Modeling the Feet...

Step 128.
In the top view create a spline that resembles half of an ankle outline. Something close to a pear will do.

 

Step 129.
Select the entire spline and copy/flip/attach. This will give you the ankle cross section.

Step 130.
In the left view begin extruding the spline ring to form a foot shape. Scale and rotate as you extrude.

 

Step 131.
Continue extruding until you get to the toes.

Not very pretty is it? But its pretty close, just needs some tweaking.

 

Step 132.
Tweak the points on the foot to resemble the shape you want. Feet come in all kinds of shapes, and the wrong shape foot on a body can absolutely kill the since of realism for the entire model.

Take your time, take off your shoes and look at your own feet. Better yet take pictures of feet and use them as rotoscopes, it'll make your life so much easier.

 

Step 133.
Create a spline that resembles half of big toe. Lathe it.

The toe to the right isn't to bad for a top view, but its way to fat for a side view.

Step 134.
Rotate the toe to the side and begin tweaking it to look like a big toe.

 

Step 135.
Place the toe approximately where you expect it to go on the foot.

 

Step 136.
Duplicate and tweak the big toe to create the remaining toes. They don't have to be perfect.... You'll probably tweak them allot more once you have them connected to the foot.

Make sure they all sit flush on the ground though.

Curl the toes downward as you move out toward the pinkie toe. This will add some realism.

Humans have crammed our feet into poorly fitted shoes for so long that our toes tend to get squeezed inward as we get older, so tilt your smaller toes toward the big toe. A little for a toddler and a lot for an older person.

 

Step 137.
Join the toes to the foot and each other by attaching all the inner and outer splines to each other.

 

Step 138.
Now play connect the dots again attaching splines from toe to foot.

Notice that I created one more spline to go between the toes. And of course lots more 5 point patches in-between the joints.

 

Step 139.
Tweak the foot to shape it into its final form.

Select the whole foot and group it. Call it left or right foot. Give it a skin tone for its color.

 

Step 140.
You can attach the foot to the leg or just insert it into the pants leg. Either one is fine.

Congratulations! You're done modeling. Now you can texture, rig and animate him.
