Soft, yet responsive, the On Cloudmonster 2 is the perfect everyday trainer for runners who want to feel energized without sacrificing cushioning. A dual-density Helion Superfoam provides a soft step-in feel and soft landing on the run, while retaining plenty of responsiveness for a smooth toe-off. A new nylon-blend Speedboard is sandwiched in the midsole with a slingshot shape for smooth transitions. An engineered mesh upper caps this off with a breathable and minimalist look and feel.


We’re accustomed to thinking of the workhorse daily trainer as a purely utilitarian tool. Traditionally, aesthetics go out the window as long as it reliably performs day after day and mile after mile. The On Cloudmonster 2 reimagines that paradigm. This is a daily trainer that looks as good as it feels, which is why On continues to capture the hearts and minds of runners of all stripes. With all the cushion the Cloudmonster 2 packs in, you’re getting a bit of a heavier shoe, which means you’re probably not going to find yourself doing much speed work in it. But, for a shoe you can lace up each day and count on to perform, you won’t do much better than the On Cloudmonster 2.


The On Cloudmonster 2 features dual-density Helion Superfoam which provides a soft step-in feel with a firmer and snappier ride, especially in the forefoot. This serves to separate the shoe from its max-cushioned cousin, the On Cloudeclipse, which goes all in on the softness. The upper is a retooled engineered mesh that is lighter, thinner, and even more minimal feeling than that on the original Cloudmonster. The result is a shoe that is super accommodating to runners with wider feet.


  • Runners of all abilities looking for a high-cushioned everyday running shoe
  • Walkers of all abilities
  • People who spend all day on their feet for work
  • Fashion-conscious runners looking for a shoe that looks good while offering plenty of cushion


  • Helion – dual-density Helion Superfoam maximizes cushion and energy return
  • Nylon Speedboard – new Speedboard sandwiched in the midsole for smooth transitions
  • Grip rubber – enhanced traction pattern for traction and durability
  • Engineered mesh – redesigned upper increases comfort, lockdown, and breathability

  • SIZE: Slightly large (runners between sizes should consider sizing down)
    • HEEL: Moderate (thin tongue and minimal padding combine for a slightly wider fit)
    • MIDFOOT: Moderate (wide fit, but gusseted tongue provides a secure fit)
    • FOREFOOT: Wide (even runners with wider feet should have plenty of wiggle room)


    • CUSHION: The On Cloudmonster 2 has a high level of firm, responsive cushioning. For a softer ride, we recommend the On Cloudeclipse.
    • PRONATION: The On Cloudmonster 2 doesn’t have any support built in for overpronators. For a more stable shoe, we recommend the On Cloudstratus 3.
    • SPEED: The On Cloudmonster 2 is too heavy to really go fast. For tempo days or races, we recommend the On Cloudflow 4 or On Cloudboom Echo 3.
    • OTHER BRANDS: Shoes from other brands similar to the On Cloudmonster 2 are the Hoka Bondi 8, Brooks Ghost Max, and Altra Via Olympus 2.
