Never machine wash your shoes!  Machine washing may affect the water repellence of the outer cover.
Only wash your shoes by hand using a damp sponge.
Wash your shoes in clean water if there are mud stains, as they can damage the leather parts.
We suggest you change the insole more often than you change your shoes. You will thus extend the use comfort, increase reliability over time and optimise waterproofing and breathability of your Novadry shoes. Moreover, it enables you to keep this antibacterial treatment even longer. (depending on the model)
