I love these trainers.  They are pretty darn good looking for a pair of MBT's.  Despite the fact that I have MBT's to match practically any outfit, I almost want to dress down just to have an excuse to wear these!  MBT's do everything as advertised.  I have been wearing them almost exclusively for a month after an issue with plantar faschiitis.  Without a doubt they have helped with toning my legs.  I am back to working out daily without any pain.  And their construction is fantastic.  They may be expensive, but they are leaps and bounds ahead of the Sketcher Shape Ups as far as quality and feel are concerned.  Be warned - one step is all it takes to be addicted for life.....
