When you get close step putting your toe down first then followed by your heel with a tapping motion sounds just like a four legged animal walking can fool deer into thinking youre just one of them, picked up this bit from reading Fred Asbell's book on stalking and still hunting. Used it in Cap forest on frozen roads could hear deer approach but never saw em in late bow season, blacktails like to spy on ya from the thicklies before committing. Kinda goofy but effective.
