The basic idea that I culled from the information about running in the VFF is that the lack of “support” forces a mid-foot strike. I have been trying to develop a better mid-foot strike after reading Danny Dreyer and Christopher Bergland. After running ten feet in the VFF I had an almost perfect mid-foot strike. I also experienced pleasurable feedback from the road surface. I found myself seeking out gravely areas to feel the massage like quality of the gravel underfoot. These have become my go-to training shoes.
Of course I have only run about 8.5 miles in the VFF and strange things could happen. Every once in a while I would run over a large (>1.5inch) rock sitting on the road surface and experience a somewhat painful jab. Perhaps some injury producing jab is in their not too distant future? I got the KSO VFF which do not afford much thermal protection. I purchased some Injinji socks to extend the VFF’s useful season but it will probably get too cold for using these shoes in the coming weeks.
