I contacted the makers of FitFlop asking why I can't find this particular slingback anymore.  I was told "it is a very OLD model and has been discontinued" ...having owned several different styles of FitFlops, I was very disappointed to learn this, since the slingback with toe grip was THE BEST and most SECURE fitting sandal FitFlop makes.  Why would they discontinue it??

Perhaps if enough of us complain, they'll make this model available again.  Fingers crossed.
