I purchased the Reebok Women's Realflex from Sports Authority.  I love these shoes.  The good news I have just purchased another color from Amazon for almost $20 cheaper!  I highly recommend these shoes.  I have always had foot problems and have a hard time finding comfortable shoes.  I work on my feet and I also like to walk.  I was able to walk almost 2 hours after working for 8 hours and my feet did not hurt.  These are miracle shoes!
