In general, most of the rendering techniques are pretty much a "do and repeat" process of each different part of form, highlight and shadow.
Once you start to develop your skills it gets pretty easy and just requires some patience and time. Nearing the end of the rendering, you can add additional effect by erasing parts of your body shadow in highlight areas, adding white airbrush ontop set to Lighten for more highlight, and add small pinprick highlight dots (I remember them being called "birdshit" in traditional marker rendering classes when exectuted with guache or white-out) for more pop.
In the end, the final look and effect is up to you. Some tend to go with a more over the top style including lens flares and overlayed sketchy lines, but I generally prefer to keep things as real as possible. Small details I like include reflections of a ring flash in the shiny plastic heel counter made from Illustrator artwork, and used also on the body of the shoe in different scales and opacities.
For my final rendering, I did the same again for the medial side, and then combined two TIFFS of the renderings together with a background of black to white gradient and low opacity sketch for the final view.
Thats all! In total, this rendering of lateral and medial side took me about 12 hours and I ended up with 2x40 Mb PSD files. As a matter of course, I dont normally do renderings like this for work in the process of design and development as it is so time consuming, but sometimes a good visualization can help indeed help present a concept that is hard to understand through sketches. Still, I'll take a pen and paper any day.
