On Running Cloud X 5 Running Shoe – Men's

Built for athletes who split time between the gym and the road, the Cloud X 5 is our top pick for cross-training and short runs. Helion foam and deep flex grooves replace the old Speedboard, giving you natural foot mechanics and real rebound without stiffness. CloudTec cushioning handles lateral cuts and heavy lifts just as well as easy miles.

• CloudTec® cushioning tuned for multidirectional movement — absorbs impact on lifts and lunges without killing your ground feel during lateral cuts
• Helion™ superfoam midsole flexes and rebounds across gym floors, pavement, and mixed surfaces without packing out under repeated use
• Deep flex grooves replace the Speedboard for more natural foot mechanics and better range of motion through dynamic, high-rep movements
• Breathable mesh upper with padded tongue and secure heel wrap locks your foot in place whether you're deadlifting or running easy miles
• 8mm drop, 30mm heel stack, 10.2 oz — enough cushion for all-day wear in three colorways: Black/Black, Frost/Alloy, and White/Black
