Looks the same as the Soft Boots. Rumours say you will be able to walk on water with them or walk with normal speed when underwater, however, most people believe it's not possible. Also some think it's just a "joke" or "decoration" from CIP. They can be seen under the Serpentine Tower in Ankrahmun under the room with the Fire Elemental, Vampire and Behemoth. Be careful as the Fire Elemental on the -1 floor or the Green Djinn on the -2 can be let out. You can see a screenshoot in here.
