I bought these flip flops because they looked nice.  Only after I ordered them did I realize there were bottle openers built into the soles.  How cool is that?!?!  When they arrived, I had to put them on and pop open a beer.  It worked like a champ!  I haven't worn flip flops in a very long time, so my between-the-toes weren't used to the leather strap.  I'm hoping the leather softens up and my tween-the-toes toughen up so the discomfort goes away.  The soles are very comforatble.  I would definately recommend these nice looking beer popping flippety flops.

Update: March 2015: I just bought my second pair.  The first pair lasted three years of constant summertime wear.  I ended up pulling one of the straps out.  They aren't made for heavy duty yard work and digging. LOL.  Other than that, the rest of the sandal was fully intact and in good shape.  I do believe I will always have a pair of these Reef Sandals.  Oh, and the leather between the toes did soften up.  Or my skin hardened because I did not have the same "issue" with the new pair.
