No advice on the shoe problem but I'd love to know how you're rendering skin that is intersecting the shoe without getting that blue tint along the edge where it intersects.  If I so much as have an arm intersect along the side of an abdomen, I get a horrible tinted line where it intersects.

Happens whenever I use SSS.

 

That usually happens when you have the two items that are close and are in the same scatter group,  in your example the arms would need to be in a different scatter group than the torso.  Not sure where this would have a relavence to the shoes though.

 

 

I use Poser 13 on Windows 11 - For Scene set up I use a Geekcom A5 -  Ryzen 9 5900HX, with 64 gig ram and 3 TB  storage, mini PC with final rendering done on normal sized desktop using an AMD Ryzen Threadipper 1950X CPU, Corsair Hydro H100i CPU cooler, 3XS EVGA GTX 1080i SC with 11g Ram, 4 X 16gig Corsair DDR4 Ram and a Corsair RM 100 PSU .   The desktop is in a remote location with rendering done via Queue Manager which gives me a clearer desktop and quieter computer room.
