Maximal CloudTec® Provides High Cushion with High Energy Return

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.

Great Product - Incredible Price!

I could not be happier with the overall experience for this purchase. Everything from submitting order, the timely communications and on time delivery of a great On shoe that I love. Did I mention the incredible price?!? I understand that it is a Cloudmonster 2 model, but I can tell you that no one else has the price that you provided. Look forward to more purchases down the road!

Love these Shoes

The third pair of these that I've bought, after originally having them recommended in-store as a good balance of comfortable and cushioned but with a more solid feel. They seem to last a few hundred miles before wearing out - is that good? Bad? Don't know, but they're the most comfortable shoe I've ever owned and I love wearing them.

Cloudmonster 2 - Feels like cloud

The Cloudmonster 2 really lives up to its name—it feels like running on a cloud. As someone with wide feet, this version stands out. I tried the Cloudmonster 1 and 3, and both felt too narrow, but the 2 fits much more comfortably without squeezing. It has a smooth, gliding ride that makes longer runs feel easier. If you’ve struggled with narrow fits in other versions, this one is definitely worth it.
