I don't know if it really affects the model but you made a typo with the "rToes" . 
I've never made clothes for Apollomaximus, and I never used Phi builder, does this program makes bodypartgroups for the object? You can check that with the group editor in poser.

Edited: I see some others have given some valuable tips, I had some tips for fitting shoes for Victoria 4 in a thread some weeks ago. Steven is right about  the internal names, I had forgotten about that, the object groups have to be same to make it work.
