When you right click with a piece of armor it will go in the wrong spot if the correct slot is already taken. (I.e Wearing gold boots. Right clicking with diamond boots. It places it in your leggings spot.) It gives armor bonuses for the slot it's placed in. Boots can be worn as pants for the same armor value as pants.
