I'm no running expert at all, but they look pretty cool like they all do. One thing I can advise, is to work yourself into lighter shoes slowly and not jump into a light barefoot type running shoe from a thicker sole heavy shoe. My original shoes I started running in were around 16 ounces or more, then I tried the lighter 890s at 12 ounces I think, after a few years of plodding along. Now the shoes I just ran in a half hour ago pictured above are 9 ounces, and you definitely feel it.
They feel very light, as if you are barefoot, but with something on the bottom of your feet for rocks and shit. I know my running style has changed quite a bit, and if I tried running in these a few years ago I would be hurtin'. I used to run like a runningback, all muscle, strong leg strides, and serious impact on the pavement. I am now trying to increase my cadence and run lighter on my feet. It is definitely working based on my pace so far, and I can run longer distances like that too.
I guess what I'm trying to say, is to experiment a little with new shoes when you need them, and go in with the expectation of tossing a hundo out the window if you don't like them. If you think you can assess if you like them pretty quickly, hit a running store and they will let you try them on and run on a 'mill with them to get an idea of how they feel. And then buy them from them! Support your dealers!
Post up what you get and how you like them.
