FAQs

Can I use these for running?

These trainers are designed for casual daily wear and walking. They lack the structural support needed for running or high-impact athletic activities.

Are the laces adjustable?

No, the laces are elastic and designed for a slip-on fit. They cannot be tightened or replaced with standard laces.

Are these shoes machine washable?

We recommend hand cleaning with a damp cloth. Machine washing can compromise the memory foam integrity and the glue used in the construction.

Does the wide fit make the shoe run large?

The wide fit provides more volume in the toe box and midfoot. If you have very narrow feet, you may find them to have more room than a standard-width trainer.

Can I replace the insole with my own orthotics?

The memory foam sockliner is generally meant to be part of the comfort system; check if yours is removable, though replacing it may alter the intended fit and feel.

Troubleshooting

The fit feels too loose in the heel area.

Ensure your sock choice provides enough bulk to fill the space, or consider an aftermarket heel grip if the size is slightly too large.

The elastic collar feels restrictive after long wear.

Take a short break from wearing the trainers to allow your circulation to normalize and the elastic material to relax.

Footbed is slippery after extended use.

Remove the sockliner if possible, let it air dry completely, and wipe the interior of the shoe to remove any trapped moisture.

Setup, Compatibility & Care

These trainers require no setup; simply slip them on and the elastic collar conforms to your foot. To maintain the life of the Cloudfoam technology, avoid soaking the shoes in water. If they become dusty or lightly soiled, wipe them down with a damp cloth and mild soap. Air dry them away from direct heat sources, such as radiators, to prevent the foam components from deforming or drying out prematurely. Store them in a cool, dry place when not in use to preserve the elasticity of the collar and laces.
