I finally tried these shoes. man am i disappointed. First I have to tell you that I am a neutral runner with a slight pronation. I put these shoes on and did a fast 5 mile run and noticed that there was no center support. Two days later I did 4 more and these shoes and the next day I had pain in medial part and knee. I've had to drastically cut back on training over the past few weeks. This is exactly when I should increase the distance for my half marathon. I am angry
