I am always on the lookout for a professional, but very comfortable shoe (education field with a lot of walking). These Florsheims fit the bill and make me wonder why I never bought these before. Something about them just didn't "look" comfortable to me but man was I wrong. These are easily among my most comfortable work shoes with the bonus of also looking more professional. I will say they have some heft to them, so if that's a problem for you these may not be right for you. As for me, they are right as rain. I purchased the black and brown ones (with white souls) and they are at the top of my rotation now. I look forward to trying some more from Thai company.
