I bought these sandals last year and they completely unraveled upon the first wearing. I returned them and they reluctantly sent me another pair. I had a chance to wear the replacement pair for the first time this week, and the same thing happened. The pleated slide opened all the way up, I was just walking in my house, and I nearly fell holding a plate of food. Obviously something is very very wrong with this design, and after searching on this model shoe online I see that this has happened to other people. Customer service told me that you can only return a pair once! I am stuck with an unwearable $300 pair of sandals.
