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. Details: 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.
