<p>An amphibious shoe-like structure (8) for swimming and walking having a shoe-like structure (10) for receiving a foot and a fin structure (12) that provides a fin blade surface that expands in the swimming mode and collapses in the walking mode to rest adjacent to the wearer's instep. The fin structure (12) comprises a plurality of fin arms (22) pivotally connected to the shoe-like structure (10) for rotating the fin arms (22) outwardly in the swimming mode position and for rotating the fin arms (22) inwardly towards the instep of the wearer for a walking mode position. The fin arms (22) diverge relative to one another when rotating outwardly and converge towards one another when rotating inwardly to rest adjacent to the wearer's instep. The fin structure (12) further comprises a flexible web member (24) that engages with the fin arms (22) and is of the configuration and size to accomodate the area generated by the expanding and diverging side fin arms (22). The convertible amphibious structure further provides for locking means (36) to lock the fin structure (12) in the extended swimming mode positions and for unlocking when converting into the walking mode position.</p> |
