This footgear only had a single layer of soft hide that allowed toe tips and bones in the foot to leave
impressions in the soil. There had to be some kind of toe guard wrapped around the front of the foot to make the displaced piece from between the big and little toes with the stitching pattern at the top, the parabolic ridge, and a notch from the webbing between the toes of the ape-like foot. This would be like stepping on a flat piece of aluminum foil laid on a folded bath towel with a bare foot. All of the features of the bottom of  the foot will be transferred to the towel. The difference is that there would be casts of the foot’s shape not a  cast of a shoe sole if the depression were filled with plaster.  
          This foot appears more like that of an Australopithecus with its fully abductable hallux.
