## Abstract

A shoe with integrated fin apparatus including a pair of fin members disposed on either side of a shoe proximal the outsole of said shoe, each of said fin members including a maximum width disposed proximal the toe box of the shoe and a minimum width disposed proximal the heel of said shoe, wherein each of said pair of fin members is moveable between a furled position, securable to a shoe fastener medially disposed atop the toe box, and an unfurled position, disposed splayed laterally along each side of the shoe, whereby said shoe with integrated fin apparatus is wearable for unimpeded locomotion upon dry land and is also usable to effect increased water displacement when swimming.

## Claims

### Claim 1

A shoe with integrated fin apparatus comprising a pair of fin members disposed laterally upon said shoe, each of said pair of fin members disposed upon the shoe proximal an outsole of the shoe upon either side of a vamp of the shoe, each of said pair of fin members connected proximal a heel of the shoe, wherein each of the pair of fin members is connectable atop a toe box of the shoe when folded to a furled position and positional splayed laterally from the shoe when disconnected therefrom and moved to an unfurled position, whereby each of said pair of fin members may be furled when walking upon dry ground and each of the pair of fin members may be unfurled to displace water when swimming.

### Claim 2 (depends on 1)

The shoe with integrated fin apparatus of claim 1 wherein the shoe further comprises a drawstring disposed around a top line of the shoe whereby the shoe is adjustably securable around a wearer's ankle.

### Claim 3 (depends on 2)

The shoe with integrated fin apparatus of claim 2 wherein each of the pair of fin members is connectable atop the toe box and storable in the furled position by means of a fastener.

### Claim 4 (depends on 3)

The shoe with integrated fin apparatus of claim 3 wherein each of the pair of fin members is generally triangular in shape and converges from a maximum width proximal the toe box of the shoe to a minimum width proximal the heel of the shoe.

### Claim 5

A shoe with integrated fin apparatus for use walking on dry land and to assist swimming in aqueous environments, said shoe comprising:
a pair of fin members laterally disposed upon said shoe proximal an out sole of the shoe, each of said pair of fin members having a maximum width proximal a vamp of the shoe and a minimum width proximal a heel of the shoe, each of said pair of fin members moveable between a furled position, for walking upon dry ground, and an unfurled position, for use when swimming;
a fastener disposed upon each of the pair of fin members cornerwise at the maximum width, each of said fasteners connectable to a shoe fastener disposed atop a toe box of the shoe;
a drawstring disposed around a top line of the shoe, said drawstring adjustable to secure the top line around an ankle of a wearer;
wherein each of the pair of fin members is storable snugly around the shoe vamp and toe box when connected atop the toe box in the furled position for walking on dry land, and each of the pair of fin members is extendible laterally from the shoe when moved to the unfurled position for use when swimming.

### Claim 6

A shoe with integrated fin apparatus for use walking on dry land and to assist swimming in aqueous environments, said shoe comprising:
a pair of fin members laterally disposed upon said shoe along an upper edge disposed between an outsole and an upper of said shoe, each of said pair of fin members comprising:
a concave, arced edge disposed along a maximum width of the fin proximal a toe box of the shoe;
a long edge disposed bounding said fin member in parallel with the upper edge of the shoe, said long edge curving into a minimum width of said fin member proximal a heel of the shoe;
a corner disposed between the arced edge and the long edge;
an inside edge disposed connected to the upper edge of the shoe, said inside edge flexible enough to enable movement of said fin member between a furled position and an unfurled position;
a fastener disposed proximal the corner, said fastener connectable to a shoe fastener medially disposed atop the toe box of the shoe;
a drawstring disposed around a top line of the shoe, said drawstring adjustable to secure the top line around an ankle of a wearer;
wherein the fastener of each of the pair of fin members is connectable together and securable to the shoe fastener, whereby the pair of fin members is storable snugly around the shoe vamp and toe box when connected atop the toe box in the furled position for unimpeded locomotion on dry land, and each of the pair of fin members is extendible laterally from the shoe when moved to the unfurled position for use when swimming.
