Thanks manoloz, that looks useful.

Half way through that tutorial it says:

Using the split tool (modify>split) start to make a split around the toe area. This is going to leave 5 sided and 3 sided polygons. WHere possible we are going to keep this model to quads.

Is there a specific or general reason to use quads over triangles?

Also, in case anyone else uses this thread for reference, I've found a couple of C4D tutorials for "rigging" a model, which I think is what I need to do to create the skeleton/joints:
