There aren't any boot drops? I saw some mobs wearing boots, but they had helmets on their feet.
Will test more, but after a few inventories of /dd, I never saw any.

I can confirm this and am going to take a look now.

It's entirely possible for boots to be spawned into your inventory with the "/dd" command. I still haven't found a mob that actually dropped its boots, however.

They drop with the current code. Original issue was setEquipment method.
