Take a strip of sand or another type of soft earth and walk over it. Look back and trace your steps minding the gap between strides, the depth of the heel and toe and the drag if any of the earth in the direction of the walk. Next cover your path with leaves or soft branches and walk again over it. Squat and follow with a knife or a thin branch to follow your tracks as you are projecting from what you have seen before and following to disturb the cover as least as possible. Follow this by removing all signs of your track in any way you can so that another person will not know you were there. Think that when you follow someone you can be followed as well and the more you stay in one place the deeper and harder to undo the track is.
