I have been curious to try the Nike Free's out lately, since I have never tried anything like it before. Now, I know that the 3.0/5.0/7.0 just means that the lower the number is, the closer it'll feel like "running on barefoot" and the higher the number, the more support the shoes will have. What I don't know is that the new Nike Free Run+ does not have a number associated with it. Is it closer to running barefooted or does it have a lot of support? Is there info on what number it would most be like?
