Right now I am wearing the Nike Breathe Free II's but just after a little over a year now I am forced to get new ones because on the bottom of the right shoe where my big toe is, I am getting a hole. I am looking at either the Nike Vapor IV's or the Adidas A3 Accelerators. Any tips or suggestions? I have a narrow foot and really like light shoes. The ones I have now are real light which I love but I want them to last I guess of course too. I had Adidas Responses before the Breathe Free II's. Edit: Also just noticed the Nike Air Max Breathe Cage shoes as well. Are they supposed to be a spinoff of the Breathe Free II's?
