I know we have a few Professionals of the slacks/suit and tie type on here. Does anyone have a suggestion for a dress type shoe that a guy can wear comfortably 12-13 hours a day? I start my school program next week and a program requirement is for me to wear slacks, button down shirt w/tie and dress shoes. I have to be standing tall ready to go at 7:15 AM daily, and the earliest I'll get out is 3:30, hence the extended comfort aspect.
