By no means would I ever consider myself a runner; however, i do cardio 5 times a week alternating between elliptical, treadmill and spinning bike.  I need a solid training shoe to add to my normal shoe rotation of Nike Free and Asics TR-150's. I've been searching for weeks for a new pair. I wanted a lightweight shoe with good support and cushioning and found the ignition 2 @ a local store on sale for $50 plus I had a coupon for 30% off which brought the price down to $35.  I tried several different shoes including the high end Asics, the K Swiss Tubes, and the Nike Fusion TR's but kept coming back to these because of the comfort.  I won't lie, the price tag was also attractive and made this by far a much better value.  I've had these for 2 weeks now and find myself using these shoes more often than the others when I head off to the gym.  I like the cushioning and comfort.  On the treadmill, I find no significant difference between these and my other shoes with the exception that these are softer.  I highly recommend if you need a decent all around training shoe for the gym.
