These shoes are comfortable and easy to get used to.  I  noticed a decrease in how much my belly sticks out after just a day of wearing these while I shopped.  So I am glad it helps me rather painlessly build my core strength.  I am surprised at the width of the shoe.  I wear a EE to EEEE width usually, but was able to fit comfortably into a medium width.  I tried them on in a store before ordering them here, just to be sure. They are a bit pricey, but in this case worth it.
