I'm a nurse practitioner in a hospital, and I bought these shoes as my work shoes.  I needed something stylish enough to go with my dress clothes, but comfortable enough to walk(or run!) in all day long.  These fit the bill!  They are roomy enough for my size 11 feet AND my custom insoles, and they let my feet breathe.  I have been wearing them 5 days a week, 9-10 hours a day for the past 4 months, and my only complaint is that I have 2 tears in the leather toe of the left foot - I'm not sure if I kicked something & tore it, or if the fabric just gave out.  Either way, I'm ordering another pair!
