I bought a black pair in store and am in love with it, but its not my favorite color.  So, I bought on Amazon, but theres huge difference in comfort: no arch support as the black pair; the thong is tighter and kind of bend into the foot, very uncomfortable, and I have thin feet.  I cant imagine people with thick feet!  Though I like its colors and the sole is soft and pleasant.  Too bad!  I want to love it so much.  Have to return.
