I really like the black Gucci driving loafers featured in Angie's blog post this morning. I'm wondering if they'd be good for corporate work travel, or if maybe they read too casual? Both here in the U.S. and in Europe. And what about the regional differences within both?

There are some patent ones too, which I presume would be safer but not as practical for my wardrobe in any case.

Hard tech and bio tech (the fields I work in) are kinda interesting. Things aren't suit fancy, but they're not informal either. Not that anyone actually cares.

Maybe as long as one sticks with wool trousers?
