Watching the Monte Carlo Masters, I've noticed that quite a few of the guys (e.g. Melzer, Simon, Gulbis) are still using their Adidas CC Feather IV. Chances are they love the sole for the extra traction on dirt, because they're like indoor soccer spikes. Is there any chance that there's still old stock of these models? Or will Adidas offer a version of the AdiZero Feather with the same sole pattern?
