I am 5'8 &these shoes make me feel taller. I like that I can adjust the arch a bit but I don't know if it makes big difference.  I feel my posture is better and my legs don't feel as tired after working 12 hrs. I also get a lot of compliments on how fun they look.  They really made me smile when they came in the mail. Also, My feet are long/narrow and they feel wide but r ok.
