Try looking at these Rockports (standard disclaimers, no affiliations, just a happy customer). Or a similar style to suit your office environment and personal tastes, if you find the right pair they will feel almost as comfortable as your favorite walking shoes. I've worn Rockports like this for the last 12 years or so, now I am so spoiled I can't/won't wear anything else. I'm confident that mine will get me through the 10 mile walk home from work if necessary. YMMV
