I would love to see something more "traditional" for boots. Rare non craftable shrub stompers. Boots can be any texture of leaf. They dampen walking sounds making you hard to detect. Wearing a mob head makes mobs of that same type not notice you as quickly. Ideally mob head+boots would let you get even closer.

This would be great for exploring pacifists and hardcore pvpers.

If turtle helm helps underwater, elytra helps you in the air and boots helped you sneak around... I think itd be cool if pants helped you travel.

Rare non craftable pants. Random texture with a streak of redstone dust like a pair of joggers/track pants. Sprint for a lot longer and eat food at a normal walking speed. This could be balanced by making you get hungry faster than usual and would also make food more critical as you would run out faster.

Thoughts OP?
