I was thinking maybe Skechers but the selection maybe limited if this is for work. I agree with the Aerosoles. It is kind of hard to find decent support in flats. You may have to buy different kinds of arch support and sole inserts and create your own comfort for flats. I purchased some Dr. Scholl's 'custom orthotics' from a kiosk at Costco and found them not too wide but it's the thickness that makes your shoes tighter.
