I have seen some ads on this shoe saying AdiZero Rose 2 Windy City and some ads saying Adizero Rose 2.0 Windy City. Is there any difference between the 2 and 2.0 or is it the same shoe. I see some photographed with blue laces and some with black laces. Do you get both when you purchase them. I see EastBay is going to sell them and taking preorders now.
