Good points there WILL.
I think bare feet would indeed be the best solution. Though for the game it would probably not matter if it are shoes or bare feet. They probably wont be visible anyway.

But anyway, despite all problems with the rig, I have completed a test animation of the zombie walking. You can view it here.
Personally I think I've captured a convinsing walk cycle, although I realize the arms still are a bit too stiff at the moment.

Next time I'll have feet included
