Boots may not get over the edges. I "tested" that myself, and I still feel the consequences.

So, let's immagine the board laying down on its bindings, like the opposite of what it lays down on the piste. With boots attached. Looking down at it:
- I shouldn't see the boots at all?
- I could seee the boots, but not the heels?
I mean, how much away from the edges do the boots have to be? Right in the line with edges? 1 cm to the inside? 2 cm? 'Cos, if they don't go over the edge, when you put the board at 75* (for example), boots WILL touch the snow underneath!
Or am I (again) missing something?
