After ordering/returning this item twice, I was told that the wrong picture was being used for this purchase.  Either the picture was not corrected, or the item they are shipping has been corrected.  So, just a warning for those looking for a heel strap.  By the time the second one arrive, we were desperate for a flip flop for some things/trips we were doing.  Without a strap, this is a very comfortable flip-flop for my 4yo, with a great arch support.
