ok, heres a simple way to do it, so long as you dont care about posing the feet

get Wings 3D, or another modeling program, and load V4 as an .obj (youll have to export her from DAZ as an .obj first, though)

highlight everything but the feet and delete. export the feet (individually) as .obj's

re-load them into DAZ and position them where you want them.

now, if you want to be able to pose the feet, just load 3 V4's, hide everything but the feet, and reposition as necessary. This method is a little...cumbersome, though
