This is a device that allows players to run up one-block high staircases much like horses do. It was inspired by the Boots of the Traveller from Thaumcraft.

It works by naming any type of boots (enchanted or otherwise) "Boots of the Traveller" and equipping them.

It is confirmed to work in singleplayer, and while logically it should work in multiplayer, it hasn't been tested, so any conformation to that effect would be great!
