I absolutely LOVE these sneakers!!!! I do the Insanity workout program, and was wearing an old pair of Pumas.  However, every time I would work out (six days a week!), my feet would cramp from all the jumping.  I decided I needed a real pair of athletic sneakers for support.  I don't really know what is best when it comes to brands for sneakers (I'm more of a high heels gal), but these are SO COMFORTABLE.  They are so light, and the zigzag bottom is so cushiony!  I spring right back up when jumping or running, and they are also super cute!  I received them, wore them once, and immediately bought another pair in a different color!  Awesome!!
