Can anyone give some comparisons between these two shoes? As I think I want to get a pair of the adidas and I'm wearing the Vapors right now. I've worn the Barricades as well (IV's) and the replacement pair they sent me was defective so I'm probably going to buy the a3's with the coupon. So if anyone can compare fit and such it would be very useful. PS. Does anyone know when adidas is updating their store with the newer colors?
