Since modeling the fingers of the leg will be time consuming and repetitive in 3D Studio MAX ( 3ds max ), I'm leaving it to you as an exercise. Don't worry. The process is just similar to the way you modeled the model / character's thumb, in our arm modeling tutorial.

Close the foot's tip, by connecting the vertices using the 'Create Line' tool, as shown in the figure.

Now it's time for refining the shape of the model / character's leg. Take a good look at the figures given and adjust the vertices in your model / character. Make sure that you give a pronounced calf and you make the thigh considerably large and curved. Taking some time to experiment in 3D Studio MAX ( 3ds max ) will make your model / character look pleasing.
