Hi there,
I am new to VFFs, currently running on the Komodos LS (my first pair of VFF) and I am already sold in this barefoot movement.

I was running an avg, of 12km perd day 3 to 4 times a week. Now I have cut it down to 5km with the VFF, and boy do I really feel the workout producing results, much more effort in my muscles and calfs, but not ankle or knee pain.
So I had the crazy idea to run a marahton this year, perhaps the 2012 Chicago Marathon. I have never been much or a runner, my right knee was always hurting by KM 3. I usually run semidesertic trails (mixed - asphalt, dirt, rocks (baby goats), sandy, hard pack full of goatheads). Thus, I am aprehensive of running in such trails with the Komodos, they seem ok for asphalt and groomed (USA and Europe Trails), but I seriously doubt that they can actually take the beating in these roads (imagine a hard mountain bike tire, bein punctured 15 times in one ride).
Therefore I was searching for options, when I found the new Spyridions are coming out in February, but still I sorta like the "more" protection offered by the New Balance minimus MT10.
What are your experiences? what do you people think about it?

I´d appreciate any insight and tip!
