On | Men's Cloud X 4 Training Shoe

The Ultimate Multi-Discipline Training Tool

Whether you are escaping the freezing Canadian winter for a high-intensity indoor HIIT class or hitting the local track for short, explosive sprint intervals, you need a shoe that can keep up. The Men's On Cloud X 4 is born from running but built for absolutely everything else. It takes the agile, lightweight DNA of the legendary Cloud series and tunes it specifically for the dynamic, multi-directional movements of modern cross-training. From burpees to box jumps, this is the disciplined, highly flexible tool you need in your gym bag.

Beneath the highly breathable, eco-conscious mesh upper lies a perfectly balanced engine. The midsole utilizes Helion™ superfoam and signature CloudTec® cushioning to absorb punishing vertical impact, keeping your joints protected during heavy, repetitive movements. Meanwhile, the integrated X-Shaped Speedboard® and secure midfoot cage provide the vital lateral lockdown needed for fast side-to-side agility drills and heavy lunges. Fast, responsive, and grounded, it delivers comfort and control across every workout.
