Gussets til about ankle height-second "X" of white laces from the bottom. I think the whole tongue will stay well in place as the white laces cross through a piece sewn to the tongue right where the red laces start. Cinches all together tightly.
They do, but it doesn't extend the full tongue. I'd say the gusset goes little less than half way up the boot.
They do down by the foot and at the ankle, but not as the boot goes up to the calf
