I think he is asking what we all are wondering is what the heck is going on here. lol
Well, I see basic knee armour. The rest downward is all leather upper the is tied to the boot in some way.
*edit
Also on close inspection of pics, the Knee armour is attached to the leather band/pouch section near the top,
Leather band with pouch, soft leather section that has a small shin section that has leather covering it, then pleated sections of a soft leather also.
Is this one section or several that piece together?
