Notes
Just got my new NB Lightweight trainers that are to be used WITHOUT SOCKS. Although I was skeptical (due to my history with blisters) I was excited to try them out. I decided to do two identical 3 mile out and backs and change shoes between them.
I was immediately impressed by how the shoes felt and they are definitely lighter than the other NB protypes and the Nike Air Spans too. I felt a couple of hot spots but overall these shoes were very comfortable. I won't run on the trail in them any more because small pebbles kick-up and go down into the shoes. I checked my feet after this 3 miler and was without blisters.
Course: Home to trail to 1.5 and back. 2 miles on asphalt, 1 mile on the trail (trail of tiny gravel on top of dirt).
