ABSTRACT:
An amphibious shoe has a sole with a fin compartment therein. The fin compartment provides retractable housing for a lightweight fin for conversion from a walking to swimming shoe. In one embodiment the amphibious shoe includes a fin comprising a plurality of ridges. The ridges are intermittently disposed between material arranged in an accordion construction. When ejected from the compartment, the ridged material expands to a fan configuration. The fan is further appointed with a pivotal stabilizing strap for enhanced stability during swimming. In another embodiment the amphibious shoe includes at least two fin plates pivotally attached about an axis. The fin plates are stowed in an overlapping condition. They are capable of being ejected from the compartment and opposingly rotated toward the front of the shoe abutting to form a swim fin. In operation, the wearer can comfortably run or walk swiftly along the land as the integrated fin has a thin lightweight construction. Upon reaching the water's edge, the shoe is readily converted for swimming by ejecting and positioning the fin.
