To wear these Pikolinos penny loafers, simply slip your feet in. They're great for various occasions, from casual outings to semi - formal events. When it comes to maintenance, use a soft, damp cloth to clean the calfskin leather upper regularly. For stubborn stains, you can use a mild leather cleaner. Let the shoes dry naturally away from direct heat. The removable insole can be taken out and washed gently with mild soap and water, then air - dried. Avoid wearing these shoes in very wet or muddy conditions to preserve the leather and the synthetic sole. Also, store them in a cool, dry place, preferably in a shoe box, to keep their shape.
