with rossi bindings the forward pressure is determined by where the little black line falls on the window on the heelpiece.
op, look at the heelpiece of the binding from the side with the boot clipped it. you should see a neon green area and possibly a black line. use the tab on the bottom of the back of the heelpiece to move it forward on the track, then clip the boot in again, keep doing this until the black line on the neon green in the window thing is near the middle of the window opening.
