I run 20 - 30 miles per week and the occasional half marathon. I am 5''9" and about 150 pounds and I run +/- 9 minute miles, in case that helps with your evaluation. This is my second pair of the Saucony Powergrid Cortanas. I like the combination of light weight and support. My first pair lasted about 600 miles - in fact, I probably waited a bit too long, the impact point is worn completely flat. But they are very comfortable to me and I have had no foot or leg problems (knock wood) since using them.
