What you have there, I'm guessing, is shoes that don't have bendable toes - because the real shoes wouldn't have them either. Most vendors of that sort of shoe will provide a foot pose which will put the figure's feet in the right orientation. If not, bend the toes upwards until they sit inside the shoe (or just make them invisible). Then bend the feet down until the shoe sole is parallel to the floor. It's easiest to do this if you look through the left or right camera. You'll probably want to turn off IK for the feet as well.
