These Crocs require minimal setup. Simply unbox them and they are ready to wear. For initial use, you may want to adjust the pivoting heel strap to find your preferred fit—either forward for a casual slide or backward for a more secure feel.Compatibility is broad, fitting comfortably with casual attire. Please note the wide fit characteristic of Crocs; if you have narrow feet, consider sizing down from your usual UK size for a more snug fit, as US sizing is embossed on the sole.Caring for your Pokémon Classic Clogs is exceptionally easy. To clean them, simply rinse with water and mild soap, then allow them to air dry. Avoid harsh chemicals or extreme heat, which can damage the Croslite™ material. The Jibbitz™ charms can be removed and re-inserted as needed for cleaning or customization.
