Designed for Multidirectional Movement

The Cloud X 4 uses an X-shaped Speedboard® engineered to improve forefoot flexibility during training movements that occur in multiple directions.

Forefoot Flexibility

The X-shaped geometry allows the front of the shoe to move more naturally during lateral transitions, jumps and dynamic exercises.

Power & Control

From burpees and box jumps to circuit training, the Speedboard® works with the cushioning platform to provide responsive movement without excessive rigidity.

Versatile Training Focus

Cloud X 4 is designed to perform across a wide variety of workouts rather than specializing only in straight-line running.

Soft Landings

Helion™ superfoam helps reduce harsh impact during jumps, repeated movements and active training sessions.

Powerful Take-Offs

The foam responds as weight shifts forward, supporting energetic transitions into the next movement.

Training Stability

The cushioning is optimized for training, balancing energy return with the stability required for multidirectional exercise.

Bio-Attributed Foam

The original Cloud X 4 platform uses bio-attributed Helion™ foam, developed through a certified mass-balance approach that replaces part of the conventional fossil-based EVA content with renewable feedstock.

Midfoot Cage

A structured cage wraps around the middle of the foot to improve support and create a secure connection between the upper and platform.

Lateral Stability

Additional midfoot support is especially useful during lateral lunges, circuit exercises and movements that generate force across the shoe.

Star Lacing

The star-lacing configuration works with the midfoot cage to provide additional lockdown and support.

Secure Heel Hold

Enhanced heel construction helps reduce unwanted rearfoot movement during rapid changes of direction.

Light Stability

The shoe provides a supportive foundation while maintaining enough flexibility for dynamic and varied workouts.

Lightweight Polyester Construction

The upper uses polyester mesh to create a lightweight technical structure suitable for active training.

Airflow

Breathable mesh zones promote ventilation during higher-intensity sessions and warmer conditions.

Plush Heel & Tongue

Soft materials around the heel and tongue improve comfort at common pressure and contact points.

Technical Appearance

Visible woven texture gives the Navy / Gourami colorway a sophisticated performance-driven finish.

Official Navy / Gourami Reference

Style 3ME30044739 is officially identified as the men's Cloud X 4 in Navy / Gourami.

Deep Navy Upper

The textile upper uses a dark navy tone that can appear almost charcoal or black in lower lighting.

Gourami Blue Accents

Bright blue detailing at the heel and outsole introduces a controlled technical contrast.

Grey On Branding

Silver-grey branding provides visual separation from the dark upper while maintaining a refined look.

Dark CloudTec® Platform

The dark cushioning platform continues the technical aesthetic through the lower portion of the shoe.

Versatile Dark Palette

Navy and charcoal tones pair naturally with black, grey, white, blue denim and technical outerwear.

HIIT

Flexible forefoot movement, responsive cushioning and lateral support make Cloud X 4 suitable for mixed high-intensity workouts.

Gym Circuits

Cloud X 4 can transition between multiple training movements without feeling overly specialized for a single activity.

Burpees & Box Jumps

The X-shaped Speedboard® is particularly relevant for explosive exercises requiring flexibility, bounce and control.

Functional Training

Midfoot support, star lacing and rubber traction support dynamic movements and rapid changes of direction.

Calisthenics

The combination of light stability and forefoot flexibility makes the shoe suitable for many bodyweight-focused sessions.

Treadmill Training

The cushioning platform can also handle treadmill running when included within mixed gym workouts.

Everyday Wear

The Navy / Gourami colorway is understated enough for commuting, errands, travel and everyday athleisure styling.

On officially describes the men's Cloud X 4 as true to size.

Customers with normal-width feet can generally start with their usual men's On footwear size.

Foot width, instep height, sock thickness and preferred toe room can still affect the most comfortable choice.

The photographed product box is marked US Men's 7 / EU 40 / UK 6.5 / JP 25. These values correspond with On's men's size chart for EU 40.

Navy Monochrome

Navy trousers, shorts or technical outerwear create a clean tonal outfit around the dark upper.

Black Technical Styling

Black cargos, performance shorts or relaxed trousers work naturally with the charcoal-navy base.

Grey & Charcoal

Grey clothing connects easily with the dark midsole and silver-grey On branding.

Blue Denim

Washed or dark indigo denim complements the Gourami blue accents without making the outfit overly athletic.

White Contrast

White tees, training tops or lightweight jackets create a clean contrast against the dark footwear.

Technical Streetwear

Utility trousers, performance shells, technical bags and functional outerwear emphasize the engineered look of the shoe.

Athleisure

Training shorts, tapered pants and performance basics create an easy gym-to-street combination.

Remove Loose Dirt First

Use a clean soft brush to remove dry dust and surface debris before applying water or footwear cleaner.

Clean Mesh Gently

Use a soft cloth or soft-bristle brush with diluted mild cleaner. Avoid aggressive scrubbing that may damage the textile surface.

Protect Printed Branding

Clean carefully around On logos, Swiss Engineering details and other surface graphics rather than repeatedly brushing across them.

Clean the Cloud Cavities

Dust and debris can collect around the hollow CloudTec® structures. Use a small soft brush rather than sharp objects.

Avoid Harsh Chemicals

Do not use strong bleach, solvents or aggressive household cleaning products on textile, foam or rubber components.

Do Not Machine Wash

Machine washing may place unnecessary stress on the upper, bonding, Speedboard® and cushioning construction.

Air Dry Naturally

Allow the shoes to dry naturally in a ventilated area away from direct heaters, hair dryers and prolonged intense sunlight.
