Shoe Specifications

Ultralight and ultra-flexible for feel-good workouts

Born from running. Made for everything. The Cloud X 4 is the versatile training shoe for fitness lovers. Now with a new Speedboard® design for better forefoot flexibility, plus a softer and more cushioned feel underfoot.

Product Highlights

More stable. More soft. - For lateral stability, the midfoot cage and star lacing system wrap around the foot. Softer, plusher materials in the heel and tongue provide enhanced comfort.
Softer cushioning - The Helion™ superfoam midsole feels softer and more cushioned underfoot. Extra padding in the heel means more comfort while running.
Feel good shoes - The breathable mesh upper is made with recycled polyester. The majority of colorways feature a dope-dyed upper – a process that requires 90% less water compared with standard dyeing techniques.
New Speedboard® design - Take on movements like mountain climbers and burpees in total comfort with the new X-shaped Speedboard®. Made with a pliable nylon-blend for better forefoot flexibility.
