Disclosed are flippers worn with shoes, including: a fin portion including a body worn on the front of a shin of a user and formed in a plate shape, and an instep seating portion formed to be cut upward from a center of a lower side of the body; one or more bands coupled to a side of the body in a direction perpendicular to a longitudinal direction of the body; and a pair of first fastening devices each coupled to both ends of the band to be fastened with each other.

One embodiment of improved swim fins consists of a right foot attachment (101) with an outer right blade (111) and an inner right blade (112) which is arranged such that it does not mechanically interfere with an inner left blade (113). The blades may include a pivot mechanism (220) that allows the blades to maintain an optimal angle of attack as the swimmer moves their legs up and down. In another embodiment, a right blade (1011) and a left blade (1013) are attached to the feet of a person who is propelled by the blades above the surface of the water as they pump their feet up and down, forming a human-powered hydrofoil. Other embodiments are described and shown.

A configurable wearable apparatus for water sports includes a boot and a fin pivotably attached to the boot. In a first configuration, the fin is oriented towards the toe portion of the boot. In a second configuration, the fin is oriented towards the heel portion of the boot. The fin can be attached to the boot by rods having first and second ends. The first end of each rod is attached to the fin and the second end of each rod is attached to a pivot point on the side of the boot. The second end of the rods can be releasably secured to the toe portion or to the heel portion of the boot with press-fit or friction-fit assemblies.

A disclosed diver fin includes a blade and a foot pocket, distinct from one another and releasably connected to one another by one or more rails extending from a leading edge of the blade to the foot pocket. The rails extend from either side of the foot pocket and extend parallel to one another at least partway along the length of the blade towards a trailing edge of the blade. Each rail includes two sections: a first rail section, extending from the leading edge of the blade and terminating in a free end, and a second rail section, extending from the foot pocket and terminating in a free end. The free end of one rail section includes a female recess, and the free end of the other rail section terminates in a male extension, slidably receivable in the female recess. The disclosed fin is reconfigurable to accommodate different diving conditions.

The present invention is retractable finned footwear comprising an outsole with retractable fins and a lever used to extend and retract the fins. One end of the fins is rotatably connected at back end of the outsole using fastener, while the other end is extended outside from front side of outsole. The fins can be secured at the bottom of the outsole, to facilitate the footwear suitable for walking on land. The fins can be extended from bottom of outsole by pulling the lever positioned at the back end of the outsole. The extended fins provide forward propulsive thrust to user wearing the footwear in water. After using in water, the lever can be pushed to align and secure the fins in line with the outsole. This facilitates the use of footwear both in water and land.

A swimming flipper (1) comprising a foot portion (2) and substantially flat blade portion (3) extending there from, said blade portion (3) having provided on each longitudinal side thereof at least two opposed rails (4/5) extending inwardly and at an angle equal to or less than 90 degrees to the plane of said blade portion (3), and said blade portion (3) having provided at least two ridges (7/8) preferably underneath the blade portion (3) extending longitudinally from the foot portion (2), said foot portion (2) having provided a one-piece strap (6), and said foot portion (2) having provided at least two fixed couplings (11/12) to engage and disengage with the corresponding and opposing couplings of another said flipper portion (1) to interlock and hold two flippers attached to each other.

Multi-purpose footwear includes a show sole, a shoe tongue and a shoe vamp provided as a portion of a shoe upper and a paddle mounted to be displaceable to a plurality of alternative and predetermined positions with respect to the footwear.

A mono-fin for swim training is disclosed. The mono-fin has two separated boot structures that from two separate foot cavities for holding feet with toes positioned in front regions of each of the boot structures and heels positioned at back regions of each of the boot structures. The mono-fin has a mono-fin structure with blades portions connecting the boot structure through the front regions of each of the boot structures. In a middle region of the mono-fin structure and between the blade portions, there is flex region. The flex region allows angles between the boot structures, distances between the back regions of the boot structures and angles between the blade portions to be changed simultaneously by a swimmer while swim training in an aquatic environment.

The invention relates to an aquatic shoe consisting of a shoe body (1), a pair of wings (3) and floats (4, 4), characterized in that the wings (3) are symmetrical, glued together, and linked to the shoe body (1), below the shoe, so as to constitute a part of the sole (2) of the shoe, and in that the float (4) is integrated below the wings (3), at the sole (2), so that one of its faces covers the sole (2), and in that the wings (3) are fixed by a pivot connection on both sides of the shoe, so that they descend when the foot ascends into the water and rise when the foot goes down into the water so that they return to their original position. The invention also relates to the use of footwear in the fields of recreational water and/or sport and in the paramedical fields. The shoe according to the invention can be used for the rehabilitation of animals.
