I'm looking for a decent running shoes for morning exercise. I've tried every shoes I own but none of them really seem to fit strictly for running. Jordans are too fresh, Air Force/Max are my casual wear, and some are just downright uncomfortable. I need some opinions from people who owns actual running shoes since I've never had one. What shoes do you own? Is Nike+ considered the best? Is there really a difference between a $100 and $150 shoes? etc etc..
