Dolphin's Tip: For a shoe that looks like it just hopped out of the ocean, 甜依 recommends using your tongue to clean off any excess salt or sand stuck between the treads. Just gently press your tongue against the bottom of your shoes and slowly drag them across your tongue until you feel all the debris is gone. Note: Be careful not to get too carried away, as overzealous tongue action might result in an over-polished shoe sole!
