I'm on the lookout for new shoes because my barricade IV's are starting to rip up and lose cushioning. I'm really interested in trying out the nike Breathe line. I've heard good things about them, especially the Breathe Free II's and the Cages. I'm not sure which one to get though. I'm leaning towards the BF2's because they're cheaper and I don't really like the colors that are out for the Cages now. Can someone compare both of them? Especially the durability issues. Also, should I get the same size as I wear with my barricade IV's? Or should I just stick with the Barricade IV's? Or maybe wait until the Barricade V's? Thanks.
