How to use: Simply put on these shoes like you would any other pair. They're great for work or other activities where you need comfort and safety. Note that these shoes are not compatible with aftermarket insoles or orthotics, so don't try to insert them. Maintenance: To keep your shoes in good condition, clean them regularly with a soft brush and mild soap. Let them dry naturally away from direct heat. If they get wet, the waterproof membrane will help keep your feet dry, but still make sure to dry them properly to avoid any damage.
