Some time ago I had started modelling some simple sandals for G8F. But after G9 came out, I adapted everything to the new character and made the shoes as a unisex model. They fit pretty much most of the shapes that are available for G9 so far (I haven't tried Josie yet).
For the shape and colour schemes, I was inspired by Amazon's Essentials series, which also gave me the name: Myrina - Queen of the Amazons. I hope Jeff B. doesn't mind ...
