Ok, so I have had these on for the past hour and all I can think about is what I'm going to say when I write the Amazon review--especially since I do not often write reviews.  So, these shoes are saying to me, "I have your back on the arch . . . I'm here when you need me."  I have tried on 14 pairs of flip flops over the past two weeks and these sealed the deal.  The others (Including Nike, Sketchers and Dockers) had inside straps that rubbed on my insole.  These are comfortably snug around the top of my feet (the others were always loose). These shoes have a very supportive heel that can support me leaning back on them.  The other shoes either forced too much of a high arch for my foot or they had this annoying raised line at the toe.  Finally, I tried the Reefs only to learn my first pair had this bottle opener on the bottom.  Really??  First, I don't drink.  Secondly, the whole bottle opener area seems like it will just pack in dirt that would end up on my kitchen floor.  THANK YOU Reef for making a fantastically comfortable, snug, sole supportive and remarkably cushion-ey pair of flip flops that can be worn in the back yard, at the beach, or about town.  I'm hooked!!
