LOVE the Reef Fanning Flip Flop!  SOOOOO Comfortable and SOOOO much suport.  I have a very high arch and these flips flops fill it well....unlike cheap/flat/slippery ones.  The grip on the bottom is awesome.....no slidding around the pool deck.  Not sure who would actually use the bottle opener??  Kind of gross to put a bottle to your lips after opening it with the bottom of your shoe!  I'm a tad disappointed in the pink.....it's more of a mauve and a bit dull, but oh well.  Love the shoe anyway!!!!!!  This is my second pair and I will be buying more, as I see the price drop.  $50 is kind of pricey.....but then again, you do get what you pay for.
