Because toeside and heelside are terms from skate, wake or snow boarding in which the feet are aligned differently it becomes confusing when the feet are lined up in the same direction as the edges. So picture riding on a trick ski with your rear foot turned out. I am LFF, if I were making a turn around 1,3,5 the ski would be on the edge closest to my rear heel this would also be my goodside. When I make a turn around 2,4,6 I make the turn on the edge closest to my rear toes so this would be toeside but also my offside.
