On Cloud X 4 Training Shoe | Women's Cross-Training & HIIT

The Ultimate Multi-Discipline Training Tool, Sustainably Redefined

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 Women'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 for feel-good, powerful workouts.

Beneath the highly breathable mesh upper lies a perfectly balanced, eco-conscious engine. The midsole utilizes Helion™ superfoam to absorb punishing vertical impact, paired with a revolutionary 50% bio-attributed Zero-Gravity foam made from renewable materials like waste cooking oil—cutting carbon emissions by 20%. 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 sustainably built, it delivers comfort and control across every workout.
