FAQs

Is the Cloudmonster 2 good for flat feet?

The Cloudmonster 2 provides a stable base; however, it is a neutral trainer. If you require significant arch support, you may consider using custom insoles.

Can I use these for track workouts?

Yes, they provide enough energy return for tempo work, though they are optimized for road surfaces.

Are these shoes waterproof?

No, the nylon upper is designed for breathability. They will get wet in heavy rain.

How long should these shoes last?

Depending on your running surface and gait, you can expect between 400 to 500 miles of consistent performance.

How do I choose the right size?

The Cloudmonster 2 fits true to size for most male runners. If you prefer extra room for foot swelling during long runs, consider a half-size up.

Troubleshooting

Debris getting stuck in the sole

The large CloudTec pods are designed for performance, but can collect small pebbles. Use a blunt tool or a stiff brush to gently dislodge debris after your run.

Sensation of slippage at the heel

Try the 'runner's loop' lacing technique to better lock down your heel without tightening the entire midfoot too much.

Setup, Compatibility & Care

To ensure the longevity of your Cloudmonster 2s, follow these guidelines:

  1. Break-in Period: While comfortable out of the box, wear them for shorter walks to let the nylon Speedboard flex to your natural gait.
  2. Surface Usage: These are strictly road runners. Avoid sharp rocks or deep mud, as these can lodge in the CloudTec pods.
  3. Cleaning: Hand wash with mild soap and cold water. Remove the insole and laces before cleaning. Do not machine wash or tumble dry.
  4. Storage: Always store in a cool, dry place away from direct sunlight, which can degrade the Helion foam over time.
