I love O'Neill flip flops (never liked flipflops before I stumbled across a pair, and now I wear them constantly), and mine were getting worn out (besides the uppers having been chewed on by my dog at some point when I was sleeping).  Tried to find an equivalent pair, couldn't (that model is no longer in production), so I contacted O'Neill customer support and sent them photos of my sandals.  The rep was amazing, and told me all about the materials in it, then told me which current model most closely matched my old sandals.  I bought the Superfreak immediately.  I was happy in them...until I sat down.<br />Know how your sandals bend a bit when you sit with your heels on the floor and your toes NOT on the floor?  Makes it so the back edge of the sandal rests against your heel?  If you drive in flipflops, you know this process better than most.<br />That's a problem with these.  See that hard plastic barrier around the edge of the footbed?  It is incredibly uncomfortable to have it pressed up into your heel.  Painful, even.<br />I'll be picking up a pair of Phluff Daddies next; they don't have that border wall, and O'Neill is still the best thing that's ever happened to my feet.  Hopefully, they last as many years and bring me as much comfort as my old beat up...whatever model they are...which I'm wearing as I write this review.
