I was never a big fan of flipflops - until now.  These Reef Fanning's are very comfortable - I wear them daily and are my footwear of choice.  They are durable - I tromp everywhere with them - shopping/around town/chores around the house and yard - and of course, to the beach.  Never had a need for the bottle opener, but if I knew about these "back in the day", I'd have worn out the opener.  First pair still going strong after two years of hard use - starting to get a bit ratty, so buying my second pair, and surely not my last...
