That's cool, sniffles!
Two years ago, my students put up a 10-minute skit (in Mandarin) based on one of the chapters in the XAJH novel. Off-the-shelf costumes were (and still are) non-existent where I live, so I had a mighty fine time haggling with the neighbourhood seamstress as to what was right/wrong and what could/couldn't be done during the process of making the outfits. (The seamstress knew zilch about wuxia).
If you have problems getting/using suitable boots, try wearing a pair of plain-coloured canvas ballerina flats with white opaque knee-high stockings/socks. Add a small puffy ball of threads (like a miniature pom-pom) to the front of each shoe. Looks good with long trousers/gowns, and the top of the stockings/socks won't show unless you lift your clothes, and that's something you won't do anyway.
You could tweak things a bit and look like a middle-aged West-Asian wuxia heroine, such as someone who might live out in the areas occupied by current-day Xinjiang like the female martial arts teacher (her name escapes me at this point; someone, please help) of Huo Qingtong from the
Book and the Sword.

I think it would be fun to dress up in wuxia-type clothes, but the weather around here is too hot to wear layers of clothing (for authenticity) for long periods of time.

Edit:
Another idea for the shoes.
If you still want to wear boots, wear your ballerina flats and have your friend sew you some canvas "socks" that go on, on the
outside of those shoes. Add some anti-slip material as soles, and there, you have some makeshift boots to take photos in, and walk around indoors for a bit.
