You could explain your situation but that is tantamount to asking her to change her life style just for you and putting the guilt trip on her. She is probably just carrying on as normal living her happy life in clogs.
If she has to pass your appartment to get to hers put a sign on your door that says something like "Quiet please shift working sleeping
Thank you for your consideration.
If that doesn't work a non threatning, non agressive visit is in order to explain your situation. Not sure about the slippers I dea. Because she wears clogs that sounds a bit "Birkenstock" so maybe a pair of Moccasins.
