Looking for Comfortable Working shoes for men with Flat Feet.?

I have flat feet problems, I went to the doctor and I got some customized Inserts. I work as a front desk clerk in a hotel and my work requires me to stand up for 8 hours. I have some Sperry shoes that i use but they are pretty worn out. Everyday i get off from work I still come home with a lot of feet pain. I wanted to know if anybody could tell me what are some well known brand of shoes that are specially made for people with my problem. If possible what store sells them so that I can try them on. (No tennis shoes).
