Lifeproof just released fré for the 5S, picked one up last Thursday and I'm so happy to have a lifeproof on my 5S. I can literally use it carelessly and never worry.
The cases for the 5 WILL work, however touch ID won't work because the home button will be covered. The fré for the 5S has a super thin plastic covering over the touch ID now, which allows it to be used.
