I love these shoes for the most part.  They are comfortable, they don't hurt my feet when I wear them a lot, and they are the only shoes that I can wear with a bone spur in my heel.  That being said, within a couple of weeks of buying these shoes, the fabric on the inside where your heel slides in started to tear.  Now, a little over 6 months later, the padding in that area is gouged out.  It doesn't hurt or anything, but I expected more out of a pair of shoes that I paid $100 for.  Maybe I just got a bad pair.  I'm going to try one more of the Zigs and see how it goes.
