I own the Nike Structure Triax 15's....and just passed the 300 mile mark with them. They are starting to lose their cushioning/responsiveness...is this normal?
Here is a photo of the shoe:

I'd like to hear what others have gotten out of these shoes. I'm run primarily on the roads and can usually get 600 miles out of the Lunarglides and Pegasus.
