ABSTRACT:
Amphibious shoes which may be used as walking shoes with easy convertibility to swim fins. The amphibious shoes of the present invention comprise a shoe-like structure and a one-piece continuous sole-fin structure affixed to the shoe-like structure. The one-piece continuous sole-fin structure comprises a fin-like extension integrally fused to a sole portion of the shoe-like structure and a flexible folding zone, thereby facilitating the easy movement of the fin-like extension for engaging with the shoe-like structure. The fin-like extension folds upward and is secured to the shoe-like structure in the walking mode and unfolds with minimal manipulation for swimming without the need for mechanical pivoting or locking devices. The fin-like extension has a length not exceeding the distance to the user's ankle when secured in the walking mode thereby allowing for unencumbered walking but still providing ample surface area for increased propulsion during swimming.
