Hi guys, I'm currently using a Barricade 6 that is giving me blisters and leg pain. I don't really like the Barricades, so buying a 7.0 is out of question. Apart from comfort, I'm really looking for fast shoes. Up to now I've tried (on stores) the CB 4.3, which I really liked (I felt that I could reach any ball, like Nadal), as well as the Asics GR4, that I found fantastic but not did fit perfectly in any size. Also tested the Vapor 9, I did like it, although I didn't think it was fantastic. The main factor that appeals to me so much in the Vapor 9 is that Federer uses it. So I'm taking great care choosing my next pair of shoes, since here in Brazil a Vapor 9 costs as much as 215 dollars, so buying more than one pair is impossible. I need durable shoes, that can last 5 days a week of playing, 4 hours a day. Thank you very much for the help!
