Whats the difference between the adidas F50 adizero prime soccer boot and the adidas F50+ soccer boot?

I am interested in buying my next boot but I am not sure which one I would want. I love the adidas F50 family and I want to stay in it. I have a lot of information about the F50 adizero prime but I can't find anything about the F50+? Any information about the boot is helpful.|||Nothing much just the look
