Heel and sole edge have been stained transparently to show-off the various layers of leather in the heel. (The alternative would be a heavy, opaque layer of paint that covers everything.) I presume that mark might be some minor damage when the display model was rubbing against something. It is also possible that the leather did take the stain differently.Whatever it might be, the heel can be easily re-finished.
