Your goddess has just returned from a party where she was dancing all night long and her feet are sweaty and she needs you to take care of them. You could clean her shoes as well, but that's up to you. She's to tired to make you to do the shoes and her feet are a must. She puts them in your face as you're laying on the ground at her feet and presses them to make you smell them. Now worship them, massage them and make her happy in any way she wants. After all that's why you're there, to serve her and be at her feet and doo anything for her feet. So do it.
