After reading the reviews and having purchased several brands of running shoes, I decided to give these a try. After all it's Amazon and I could return them if they don't work out, right. I own the heavier Hurricane 12 that I didn't care for so i was skeptical. I've found I do best with either Asics or Saucony's. Having a lower arch, a slight flat foot and being a mild over-pronator I've found that I do best with shoes that provide cushioning for a comfortable ride, light weight and enough support to control the foots tracking on impact. I almost sent this shoe back when I first put them on because they were stiff and somewhat uncomfortable. I didn't really understand how some talk about a running shoes "break-in period" until I got these. After giving them a chance the first few runs were not the best. Fast forward after a few runs and I think they will be this years running shoe, mixed in with my Asics gel nimbus14. They have broken in nicely. The cushioning is good. Flexibility is nice. If you are not use to beefed up cushioning/support on the inner part of a running shoe this will take some time getting use to. This controls and supports over-pronation while running. They are helping my running, alone with my strength training. I am 5'9,195lbs and run 15-20 miles per week and strength train 2 days a week. They're best to support my outdoor running. My Asics gel nimbus 14's are better for my treadmill interval and tempo runs.
