To use these Pikolinos Marbella loafers, simply slip your feet in. They're great for casual summer outings like beach walks, picnics, or just strolling around town. When it comes to maintenance, keep them away from sharp objects to avoid scratches on the calfskin leather upper. You can clean the leather with a soft, damp cloth and use a leather conditioner to keep it looking new. After getting wet, let them dry naturally away from direct heat. And remember, you can take out the removable insole to air it out and keep the shoes fresh.
