Worsted weight socks would go even faster. But even in fingering weight it is only 40 stitches cast on. Leg lenght is 2 1/2 inches to 3 inches long. Foot is the same as the leg. So they don't take all that long to do. There are links to patterns at the A4A blog.
Great way to practice making socks, if you always wanted to give them a try.
