Here's some photos of the setup, the shoe, and my progress on the drawing. It's still far from complete.
The difficulty with drawing from life rather than photos is that each eye sees a slightly different image. For instance, the dark inside part behind the main strap isn't visible in the photo since it was taken from my right eye perspective. When I had the camera lined up to my left eye perspective, the toe straps took on a completely different arrangement than what I'd drawn. It's a challenge to combine these two images.
