text: Amazon asked me to do this review so I am. I ran on then three times. They're light and my feet don't hurt. I have no idea whether they are good for a long run, or over the long run, or even whether they are as good as my Synchro 2's that I used to run on. But Amazon called and I answered. Kind of useless to review them with under 15 miles on them, but there you are.
