I've been playing tennis for over 40 years. It is the best shoe I've ever worn.
After wearing the vapor line for at least nine years due to the low ride, weight, and superior aesthetic/function characteristics, I confidently proclaim the Vapor Nines the best yet, with the clay version at the pinnacle. You truly feel the court with these like no others. The out of box comfort is insane, not to mention the outer sole pattern that gives increased contact area for precision sliding and directional recovery. Please Nike: give us more Color schemes on this model!
A very unique pattern on the sole of the shoe gives any "clay court specialists", or anyone else who wants to play on clay a distinct advantage in the footwork department.
