The updated women's On Cloud X offers an energetic and powerful ride that’s fit for any workout. On primed the Cloud X for explosive movement in every direction by packing it with Helion foam. On’s premier foam works with a springy Speedboard tucked inside the midsole to energize every step. Designers added raised sidewalls around the shoe to bolster the stability and make it feel more agile, whether your workout moves you straight ahead or pulls you in every direction you can imagine. On created the upper from a flexible but tough engineered mesh. The function-focused weave of the mesh boosts durability but also allows the shoe to breathe when your workout heats up. With a no-sew design to maintain a comfortable fit, the women's On Cloud X is right at home on the run, in the gym or wandering around town.
