Jules53757: Yes, that bit doesn't seem quite right. I only saw a crease before I rendered, but now it looks more like a step. Maybe I missed a vertex when setting up the falloff zones. But I think to get the big toe to bend up realistically with the tendon poking out and such, I'll definitely need a JCM.

Fisty: I assume you have the joint editor tool (comes with either the figure setup tools or the figure setup tool bundle)? Select that and select the body part you want to mirror. Then open the tool tab and click on the little triangle/arrow thingie in the top right corner of its pane. You'll find an entry "Mirror Joints..." in the drowdown menu.
