I'm not much of a runner or running shoe wearer as much now days that I'm out of high school and sports every day, but.. I do say.

Pros:

These are so lightweight, I could not believe the weight of them when I held them up. It was like holding two of those big car wash sponges, you know, them yellow ones styrofoam? Anyways, these shoes also feel very comfy. It is like wearing nothing on your feet, but that feeling is the feeling of great support from the shoe and the ventilation. I cant describe it, its like I could feel the air hit my socks. I'm wearing Puma running socks right now and they're pretty tight on my feet, so air and water getting through these are hard, and I could feel the cool-ish air in the shoe.

But really, they are very light shoes, I love them.

Cons:

I can't say, I haven't jogged in them or sprinted, but the last pair of shoes I owned, they felt nothing like this.  They seem very durable though if treated right, these aren't for a kid to run around in and kick a soccer ball with and toe peg kick a ball or anything.  These are to nice to treat like street shoes, treat them as running shoes like I will be as I am just beginning to run again.

These shoes are my most comfy pair I own too by the way and I own Nike Air Forces, DC Skate shoes, Airwalk slip ons, none of these feel good like this shoe does.
