No problem with the CB4.3 except that they don't quite lock my foot in securely enough. It's bearable when hitting but when I'm really playing hard I don't feel safe changing direction hard. I wear two layers of socks and ankle braces and play competitively for a University. They last forever though, mine have white splotches all over (the outsole has been worn out thoroughly), yet there is still no sign of a hole. They last so long that eventually you'll start unintentionally slipping around the court because the tread is gone. I'm now on the Vapor 9s which last no where near as long but the secure fit allows me to move efficiently and slide when I want to.
It is not the mountain we conquer but ourselves.
