While it's true that women need to cast out sexist stereotypes, this is more of a problem for men. A woman wearing men's clothes, short hair, and no make up is mostly accepted in polite society, thanks to all the work put in by gender-nonconforming women of long long ago. But a man in a dress and make-up, is not as easily tolerated.

You need to be asking men to shed their sexist stereotypes, and wear whatever footwear and clothes they please.

Edit: Personally, I never shave, never wear make-up. I used to exclusively wear pants and a t-shirt/tunic top for a long time, but I've recently switched to long skirts and tops/shirts/t-shirts, because I find skirts more comfortable. I own exactly one pair of slippers, and one pair of sneakers.
