how do I model a foot??
Search for a tutorial here or on google. I’m sure theres a tutorial out there somewhere that describes this. If not in blender then in some other 3d program which can easily be translated into blender.

It looks like it belongs here, I thought this section was for questions about modeling?
EDIT: Oh I see now, it was moved from the finished projects forum, my bad 
Just download someone else’s foot, check out the topology, make your own. The end. And yes, you posted in the wrong forum. In fact, every single one of your posts has been in the wrong forum (yes, including the one requesting nude women meshes)
