Already had another pair of sketchers shape-up,tie up style and decided to order the mary jane style to wear with my white uniforms at work.  I am a nurse and spend many hours on my feet with resulting back pain prior to using the sketchers shape-ups.  Due to having to maintain a better posture, my back pain at the end of my shift has almost disappeared.  Would recommend these shoes to anyone that is on their feet for long periods but the tieup style seems to offer more support.
