Using these Pikolinos shoes is simple. Just slip your feet in and adjust the elastic laces for a snug fit. They are suitable for various casual occasions.

For the insole, you can remove it and air - dry it if it gets wet. Also, don't over - tighten the laces to prevent damage to the elastic. With proper care, these shoes will serve you well for a long time.
