Quote - Well, the shoes in the picture don't even have IK chains, so that's not the problem.  The issue seems to be the scaling of the thighs and shins.  I apply the same scaling to Cookie and the shoes, but the shoes still fail to conform properly when bending Cookie's shins.  Any ideas how I could fix it?

Ah your figure modifications include scaling, unfortunately that is a known issue in poser, conforming clothing does not work properly with scaled bodyparts. has to do with how scaled joint centers do not translate between base figure and conformers.
