On Men's Cloud X 4 Sneakers - Versatile, Softer Cushioning

Our review of the On Men's Cloud X 4 Sneakers finds a versatile training shoe best suited for fitness lovers who want a softer, more flexible ride without sacrificing support. Born from running and refined for workouts, the Cloud X 4 delivers noticeably softer cushioning and improved forefoot flexibility thanks to a new Speedboard design, making it a strong pick for HIIT, gym sessions, and short runs where responsiveness and comfort matter most.

Key Features

• Softer cushioning: The midsole provides a more cushioned feel underfoot that reduces impact during short runs and high-rep workouts.
• New Speedboard design: Enhanced forefoot flexibility helps with quick transitions in dynamic training and sprint drills.
• Stable platform: The update improves overall stability so lateral movements and HIIT sequences feel more secure.
• Lightweight construction: The shoe remains light, which reduces fatigue during cardio sessions and longer gym circuits.
• Recycled materials: Upper and components include recycled polyester and TPU for a lower environmental footprint.

Who It's For

The Cloud X 4 is aimed at fitness enthusiasts who split time between gym workouts, HIIT, and short runs up to 5K; it performs well for no-load training days and cardio sessions where cushioning and flexibility matter. Runners who need a highly cushioned long-distance shoe or maximal road marathon cushioning should look elsewhere.

Also a good option for those who prioritize a modern, lightweight trainer with a secure fit and modest sustainability credentials thanks to high recycled-content materials, though buyers seeking heavy-duty hiking or trail protection should consider a different category.

Pros & Cons
