On Cloud X: The versatile running shoe for cross-training

The On Cloud X is a true all-rounder in the running range. This shoe was developed for athletes who don't restrict their training to the track or pavement. It's a shoe that seamlessly transitions between running and functional workouts. Advanced technologies provide comfort, stability and explosive take-off. Whether you're picking up the pace on a run or challenging yourself with plyo exercises or core circuits, this shoe has you covered. Within the On collection, the Cloud X stands out as the most versatile model. Compact, lightweight and responsive, without compromising on support or durability.

The revolutionary CloudTec technology

The sole of the On Cloud X is made up of the signature CloudTec elements. These "clouds" are small, hollow pods that react independently to the impact of each step. They first absorb the shock and then convert that energy into a powerful take-off. The applied "Zero-Gravity" EVA compound enhances this effect. This lightweight foam layer provides cushioning without adding bulk. As a runner, you benefit from a direct, soft, yet responsive connection to the ground. Whether you're training for speed or strength, this technology supports your efficiency with every stride.

Speedboard for optimal energy return

Hidden between the midsole and the insole lies the Speedboard. This is a thin, flexible plate that bends on impact and then springs back to deliver a powerful push-off. The result is explosive energy return that supports both pace and technique. For runners, this leads to a more efficient running pattern. For cross-trainers, it offers extra support during multi-directional movements. The Speedboard stabilises the foot during landing and push-off, helping you maintain rhythm during tempo runs or lunges. Together with the CloudTec sole, it delivers a stable, smooth feel as you accelerate or decelerate.

Technical specifications of the On Cloud X

The On Cloud X combines lightweight design with technical refinement. Weighing around 230 grams for men and between 195 to 201 grams for women, this shoe is lighter than most all-round running shoes. The heel-to-toe drop is 6 mm, promoting a more natural gait and better control at toe-off. The wide platform and external heel counter help maintain balance and stability, especially during quick changes in direction. Thanks to the responsive cushioning, every contact with the ground feels surprisingly direct, without sacrificing comfort.

Superior fit and comfort

The fit of the On Cloud X is true to size and hugs the foot comfortably. The sculpted heel collar features soft foam padding that supports the ankle without getting in the way. The tongue is thin but lightly padded and prevents friction from the laces. All these details are designed with comfort in mind across a variety of workouts. This applies to easy miles as well as intense HIIT sessions. The shoe wraps naturally around your foot, without excessive pressure points or looseness. The result is a secure, stable fit that provides confidence with every step.

Breathable 3-layer mesh upper

The upper of the On Cloud X is made from technical 3-layer mesh. This construction keeps your feet cool, even during the most intense intervals. The top layer offers a breathable surface that quickly wicks away heat and moisture. The underlying layers provide structure and shape retention. The refined balance between flexibility and support makes this material ideal for various types of training. On top of that, it's built to last. So you can train outdoors or in the gym without worrying about premature wear and tear.

On Cloud X for various types of training

What makes the On Cloud X so popular among runners and athletes is its versatility. This shoe isn’t limited to one specific type of training, and you’ll notice that immediately. From tempo runs along the river to strength sessions in the gym, transitions feel effortless. The cushioning is responsive enough for explosive movements, yet also absorbs impact during longer runs. The design prevents wobbling during lateral steps, which is crucial during functional workouts. That’s why this model is ideal for athletes seeking variety without the hassle of switching shoes.

Ideal for interval training

During interval sessions, the lightweight and responsive nature of the On Cloud X truly shines. The low drop supports rapid acceleration. The CloudTec sole absorbs the impact of repeated sprints. The quick roll-through and short ground contact time help you move efficiently through your sets. Even as the intensity ramps up, the shoe keeps performing without feeling bulky. This makes it easier to stay in the flow during short, powerful efforts. The stability on landing and quick rebound at push-off make this shoe a reliable choice for progressive tempo work and fartlek sessions.

Suitable for gym and cross-training

The On Cloud X combines grip, stability and freedom of movement, all key features for gym performance. During circuits or strength workouts, the wide base provides solid footing for squats or lunges. The firm midsole keeps you standing upright without sinking in. At the same time, the shoe remains flexible enough to move smoothly during dynamic exercises. The upper fits snugly, helping to prevent sliding during side-to-side movements. This makes the Cloud X not just a valuable running shoe, but also a full-fledged training partner for the gym floor.

On Cloud X for different running styles

The On Cloud X is designed for athletes with a neutral stride, but offers enough adaptability for various techniques. For forefoot and midfoot strikers, the low drop supports a natural landing. The cushioning sufficiently absorbs impact for heel strikers who need a bit more support. Thanks to the well-thought-out outsole and distribution of cushioning elements, this shoe adjusts to your gait. There’s no need to immediately switch to a supportive or corrective model.

Stability for neutral runners

For runners with a neutral gait, the On Cloud X offers the ideal balance between structure and freedom. The shoe supports your stride where needed but doesn’t interfere with your natural movement. This allows for free and safe motion, whether you’re training for speed, endurance or technique. The sole and upper work together to keep your foot centred, without the shoe feeling overly controlling. It’s exactly this freedom that makes it a popular choice for athletes focusing on improving their technique.

On Cloud X vs. other On Running models

Within the On range, the Cloud X stands out as the most versatile model. Compared to the On Cloud, which is softer and geared more toward casual runs, the Cloud X offers greater stability and a firmer running experience for more intense workouts. The Cloudflow, on the other hand, is more focused on pure speed and racing. The Cloud X is more robustly built for cross-training, placing it right in between speed and support. This unique position makes it a great choice for athletes who combine different disciplines.

Colorways and design

The On Cloud X is not only technically impressive, but also visually appealing. With its sleek and modern design, the model fits the minimalist aesthetic that On is known for. The colorways update regularly, blending functional tones with fresh accents. There’s something to suit every style. Whether during your session, on the way to the gym or cooling down afterward, the shoe exudes quality. The colors complement the timeless silhouette, making it not just a performance-focused, but also a style-conscious choice.
