I first got a pair of these sandals at a clothing swap. They were the most comfortable shoes I think I have ever worn. I have now purchased them in two other colors.
When I put them on, they felt wonderful. Then I noticed something: The heel strap falls just a tad too low, enough to drive me nuts when I walk in them. Disappointed, I ordered another style - same problem. So a huge disappointment. The only sandal I've bought that has a heel strap that falls that low, feels constantly nagging. Had to return both pairs and SO disappointed.
Overall I love these sandals, which is why I bought a second pair when my first finally fell apart. Imagine my surprise when the sandals that arrived were too small despite being the same listed size as the old pair! (It's not that my feet grew - I measured the sandals themselves and the new ones were smaller.) However, I was pretty easily able to exchange them for a half-size bigger which fit perfectly and I am happy with them now.
