I say learn to ride with a slight duck stance. I'd recommend starting with 15/-9 then you can slightly change them each time out to see what your preference is
I agree this is a good starting point.
Let me try and help you as well. Angle diagram: Print it out and have fun. 0° is measured from heel to toe. So a deviation of that "foot across the board" "|" angle 0° would be, slanted like a \ a positive angle, and / a negative angle.
\ is a positive angle on the front foot - / is the same negative angle on the back foot. ***\*****/***
| is a 0° angle. Many beginners start out close to this. It would look like: ***\****|***
Try wearing socks and running and the sliding across a hardwood floor skate board style sideways, duh...
. When you come to a stop, see what angles your feet are. Adjust bindings to that, its your natural posture.
For every 2 hours you ride regular, to 30 minutes fakie. You will thank me later. Many people can ride "well" regular, but when they try fakie they almost start over again. So practce both direction now! It will also help your overall skill to improve much faster.
