If you're kicking down the door, the normal situation when you find a Curse is that the Curse gets applied and discarded (unless it's persistent, like Curse! Chicken On Your Head, in which case the card remains on the table as a reminder). Regardless, when a Curse is canceled, it gets discarded (i.e., using a Wishing Ring doesn't mean the Curse goes into your hand). In this particular case, the Sandals of Protection mean that the Curse has its effects canceled, so nothing happens to the person kicking down the door, and the Curse would get discarded as any canceled curse.
