REEFS SUCK, LOOK AT MY PIC.  Took a pair of Reef's to Costa Rica.  Everytime they got wet in the ocean the straps left huge black marks on my feet.  This wasn't like a one time thing.  EVERY TIME THEY GOT WET.  Complete garbage for an expensive pair of sandals.  It looked like I had a crazy foot disease.  An it was hard to wash off.  Anyways, I threw the reefs in the trash where they belong and got myself a pair of Kustoms.  Cheaper, lighter, more comfortable and NO MORE BLACK FEET.  I put up a picture of my stained black feet.  REEFS SUCK!  Oh and you look like a jack@$$ using a sandal to open your beer.
