A pair of Flip-Fins  by Omega Aquatics,  A natural evolution within the dive industry, the Amphibian™ fin system is designed to be strapped on prior to entering the water and removed after exiting. The heavy-duty springs push the soft blade webbing up to ride gently against the shin while on the surface. This makes walking, climbing boat ladders and other movements as easy as wearing no fins at all. Once in the water, The Amphibian™ blades are flipped down into swimming position by simply kicking naturally in the water, and flipped back up by pushing back on the release levers before getting out.
