Abstract: An aquatic accessory adapted for frictional attachment with a shoe being worn by a user comprises a receptacle portion and a fin portion extending outwardly from the receptacle portion. The receptacle portion is adapted to receive at least a portion of an inserted shoe, and frictionally attach with the shoe. Gripping members can be configured and angled in a manner for providing increased frictional attachment between the aquatic accessory and inserted shoe. The accessory can be fabricated from a stretchable material to provide a radial attachment force for enhancing frictional attachment between the aquatic accessory and an inserted shoe.

Abstract: An apparatus includes an upper portion, a sole and a fin. The upper portion is configured to at least partially cover a foot. The sole is coupled to the upper portion and defines a cavity. The fin has a first portion and a second portion. The fin is movable between a first configuration and a second configuration. When in the first configuration, the fin is substantially within the cavity defined by the sole, and the first portion of the fin at least partially overlaps the second portion of the fin. When in the second configuration, the fin extends substantially outside the cavity defined by the sole.
