ive heard of Ken Bob before, read a little bit about him on a forum somewhere.
Im excited to think i could be doing a marathon in minimalist footwhere. In a few years time once ive perfected the technique i would like to complete a cross country marathon with no footwear, perhaps just a silicone sleeve which inov-8 do or something to protect from sharps.
There are shoes which will help you transition from heel-striking to mid-foot. If you wear large padded stability shoes you will find it much harder to mid foot strike due to the size of the heel on the shoe. A shoe such as the Brooks Pure Cadence which has a low heel and less "padding" will encourage you and make it a more natural feeling to mid foot strike.
I am no expert but its what im doing right now after having knee pain wearing stabilty trainers and thought i would try it myself. I agree with ratzer and think you should read more on barefoot running techniques.
