Drawing feet on the fashion figure: high heels vs. flats
Let's be honest, drawing feet is annoying. I find drawing flat shoes to be more challenging than drawing heels. Flat shoes often end up looking like little boats or skis or Donald Duck's flippers—not cute.
Out of frustration, I had a photoshoot with my feet to try and figure out how to draw heels and flats with ease.
In the far left image, my heels are planted firmly on the ground (my feet are completely flat). In every following image, I am raising my heels slightly higher; the far right image displays my maximum heel hight. From studying this progression of heel hight (while standing forward in an upright position), I noticed this relationship:
The lower the heel, the more the feet face out away from the center body line.
The higher the heel, the more the feet face in towards the center body line.
To help illustrate this point, note the red arrows on the below sketch.
Also note that the placement of the feet from the bottom of the page stays consistent (this is the floor and floors don't move). The knees and ankles gradually gain height from the bottom of the page as the figure gets getting taller with the new heel height.
I recommend exploring this relationship by standing in the mirror and slowly raising your heels off the ground.
