Disclaimer:  I'm a bit ocd about things lining up & "matching."

The rows of clear stones were misaligned on the first pair I received.  However much this bothered me, I tried to ignore it because they are so pretty.  Unfortunately, I couldn't get past it.  Amazon was great about sending a new pair out right away.  The second pair looks great.  It feels as though there's something poking the ball of my foot (like there's something inside the sole), but it's not enough of a pain for me to return them a second time.
