Abstract
Abstract The improvement provided by this invention is directed at the conventional beach-shoe and diving flipper, and according to this invention, a novel beach-shoe capable of acting as a diving flipper is provided. The web portion is extensible relative to a shoe body, the shoe can be used as a beach-shoe when a web member is received in a recess of the shoe body, and a guarding piece is placed in a cut-out made in the front end of the shoe body to admit the web member to pass through. The shoe body comprises a platform including peripheral walls, the opposite side portions of the peripheral walls are formed with inside guiding grooves, the front portion and rear portion are respectively formed with a cut-out, the two cut-outs have identical shape which corresponds to the shape of a guard piece, so that a guard piece can be placed in alternative cut-out, when placed in the cut-out of the front portion, the web member can be restricted in the recess, and it should be removed therefrom to place in the cut-out of the rear portion when the web member is desired to be pulled into a stretched position.
