I really need a pair of shoes for my basketball games and for games. My shoe size is a 10.5-11.0. I need something that can improve my performance, run faster, and can grip the floor better. I currently have a Nike Pegasus running shoe. I wanted a basketball one, but couldn't find one. The shoe has been making me slide up and down the floor. Could any one of you give me a reply and maybe an attachment? THX!
