I have this new foot now, with fewer vertex. I think though, that I can't do a proper weight paint here, bc there are no vertex inside the mesh, but only outside? Actually, I tried this one, and then I subdivided the mesh to have these lots of vertex. was that wrong and how can I weight paint properly on this one?

Actually, the automatic weights do well, but for each bone, it is affecting also the other parts. when I try to paint it, it makes weird changes due to the lack of vertex. But I know that I can't weight paint it properly without having these jagged edges again. :(
