I'm really disappointed in these.  I love Born Shoes - this is probably my favorite brand of shoe.  And after just very sporadic wear, these sandals broke.  The thong piece came out and was no longer attached.  It happened while i was walking, too, and I nearly sprained an ankle.

Update:  I spoke with Amazon and since these sandals are out of the return window, there are no refunds or exchanges for this item.  I've never had a problem with the quality of Born shoes before, and these hadn't even been worn frequently (seasonal nature of item).
