This is my 5th pair, and overall love them.  My only gripe is the shoes wear out in exactly the same place, every time.  They wear through after 6 to 9 months of daily wear.  With this consistent wear, it seams like Keen could do something from a manufacturing standpoint.

I love the way these flip flops feel.  They are as comfortable as any shoe, and stay perfectly in place on the foot.  My only gripe is how fast they wear out.
