These Pikolinos men's penny loafers are super easy to use. Just slip them on your feet, and you're ready to go. For daily use, they're great for work, casual outings, or even a semi - formal event thanks to their olmo brown color. When it comes to maintenance, use a soft leather cleaner to keep the 100% calfskin leather upper looking good. Avoid getting them too wet as it might damage the leather. You can take out the removable insole and let it dry separately if it gets damp. As for the synthetic sole, a simple wipe with a damp cloth will do the trick. Be careful not to wear them on very rough or abrasive surfaces to avoid excessive wear. And if you want to keep the snug fit, don't over - stretch the shoes when putting them on or taking them off.
