This is not my first pair of Teva's.  At first I balked since I was used to flip-flops costing but a few dollars, but my already bad back was suffering.  I could live in flip flops year round, but needed something a little more polished and a little more supportive.  The strap system took a day or two to get used to, but now I can't even feel them, and they actually prevent your foot from sliding around.  The thicker than usual bottom also provides nice support and makes wearing them and walking for long periods quite comfy.  I am slowly getting rid of all my non-Teva flip flops and replacing them with these beauties.  Not only are they the most comfy flip flop I have ever worn, they look dressier than most as well.  And...they don't flop around like a standard flip flop.  Love!
