This Tutorial takes you through the step-by-step rendering process of a basketball shoe using Sketchbook Pro along with some textures created in Adobe Illustrator.

First, begin your design with a simple line drawing. Decide on a perspective view for this demo I chose a typical Lateral side-view. I typically do several quick studies of various design lines, once I like a particular direction, I commit to it and expand those lines with more detail. From here we can move to the rendering phase.
