Traveling to the Caribean you always take the chance of ending up at a beach with a rocky bottom, or just around the pool having to walk out on the blistering hot concrete.  The solution, water shoes.  The problems with water shores are they can be difficult to put on or remove.  Speedo solved these problems by putting a zipper on the top of the shoe.  The zipper is of good quality and makes putting on and taking off the shoes a breeze.  Great idea!
