Oooh, the changing shoes at work person, Jesse! Just make sure you don't become the "wearing white sneakers with your black skirt and hose" person. Because that person is WRONG.
I too have several pairs of flat Sketchers for walking to work (along with boots for winter and some nice leather flip flops for summer). I remember the Seattle F2F was like a Sketchers floor show.
And Jesse, if you keep your shoes at work you don't have to schlep them back and forth. My entire file cabinet is shoes. Weekends if I'm going out I'll take a couple of pairs home, but mostly they live at work.
