Palau opens the way for a new type of snorkeling and swimming fin. In actual fact, it has been designed for two specific needs. The first was to have a foot pocket that could easily adapt to at least three or four consecutive sizes so that the same fin could be used by all the members of a family, or by a group of friends, without requiring an infinite number of sizes. The second need was that of guaranteeing extreme comfort and an easy fit even if this is a fin with a strap to be worn with bare feet. The result is a fin that is extraordinarily practical, that adapts to practically any foot and that allows for very quick fitting in any situation. The blade is made from a light yet responsive material that assures a kick that is fluid, effortless yet at the same time quite powerful. The strap has a strong ring on the upper part to allow reversal of the strap itself or to fix the fins to the body or the equipment.
