Error?

Uh oh! You can see his foot poking through certain areas of his leg, which isn't good at all. But I figured out how to fix it. It did, unfortunately, involve going back into the model and playing with the vertexes, making the end of the foot scaled down so it doesn't reach the outside of the leg. I was worried about playing around with the vertexes of the model as I know this sometimes resets the rigging of the hands and face etc.

I appear to have avoided it this time. I'm guessing this is because the feet are NO WHERE near the head and hands, so they have stayed relatively unchanged. Either this, or because I haven't made any actualy changes to the amount of vertexes or polygons on the model. So it's ok.

I would hate to re-rig the hands again. I've had to do this process about 10 times now...
