A flotation device is provided for enabling a person to stride upon a body of water. The device, to be worn on each foot of the user, is comprised of a series of horizontally elongated parallel keels, and flaps pivotably suspended from the keels. When downward force is applied to the device in the water, the flaps pivot upwardly to form roofs of channels between adjacent keels. When the device is lifted from the water, the flaps swing downwardly, thereby breaking any suction effect which would cause retention of water within the channel. Such mode of operation improves the ease with which the device is lifted from the water in walking or skating motion.
