text: I sent these back and got a pair of Nike runners. There is almost no substance to these shoes, which I know is the point, but I am used to the NB minimal shoes, which have just a bit more feel to them. The material looked so thin on the upper that I was sure my toes would go through them in no time, and the sole was a foam so thin I was worried a small rock would come through. I run on the road mostly, and these I think are made for a track.
