Footprints in sand

Footprints in snow

Footprints are shapes on the ground where people or animals walked. The foot touches the ground and at that position a footprint appears afterwards. This can happen because the ground is muddy or snowy and the foot sinks a little bit into the ground. Another possibility is that the foot is dirty or has fresh color on it. When the foot touches the ground the dirt or color remains at the ground and marks the position of contact.
