Abstract: A diving flipper is provided wherein a blade is attached to a body 1, which is secured to a foot, so that the position of the blade can be switched between a position for use and a folded position. The folded position is attained by rotating the blade about an axis in a base, or at a front of the body. This flipper can be used for swimming in the same manner as a conventional flipper when the blade is in the position for use, and the user can easily climb a ladder of a boat or walk without the blade causing interference when the blade is switched to the folded position.

Abstract: A diving flipper is provided wherein a blade 2 is attached to a body 1, which is secured to a foot, so that the position of the blade 2 can be switched between a position for use and a folded up position having the center of rotation in the base, or at the front, of the body 1. These flippers can be used for swimming in the same manner as conventional flippers when the blades are in the position for use and the user can easily climb the ladder of a boat or walk without the blades causing interference when they are switched to the folded up position.
