Yes, sneakers are great. A nice pair of high tops, if the boss will let you wear them. I can't get away with it - I have to wear "shoes", so the Magnum "Low" (sneaker height) patrol shoes pass, as do, believe it or not the 8" highs, as they cant see they are up in my pants (No jeans, but I can wear cargo pants - and DO)
I'll tell you, the day of the NYC blackout (what was it, 5 years ago already?) I was sure glad I was wearing my patrol shoes, and had my pack on (On the subway).
