Feet - More Complex than you might think

As someone who has always had trouble drawing the foot region in my sketches this particular exercise was enlightening and a bit frustrating.

The complexity of the foot starts from the bone structure:

The calcaneum is the heel bone, which bears a great amount of the bodies weight.  The talus is the "ankle" bone, providing a base for foot rotation.  the Cuboid, Cuneiform, and Navicular (from the word for boat, derivative of the bone's shape) bones begin to form the arch of the foot and add further weight-bearing strength to the foot.  The Metatarsals form the base of the digits, they help distribute weight evenly across the foot for balance.  The Phalanges, just like in the hand, are the digits that have somewhat independent mobility and allow the foot to grip things (however usually not particularly well).

These bones are relatively small, and shaped with precision for a precise purpose, and without the proper scale and the proper orientation and the proper curvature, the entire foot is suddenly misshapen and unnatural looking.

My drawing contains two feet: one in the medial position (from the inner arch of the foot) and the anterior (the front) getting a good look at the toes.  While the medial view was challenging, I'm pleased enough with how it came out.  The anterior view proved problematic due to what I perceive to be issues with foreshortening.

With an anterior view of the foot you are dealing with a shape that as it narrows, grows taller and overall thicker and this particular view was very very challenging and I am not pleased with the results.  

I have drawn simplified versions of the foot in other drawings since, and the more thorough understanding of the underlying structure has improved these executions, however I think I will continue to struggle with this complex form in detailed studies.  And the only remedy is, of course, more practice.
