I have the cross trainer version of these, Nike Free Hyper TR Women's Training Shoe, and absolutely love these! I posted about my trials with Under Armour, Saucony, barefoot, and then finally finding these. I don't run at all, so I can't speak to the running shoe exactly, but they are similar. I love how flexible and lightweight these are, I love that I don't experience the same foot pain I get with other shoes, I even love the way they look. I wear them for all of my dvds, they work great for kickboxing, bootcamp, hiit, turbo fire, and weight lifting., they are especially impressive for workouts with lots of jumping. I give these an A+!
