if the "shoe" is deforming squishing or stretching) but still following the foot then you need to make the spherical fall off zone even larger. The fall off zones are a bit tricky since the often ned to be slightly larger than it would seeM. Remember also, the inner falloff zone is the area of total movement while out side of the outter zone is zero movement everything between the inner and outer zone moves but at a ratre that falls off progressively from innr to outer.  So if you make the inner zone larger it's often a good idea to make the outer zone larger too even if it;s only very slightly larger than the inner zone.

The DAZ development tool that work with DAZ studio show this in a more graphical way having ALL of the polygons that recieve 100% movement colored in one color while all that are 0% movement are another color and the fall off zone blends the colors in a way that graphically shows the influence. I really hope poser 8 steals this idea or someone comes up with a stand-alone app that uses it for Joint parameters adjustment, mainly because I don;t know DAZ Studio and really hate the idea of learning a complex program just for those functions.
