I have a recurring problem with some shoes conforming properly to v4.2 with Morphs++.  I like to set Leg Length to 1.0 to get longer legs on her.  But some of the conforming shoes end up not staying properly on the feet, instead they end up being "attached" higher up on the shin.  None of the available parameters on the shoes seem to work in getting the shoes where they need to be.  Other shoes I purchased don't have this problem.  How can I get the shoes to stay conformed through this simple morph?
