Read our review of the On Cloudmonster 2


Outfitter's Note: If you found your perfect fit with the original Cloudmonster, we recommend taking half a size down for the Cloudmonster 2.

The On Cloudmonster 2 is a road runner’s dream. This monstrous shoe gives your stride an unique forward-rolling that supercharges your run with energetic propulsion and an exhilarating bounce.

Perfect for everything from easy jaunts around the block to long tempo runs, the Cloudmonster 2 brings comfort and excitement to your training. A nylon-blend Speedboard® is sandwiched between On’s CloudTec® outsole and dual-density Helion™ superfoam midsole, giving you soft landings and powerful take-offs for an irresistible run.

See what our testers thought in our On Cloudmonster 2 review.


  • Upper: A soft, 100% recycled polyester mesh upper with a breathable, roomy fit keeps your feet comfortable for the long haul.
  • Midsole: The Cloudmonster 2 features On’s biggest CloudTec® ever and is combined with a monstrous dual-density Helion superfoam midsole for softer landings and better impact absorption. A nylon Speedboard is sandwiched in the middle for momentum and powerful take-offs.
  • Outsole: A closed-channel outsole keeps rocks and debris out while giving you the grip to run confidently.

What’s New

On is back at it again, this time with their biggest CloudTec cushioning ever. The new Cloudmonster 2 comes packed with almost 5 mm more cushioning underfoot. Designers also revamped the upper with 100% recycled polyester for a more breathable and accommodating fit.

Who It’s Best For

The On Cloudmonster 2 is best for runners and walkers looking for a neutral running shoe with maximum cushioning to soak up the miles in.

“I’d recommend the Cloudmonster 2 to runners who enjoy stability and responsiveness over an overly plush, pillow-like feel,” says Nate, one of our running shoe testers.

Why You’ll Love It

Featuring On’s biggest CloudTec® ever, you’ll love the Cloudmonster 2’s massive cushioning, mega bounce and maximum energy-return. It's a monster ride on the road with an unmatched forward-rolling motion.


The mesh on the upper is made from 100% recycled polyester. By using more sustainable materials and processes, On increased the overall recycled content to 24%.
