Side views of a feet are practically triangular shaped with a rectangle on top. The straight lines drawn indicates the ankles and toes where bending occurs.
A quarter view of a foot may look tricky but just follow these steps:
1. Begin with a trapezoid with rectangle on top.
2. Cut the pointy end of the trapezoid so it runs practically parallel with the top of the foot.
3. Bend the end of the foot where the toes should be. Add toes guideline if it helps you.
4. Finish drawing by curving out the lines a bit, adding ankle, and toes.
Not bad huh?
The drawing just below the side view illustrates two feet. Note that one is slimmer than the other indicating a female foot and a male foot. Feet drawing can differ just by a slight change in width or thickness and even length.
Finally, the front view, is also made up of rectangles and a trapezoid. All you basically need to do is draw in ankles and the toes.
Speaking of toes, lets take a look at how to draw them. On the right is a three step process to draw toes. Starting with just a guide, draw laying L’s for toes. Make sure the inner toe is the biggest with the last being the smallest. From there, draw in the toenails and you’re done!
Going back to the whole foot, we have here an example of the two sides of the foot. One side, if turned, has an arch. The other side, if turned, does not.
The side of the foot with an arch faces the inside while the archless side faces outwards. A trivial info but something you have to keep in mind when drawing the foot.
Lets look at another detail you have to remember: the ankle. On the right, we have a quarter and a front view of ankles. At quarter view, the ankle is reminiscent of a boomerang while the front views are slight bumps. Nothing to it!
Another aspect of feet is how they bend. Below is a drawing of a foot at rest and a vertical foot resting on the toes. At the ballerina-like stance, note how the top of the foot is pretty much straight and the back of the ankle is now scrunched up. The same scrunch would occur if the toe was bent inwards.
One last detail about the foot you must make note: the foot curves at the toes. Check out the example above with the slippers. The longest point is the big toe and grows less as it reaches the pinky toe. This is why shoes are generally shaped with a rounded end.
