I've worn a number of different brands. Rockports were okay, for me they felt a little too light in weight, so I felt like I had on slippers. I used to wear rubber soled Johnston & Murphy and Timberland "split-toe" mocs for work. So long as the shoes fit well and had rubber soles, I felt like I could walk in them. If you wear any hard soles, keep a pair of rubber-soled shoes on hand, in case you have to walk out.

I walked from below Wall Street to almost Woodside Queens during the 2003 blackout in a pair of Timberland "work casual" shoes. I got a good blister, took acold shower, changed an headed back into Manhattan on foot.
