Which running shoe should i get? they are Puma Cell Flexion Black and the NIKE Air Zoom Katana Cage III?

In all honesty I wouldn't recommend running in either one of those shoes. If you are a casual runner you will be ok but if plan on running some serious miles, it would be smart to invest your dollar in another shoe. Go to runners world web site they have a great shoe calculator that will tell what shoe is good for your body type.
