Did the Boost feel bouncy right when you put them on your feet, or did you have to run and play in them for a little bit before the bounce showed up? I think that's where, perhaps, we are all getting confused. In the reviews, they make it sound like right when you put the shoe on you know RIGHT AWAY the Boost is bouncy, Ultraboost-like, etc. I'm fine with having to break them in or whatever, it has just been very misleading because people keep mentioning how great the Boost is and then some of us go and try the shoe on and they feel like rocks.
Not to mention the fact that I've had a very inconsistent experience with Boost in 4 different Rose 6 shoes. Some felt neutral (like nothing, perhaps a slight bounce), some felt very bouncy and soft and plus, some felt bouncy at first and then hardened up 2 months later (like my current pair). Others are saying they're still playing in their Rose 6 and it's still bouncy (maybe not as much as before, but not HARD at least like my pair), so I am just afraid of Boost now.
