Query: Worst New Balance Cross Trainer I have ever had..

This is my fourth pair of New Balance Cross Trainers and these are the worse. I had the 1006 and 1005, then a pair of 600s before them. These are supposed to be the latest and greatest, but they are terrible. I do a lot of circuit training classes and I was feeling a sharp pain in my left foot whenever I bent my foot in these shoes.Very disappointing for a new balance shoe, I would not recommend and returning these shoes.
