I used these twice to workout and they are pretty good. I do have to say that I was expecting a bit more cushion and comfortability. I tried out some of the similar brands at a shoe store and expected these to be the same comfort but not the same. Other than that, they are ok and will work for my insanity workouts. I will see how they hold up to my workouts... Today is 12-9-12 so I will see how they hold up in a couple of months.
