FAQs

Are these shoes suitable for flat feet?

The Cloudmonster offers neutral support; however, its high level of cushioning provides comfort for many runners, regardless of arch type.

Can I use these for gym workouts?

They are primarily designed for road running. For heavy weightlifting, a flatter shoe is recommended to provide a stable base.

How often should I replace my Cloudmonsters?

Most running shoes provide peak performance for 300 to 500 miles, depending on your running style and surface conditions.

Do these run true to size?

The Cloudmonster generally follows standard sizing, though many runners prefer to go a half-size up to allow for foot swelling during long runs.

Are these shoes waterproof?

No, the breathable mesh upper is designed for ventilation and will not keep water out.

Can I machine wash these trainers?

It is recommended to hand wash them to preserve the integrity of the foam and glue; machine washing can cause premature wear.

Troubleshooting

Debris stuck in the cloud elements

Use a blunt tool or pressurized water to gently dislodge stones or twigs from the gaps in the sole.

Feeling of instability during cornering

Ensure the laces are tied securely using a runner's loop to lock the heel in place and prevent lateral foot movement.

Pros and Cons

Pros

  • Exceptional impact protection for long-distance runs
  • High energy return via the Speedboard insert
  • Breathable material keeps feet cool during intense activity
  • Reliable grip from the rubber outsole
  • Smooth gait transition thanks to the rocker geometry

Cons

  • Maximalist cushioning can feel heavy to some users
  • Large sole profile lacks ground feel
  • Not intended for technical trail or cross-country terrain

Setup, Compatibility & Care

To ensure optimal performance, verify your sizing for a comfortable fit with adequate room in the toe box. The shoes should be laced snugly but not tight enough to impede circulation. For care, keep your Cloudmonsters clean by wiping them with a damp cloth after muddy or dusty runs. If they become heavily soiled, hand wash them in cool water with mild soap and air dry them away from direct heat sources, such as radiators, to prevent damage to the foam cushioning components.
