To keep your feet happy in your Howson shoes for as long as possible, nothing could be simpler: the ideal place to keep them is somewhere cool and dry, away from any source of heat (central heating, veranda, direct sun/UV), and well away from humidity and dust! And to give them a facelift: soapy water, a wipe with a damp sponge on the upper of the shoe, and that's it! An extra tip: drying them thoroughly will reactivate the water-repellent treatment (don't hesitate to use a hairdryer). If the effect disappears, use a reactivating spray to bring it back to its former glory! Oh yes, and by the way... For these shoes, forget the washing machine and keep the iron under lock and key!
