I had and loved an earlier version of this shoe. After having my stride evaluated, I was told I needed a neutral running shoe, possibly with a bit of support for my tendency to underpronate one foot. I ended up with the Brooks Ravenna, which does seem to provide the support I need. It's not a very cushioned shoe though, so I've also been running in the Asics Gel Nimbus 13, which is almost like a giant pillow. The Asics Speedstar does what the Nimbus does--provide cushioning and a little support--in a much lighter package. I've done 4 miles at a time in these so far and never had issues with shin splints or sore knees. If you're a neutral runner in need of a lightweight shoe, this is definitely one to consider.
