Designed for Versatile Movement

The Cloud X 4 uses an X-shaped Speedboard® engineered specifically around flexibility and control during varied training movements.

Forefoot Flexibility

The X-shaped construction allows greater forefoot flexibility than a more rigid straight-line plate, helping the shoe respond naturally during lateral and multidirectional exercises.

Dynamic Training

The design is particularly relevant for workouts involving exercises such as burpees, box jumps, circuits and rapid changes of direction.

Power & Control

Speedboard® technology works with the cushioning platform to support controlled movement while retaining a responsive feel.

Soft Landings

Helion™ superfoam helps absorb impact during jumps, repeated training movements and everyday activity.

Responsive Take-Offs

The foam is designed to return energy as the foot transitions from landing into the next movement.

Training Stability

Cloud X 4 balances cushioning with stability so the platform remains suitable for multidirectional exercise.

Versatile Feel

Rather than maximizing softness alone, the cushioning setup is tuned for a mixture of impact protection, responsiveness and control.

Supportive Midfoot Cage

The midfoot cage wraps around the center of the foot to improve support and create a more secure connection to the platform.

Lateral Stability

Additional midfoot structure is particularly useful when training includes side-to-side movement rather than only forward motion.

Secure Heel

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

Training-Focused Lockdown

The combination of midfoot support, lacing and heel structure creates a more stable fit for active training.

Ventilated Construction

Breathable mesh allows airflow through the upper during gym sessions and active everyday wear.

Lightweight Feel

Textile construction keeps unnecessary bulk low and contributes to the approximately 226g official women's weight.

Plush Heel & Tongue

Softer materials around the heel and tongue improve comfort at common pressure and contact areas.

Technical Aesthetic

Visible knit and mesh texture reinforces the performance-inspired appearance of the Silver / Chambray colorway.

Silver-Grey Upper

Walking & Everyday Wear

Travel & Active Lifestyle

Grey Monochrome

Grey leggings, technical trousers or relaxed sweatpants create a clean tonal look around the Silver upper.

White & Cream

White, cream and off-white clothing emphasizes the clean, lightweight appearance of the shoe.

Chambray & Blue

Soft blue, navy or washed denim pieces connect naturally with the Chambray accent.

Black Contrast

Black leggings, shorts or cargos create stronger contrast and allow the pale upper to stand out.

Athleisure

Training tights, technical tees, lightweight jackets and performance tops naturally complement the shoe's intended use.

Minimal Everyday Styling

Straight-leg trousers, clean basics and subtle accessories allow the technical silhouette to work as an everyday casual sneaker.

Remove Loose Dirt First

Use a clean soft brush to remove dry dust and debris before applying water or cleaning solution.

Clean Mesh Gently

Use a soft cloth or soft-bristle brush with a mild footwear cleaning solution. Avoid aggressive scrubbing of the mesh.

Take Extra Care with Light Colors

Silver and pale-grey materials can show dirt more easily, so clean smaller areas gradually to maintain an even appearance.

Clean the Midsole Separately

Surface marks on the cushioning platform can be wiped gently with a damp microfiber cloth.

Avoid Harsh Chemicals

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

Do Not Machine Wash

Machine washing may place unnecessary stress on the mesh, bonding, cushioning and internal support components.

Air Dry Naturally

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