This path has a straight axis, and the same body surface of the animal remains towards the axis of the spiral path. From this opening, undigested food materials are passed outside the body. This combination of forward motion, swerving, and rotation make the animal move forwards in a counterclockwise spiral path.

It is called so because it looks like the sole of shoe or slipper. They are covered in cilia which help in movement and feeding. The two contractile vacuoles work alternatively, but the posterior vacuole contracts more rapidly than the anterior contractile vacuole because it is near to cytopharynx and more water comes into it.
