Unleash your inner beast with the On Cloudmonster 2, the second-generation trainer that redefined what a high-cushioned running shoe could be. The Cloudmonster 2 sports a revamped upper and lining, made from 92% recycled polyester, and uses less TPU overlays. The result is a sustainably made, lightweight, and breathable upper.Underfoot is dual-density Helion™ foam that provides a softer cushion with a higher amount of energy return. Combined with Helion™ are the maximalist CloudTec® pods, absorbing more impact on the road while returning more to your run. The amount of cushion underfoot has been increased by 6 mm from the original to the Cloudmonster 2.Sandwiched within this midsole foam is a slingshot-shaped, nylon blend Speedboard®. This addition provides a high propulsion experience when transitioning from forefoot to midfoot. Less energy in, more energy out.
