This was not my first pair of VFFs.  I've been wearing them exclusively for running/outdoor activity for about 8-9 years.  I've worn Sprints, Bikilas, and Komodos over the years, and unfortunately the quality just keeps going further and further down.  This saddens me because this footwear changed my life as far by helping me to increase my functionality and activity.
First, these were light, but the upper almost seemed to be made from a light, non-stretch perforated plastic. It felt like the material that is used to make multiuse shopping bags that you can buy everywhere, but with small holes thru out.  One thing I've had issue with in the past is that the uppers would hold so much moisture.  I don't imagine that these would as they don't seem like a normal upper material.  I honestly would worry about rips as the material just seemed odd.
The sole was very structured and rigid, more than my other pairs.
I've always, always worn a 39 in all models.  I checked the VFF site for sizing and ordered my norm.  They were about the right length, but the lack of stretch in the upper and the rigidity of the sold made these impossible to use for running.  My foot was really wedged in and they were uncomfortable to walk.
I also found the tongue of the shoe to be small and awkward, but maybe if they were a bit larger it wouldn't have been an issue.

My first VFFs gave me almost 1,000 miles of running on blacktop road.  My second pair a bit less, and now my current 3rd pair hasn't lasted even 500 miles and I have 1 inch holes in the soles.  I truly love this footwear and will continue to buy it regardless, I just would love to see a return to the quality and simplicity of the earlier designs instead of trying to fill so many niche markets.  This is the reason for my hopeful 2 stars instead of the 1 these actually seemed to deserve.
