Absolutely comfortable.
Size: 9, Color: Brown Multi
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.

Good enough for Trump, good enough for me.
Size: 9, Color: Black Crazy Horse
Not gonna lie, the only reason I first bought these were because Trump likes this brand of shoes and the fake media ran a story about it. Once I got them and tried them on I was shocked just how comfortable they were. These are very nice and comfortable. I will definitely be buying more from this brand. Nice job Florsheim. 45/47
