It's the toe height.  The jester's/griffons have automatic toe height adjustment, but the system's been less than perfect for marker this year. Basically the binding doesn't clamp down too well vertically on the toe of the boot.  Apparently it's one thing marker's tried to fix for next season.  I haven't experienced this, only read and heard about it.  There's someting about the idea of a 16 DIN plastic binding, it just doesn't make sense.
