The Orpyx SI sensory insoles with the magnetic USB charger are water resistant. For example, if it is raining, the insoles can still be worn. The insoles have a USB port at the back of the heel that should avoid being submerged in water.
If the Orpyx SI sensory insoles get slightly wet, remove them from the shoes and allow to dry thoroughly before use. Do not submerge as this may cause the insoles to stop functioning properly. To clean, gently wipe with a damp cloth or disinfectant wipe.
