To use these Pikolinos Ávila men's dress shoes, simply untie the laces, slip your feet in, and tie them up for a snug fit. They're great for both formal and semi - formal occasions. When it comes to care, avoid wearing them in extremely wet or muddy conditions. If they get dirty, use a soft, damp cloth to gently wipe the leather upper. Let them air - dry naturally away from direct heat. For the synthetic sole, you can clean it with a mild soap solution. Periodically, apply a leather conditioner to keep the calfskin leather looking its best and to maintain its softness and durability. Also, when not in use, store them in a cool, dry place. You can use a shoe tree to help them keep their shape.
