How to walk silently
Watch where you walk.
Moving soundlessly is much more difficult when you're walking on crunchy gravel and leaves than it is when you're moving over soft grass or dirt. To walk silently, assess the terrain and determine which path is the quietest.
Whether you're indoors or outdoors, you can consciously walk over materials that help you move silently instead of creating extra noise. If you're walking through the woods or in another outdoor area, try to walk on soft grass or dirt.
