I started reading a book called "Learning Maya 7: Foundation," and I'm up to the IK chapter.

In the this chapter, they want me to add an RPSolver Handle on the legs of the model, which worked out fine.

Though, when they wanted me to create the foot so that it would "roll from the heel to the toe," the front of the foot would actually connect it's self to the heel of the model.

Here's a video of what I did:

Can anyone tell me what I'm doing wrong?
