Sorry Deisy, can't help too much with that.
Shoe boots are cute and useful toys for both to play. I have those, ankle and longer boots of my own as well, which always feel good with a short skirt (think of Mary Louise Parker - yum) For me for me it is shoes, so while sometimes playing booted, getting off using boots is not a regular thing. Anything footwear can appeal at times, Some time pre-teen, before I out grew them, I remember the excitement wearing and using sisters footwear, some long black patent boots in particular, and I am sure some fantasies would have involved the possibilities if she or her friends had caught me ....... .
I will keep in mind if I see something appropriate anywhere, but for now I found these
which may keep you busy
very busy .......
