It is their crisis there and the flippers stick together. And with us - they stack up, because everything is fine and vacation is on the nose.
Despite some curiosity, the invention of the designer Edward Shelton (Edward Shelton), it seems to me, will find its fans. The point is that in the Amphibian set, rubber shoes are attached to the fins, just like boots are attached to skis. The flippers themselves are folded for convenience. Total: no need to think where to put an extra set of shoes, and you can not go ashore at all where you entered the water. In general, it is useful for rescuers and vacationers. ')
