ABSTRACT:
An apparatus for aid in swimming is described as including a foot receiving portion that is pivotally attached about an axis to a fin portion. A latch mechanism is attached to the fin portion that cooperates with a tapered nose protrusion that is attached to the front of the foot portion. A pair of forward stops are provided in the foot portion which cooperate with a pair of recesses that are formed in the fin portion which together limit the pivotal motion of the fin portion in a first direction until a first position is attained. The tapered nose protrusion cooperates with the latch mechanism in the first position to secure the fin portion in the first position. The latch mechanism includes a release to allow for the manual disengagement of the latch mechanism from the foot portion which, in turn, allows the fin portion to pivot in a second direction that is opposite the first direction until a second position is attained that is disposed approximately opposite the first position. The first position is adapted for swimming and the second position is adapted for walking. A heel strap secures the foot of the user in the foot receiving portion during use.
