I've started running again after a 4 month hiatus, and these were the shoes I bought to replace my ancient New Balance cross-trainers. To illustrate how aweesome these shoes are, I ran in my cross trainers and did about 2 miles at 11 min per mile. The next day I slipped these on and brought it down to 9:45! They are incrediblty light, fit well, and gives a nice extra spring in your step that makes running feel easier. You can feel the plate in the sole really support the arch of your foot and push you to keep going.
