Two of the same footprints in the same direction, on darker sand so an igneous? area that was covered with flowing or washed water. The top is less distinct and the dirt at the front is in lumps which indicates the sand was damp, whilst the one at the bottom is quite distinct, but the loose sand indicates that some of the sand was dry.
I would suggest either the sand is damper at the top (so closer to the sea?) but that seems unlikely or the person on the top was running and that the one at the bottom was walking, but it had time to dry out and then collapse, so was made earlier. But it still doesn't add up.
Given they appear to be the same print, I'd go with someone walking/running up and down a beach, or perhaps footprints where people have been playing some game.
