I would suggest that you get firts your front foot in the straps. This gives a natural stance. The back foot is placed in between the front and back straps, along the the center line of the board. When you feel a bit of acceleration you get in the back strap. More skills you have faster you can do it. Th eother way around is out of my view harder due to the fact that the stance is super wider and you give the board the chance to turn upwind or into the wind.
