I created a pair of boots for Alyson using Blender3D. I can import the boots as a wave front object into Poser and even fit them to Alyson's feet. Obviously though, since they're basically just a prop at this point they won't conform to Alyson's feet. If you'll also notice the boots have heels on them.  So how do I use the set up room to make the boots conform to Alyson?

I have seen Tutorials on how to conform other clothes, but since these are boots and they had to be made to fit Alyson, or rather Alyson had to be made to fit the boots. How do I conform the boots?
