Moccasins

Moccasins would be another feature in the Plains and Prairies update (I hope Mojang will approve) and can be crafted with 2 leather 2 feathers and one string. They would make you completely undetectable to mobs until 5 blocks away, and would be the equivalent of sneaking. It would really boost stealth combat because you could kill a mob without it even realizing what hit it!
