First, I LOVE THE COLORS!!!! When I put the shoe on, I was so amazed at how much lighter these felt compare to the Adrenaline 10 shoe and how much more cushioned they were. I LOVED them!!! I still do really like them but now that I have ran in them about a month, or two, I am beginning to have the same problem I did w/ my other ones. The tongue on the right shoe won't stay put and begins to hurt the top of my foot. I have them looped correctly, tried tightening them, tried loosening them; nothing helps. Other than that I love them, so I hope that Brooks can come up w/ a way to stop that.
