I work in a Corporate Office and it's not the corporate uniform, but I get to be the exception! (Our lab techies wear white shoes in the lab, so I pretend I'm wearing them so I can go into the lab).
The New Balance shoes have a Wide Toe Box. I wear the lace up ones, and on bad days, I loosen the laces almost all the way.
When they get a little older, I buy the inserts and it feels like a new pair of shoes all over again.
I also wear them with my Diabetic Socks. (I buy them at Walgreens) They are soft, cushiony and no seams near the toes to irritate me. The tops of my toes are very sensitive and I am very picky about shoes!
