I have got to say that I am intrigued by the idea of less shoe. Consider, over the course of a marathon, how much less work your muscles will have to do to lift a shoe that weighs 4 ounces less. I find it hard to believe that the difference won't be noticable. I tried to wear a lighter shoe once, but I had no idea what I was doing and didn't allow for a proper adjustment period. Ryan, how did you begin the transition to a lighter shoe. Would you wear the lighter shoe for entire runs, or just a mile or two at a time? If I wear a neutral shoe now, would it be important for me to go with another neutral shoe? Or, is part of the idea to get your foot accustomed to running in any shoe? Also, would it be of any importance to have a certain weekly mileage before beginning such a transition. I am at a point now where my stride feels much lighter and more efficient than it did a month ago. I imagine that if I had tried this a month ago, I would not be thrilled with the results.
