I think that the best vapors to come out were the 5s. A total step up from the vapor 4s (in my opinion), they displayed more comfort and a more solid supported feel. The color-ways also were great. The first color-way was a bit shaky as usual. Then nike released the mesh and black shoe to satisfy everyone's craving for a black shoe after federer wore one in the 2007 Us Open (night matches only). Then came the actual Us Open vapor 5s (2008 Us open). this included a white and red show for day matches and white and beige for night matches (including the final). My opinion is that the beige vapor 5s were the best vapors released. I actually got lucky and copped one of the 50 sold within 4 hours of release at the Nike Us Open store!
