IK chains were turned off for this figure. The feet and toes of the figure move independently of the shoe. I do notice that selecting the foot-part of the shoe highlights the entire shoe part of the boot, including the toes. I might need to re-Obj2Cr2 this one.

BTW, when I work on models in Blender3D, they are matched to a zeroed V4 model (meaning, her toes are pointing downward. And then, that is how the boot is imported. Any suggestions about this approach?

Also, the toe part of the shoe appears a bit different to what it looked like in Blender3D.

I guess this is more a topic for your forum, though, maybe?
