Where can I find/buy 3D shoe lasts?


I am interested in shoe modelling, and I would like to find some shoe lasts to practice on.

I am completely lost on where to find these. I have searched far and wide on 3D modelling sites, but didn’t find the type I was looking for (high heel). I know there are programs specifically for modelling shoes, but they are not very accessible/affordable for an individual.

Where can you find shoe lasts? I am happy to pay for one. Please let me know, or if you wouldn’t mind sharing one, I would be extremely grateful.
