Mizugumo (mud shoes)

A well-known tool of the ninja. Unlike a water moat or dry moat, a swamp moat surrounding a castle utilizing a natural mire permits neither walking nor swimming, making crossing it more difficult.

By wearing the mizugumo, a ninja’s weight is distributed to a wider area so that he could walk on mud, not on water although there is a general misunderstanding that the mizugumo allowed them to walk on water.
