On Cloudboom Max (The Marathon Racer)
When the clock is ticking, the Cloudboom Max steps in. This is On’s top-tier race day shoe, featuring a curved carbon-fiber-infused Speedboard sandwiched between layers of responsive Helion™ foam. It’s ultra-lightweight and offers maximum energy return, designed to shave seconds off your personal best in half-marathons and full marathons. This model sacrifices some durability and all-day comfort for pure, uncompromising speed.
4. Trail and Outdoors: Off-Road Adventures 🏞️
For those who venture off the pavement, On equips its outdoor line with specialized traction.20
On Cloudultra (The Long Trail Runner)
The Cloudultra is the go-to for long-distance trail running.21 It features dual layers of CloudTec and a Missiongrip™ outsole with deeper lugs, providing superior grip and protection on technical and variable terrain. It’s built for comfort over multi-hour efforts, offering a balance of cushion and ground feel necessary for navigating rocks, roots, and mud. The unique FlipRelease™ lacing tool allows for easy mid-run adjustments to relieve pressure on swollen feet.
Making Your Final Decision
Choosing the right On Cloud shoe boils down to a single question: What is its primary purpose?
- For maximum daily comfort and walking: Choose the Cloud 6 (for classic style and easy on/off) or the Cloudtilt (for a softer, more modern ride).

- For stability on the road: Choose the Cloudrunner.
- For versatile gym/road use: Choose the Cloud X 4.
- For racing and speed: Choose the Cloudboom Max.
