Like to mix up your workouts? The Cloud X 3 AD will take you from the gym to a 5K in a flash. The full-length Speedboard® propels you forward, faster, while the raised sidewalls and wide base keep your feet secure and stable. Grip pads on the outsole offer enhanced traction during lateral movements. The mesh upper is made with 100% recycled polyester for maximum breathability. Inside, the 50% bamboo lining helps to keep your feet cool and dry while you work up a sweat. The finishing touch? A reinforced toe cap for added durability and protection during training.
