If your toes stick over the edge a bit, thats all right. I ride a '07 Rome Machine 157 (wide) w/ '07 Libertines, and my toes stick out just a bit. This is fine, as my bindings ('07 Targas) raise my foot high enough off the board that I would need to lean over ridiculously far to even skim the snow. Almost all riders have a bit of toe hang, big footed or not. And don't use risers, they're terrible.
