A woman travels often, and when she does, she stays in hotels. Every night, before going to bed in a hotel, she takes off her shoes and puts one of the shoes into the hotel safe.

Why?
Possible Reasoning
This ensures she will remember to check the hotel safe before leaving the room in case she has stored any valuables in there. It's common for people to forget to check the safe before they leave but the necessary retrieval of the shoe forces this.
Because she is a frequent traveler, often staying in unfamiliar hotels, she keeps a reserve of money in the heel of one of her shoes and, being a sound sleeper (or maybe needing to take sleeping pills to ensure a sound sleep in unfamiliar surroundings), takes the precaution of putting this shoe in the hotel safe.
Alternate:
She often gets lonely, but is also lazy, so every night she calls the Front Desk to ask someone to please come up and unlock her safe; she can't possibly walk down to the Front Desk herself, as her shoe is locked in the safe.
