To accomplish this one would have to walk rigid & like a puppet.Posted by RedeZra (here)
an imprint depends on the viscosity of a material and so stepping on moist sand or mud would not be the same as stepping on solidifying granitePosted by Bryn ap Gwilym (here)
May I suggest that folk do their own experiment in either moist sand or mud to see exactly how a naked foot would leave an imprint.
Once the whole foot is lifted everything that is in front of it is kicked forward & not upward like a meteor crater.
and when a walker lift his feet high enough before the next step then not much is kicked forward
